About us

TPT (formerly Teachers Pay Teachers) exists to empower teachers to teach at their best. We’re the go-to platform for supporting educators with the resources they need to teach successfully in an ever-changing education landscape. Today, educators turn to TPT to find the world's largest catalog of educator-created learning content and tools for interactive digital instruction. Districts and schools can also support teachers by opting for a TPT School Access subscription, which includes Easel by TPT. More than 7 million educators — including 85% of PreK-12 U.S. teachers — use TPT to save time, engage students, and learn from each other.

TpT was founded in 2006 by Paul Edelman. After spending years as an educator in the New York City public schools system, Paul decided to solve a real problem he struggled with every day – finding and sharing educational content with colleagues. What began as a humble exchange for teachers looking to share lesson plans has since exploded into an education powerhouse. If you’ve never heard of TpT and want to learn more, just ask a teacher about us.

If you want to solve big problems at scale, work with colleagues who have a deep curiosity for learning, and build things that make a meaningful impact, reach out to us!

Has potential, needs work.

This app has so much potential to be great, but it’s really not incredibly useful as it is. My main wishes for improvement are these: 1. Clear and easy access to the back end of your own product - currently you can only view it as a buyer would. I’d like to be able to, for example, edit the description from my phone if I see an error.2. Feedback counter reset- currently it does not reset when you view new feedback, so the number is more accurately called “feedback received since installing the app� instead of “new feedback�.3. Share functionality- it needs the ability to provide a shareable link for products. This is a huge deal for marketing. 4. Feedback- currently you cannot leave feedback at all through the app. The more accessible feedback is, the more likely it is to be provided.

Limited Viewing Ability

LOVED this app when I first got it several months ago. I was legit addicted and was always on it. But I’m not sure what happened... anytime I am on the app and I do a search for what I’m looking for it will maybe show me 6-8 items that fit that search and that’s it- they just keep repeating in the same order over and over when you scroll. But when I search on the computer for the same thing... there are thousands of hits. I have really stopped using the app because I literally can’t find what I need. PLEASE change it back so that I can use the, much more convenient, app again.

Love this app

This app has provided many resources for my coursework especially out in the field as I am a grad sped education major at Xavier University. These resources are often free or I pay a small fee of 5 dollars or less for materials that have already been created for me which is obviously extremely helpful. However, being “a broke college student� I often find materials that I wish were priced lower or could be free such as calendars and other editable materials. I do understand that this is a side business for some teachers but maybe adding a category for students in college or a special discount for students in college is needed. Overall I have found this app and website very helpful and I continue to use it.

Teachers Pay Teachers: Everything You Need To Know—Get Started Harnessing the Value of Top Quality Educational Resources

By

Cristian T. Duque

March 9, 2023

--- Advertisement ---

Teachers looking for an opportunity to showcase fantastic learning resources. Curators looking to develop the perfect, curriculum-aligned collection. Professionals who just want a quality piece of content on the go. All of these groups can benefit from Teachers Pay Teachers (TpT), one of today’s most popular marketplaces for digital educational content.

Paul Edelmand founded TpT in 2006. A New York City Public School teacher at the time, Paul’s goal was to create a place for educators to collaborate on quality educational resources. According to TpT’s own website, more than 7 million active users—85% of them U.S. “Pre-K-to-12” teachers—and an estimated near one million sellers, access a variety of formats. These formats include interactive, curriculum and standards-aligned, and culturally sensitive content. Recently a new offering, Easel, allows teachers to deliver the marketplace content directly to their students through a dedicated, LMS-like platform. TpT states that it complies with applicable requirements from student and user privacy regulations including COPPA and FERPA.

In March 2, 2023, IXL Learning, owner of learning brands including Rosetta Stone, Education.com and Vocabulary.com, announced the acquisition of TpT for an undisclosed amount. CEO Joe Holland, who would perform various senior leadership positions at the company since 2014, announced to be stepping down.

So, how does TpT work, and how can you make it work for you? We’re counting on the information, consideration and proven practices in this article to inspire you and give you a clear path of success with TpT. Read on!

Get started in Teachers Pay Teachers by exploring the massive directory of content and bundles. Use categories, filters and ratings to find the best content for your needs

TPT or Teachers Pay Teachers content catalog

Use categories, filters and ratings to find the best content for your needs. On the homepage, the “Browse Catalog” option launches a comprehensive menu of categories, including grade, subject, price and format. Click on your must-have content attribute to launch the catalog.

Surprisingly, there’s no way to simply access a list of top-rated content. However, the catalog will likely appear sorted by rating. From the catalog you can apply a mix of filters, sorting criteria and views, as well as the search bar.

eLearn Pro Tip: Looking for content or inspiration themed to an upcoming holiday, or a movie that just premiered—i.e. “Wakanda Curriculum”—in a pinch? Click on the search bar for a list of trending search topics.

TpT is an online marketplace, but you will find a wealth of highly-rated content completely free

Teachers are known for having big hearts, right? For many, TpT is an opportunity to share lessons, activities, plans, worksheets, and even complete courses free of charge. Creators may have needed to produce these materials for their own lessons, or thought it would be good to just make and share without expecting monetary compensation in return. Others, more strategically, offer free previews of their portfolio as a sneak peek to their complete offering. Experienced TpT sellers have put significant time into their “Stores” or profile pages, which users can “follow,” provide ratings, leave reviews, or ask a question. Content often includes the creator’s branding, website, or watermark.

TPT or Teachers Pay Teachers sample content profile page

All content, free and paid for, has its own download page, which includes further details, pics, ratings and reviews. Downloading the content or adding it to a collection or “wishlist” requires an account.

eLearn Pro Tip: Check out free and fully open-source content in our Virtual Learning Online Activities Guide

Signing up for a TpT account is free. You can choose a buyer or seller membership, or both 

TPT or Teachers Pay Teachers signup page

When you sign-up, you can choose a buyer or seller membership, or bot. Signing up only as a buyer is free. All content you check out, paid or free, will appear in your personal purchases section. You can create collections of the content you’ve acquired in this same section. You can share these collections, or make them publicly available. Unfortunately there seems to be no straightforward way to search for user-generated public collections.

Buying content is a matter of clicking the button and checking out using the shopping cart. Before purchasing, pay attention to the licensing restrictions on the item, you may only be getting a single license for your content which forbids you from sharing your access. TpT is integrated with Google Drive, and in some cases your access gets linked to one specific Google account.

eLearn Pro Tip: Take advantage of the TpT credits program for buyers, which gives you a dollar in credits for each dollar spent on an “activated” item to which you provided a rating. The program does not apply for free or inactive content, or content purchased with credits or gift cards.

TpT is a community-driven platform. Resources are created and reviewed by other teachers

TPT or Teachers Pay Teachers community page

TpT appears to downplay the community aspect of its platform, despite the significant weight it may hold. Ratings and user reports are the main ways high-quality content on TpT becomes easy to access, and the method through which poor or non-compliant content gets reported to TpT staff. There has been at least one instance of infringement not being flagged until members denounced it and news coverage followed.

On the upside, the importance of catering towards the community means reputation is a valuable token. Top sellers tend to be highly responsive to questions or content-related issues raised. Refunds are optional—with exceptions valid for up to a year—but it’s a widespread practice to offer a refund with no questions asked.

A TpT-branded online community space is available, but with null activity in the past 6 months.

eLearn Pro Tip: As a seller, consider offering quality free content not only as a showcase of your product, but as a way to maintain your creations as active resources that are shared and discussed by a section of the public. This will also make them a source of feedback and ideas. A teacher customer turned seller claims TpT taught her “more about lesson planning, scaffolding, and teaching than college or mentors ever did.”

TpT is a great resource for finding new ideas and inspiration, as well as to share and sell your own resources

TPT or Teachers Pay Teachers seller upload page

Have you ever thought about joining the educational creative economy? Digitally adept instructional designers, former teachers turned influencers, evangelists or community educators are nowadays the building blocks of thriving new markets and sources of value.

There’s a clear recipe for success in obtaining a positive return in becoming a TpT seller. But beware: if the initial amount of investment and effort before starting to get results, the likely lifestyle, and the overall level of enjoyment of the tasks involved, are all acceptable for you, here is the way you can get started creating content that sells on TpT:

Define your motivations, the “core value” that clearly and easily define your content, and your best related skills. Brainstorm quality content ideas you would be able to deliver. Then there’s no shortcut: go ahead and get it done.

Sign up for a free or premium seller account. Note that unless you have files over 1GB, or until the additional percentage earnings and lower transaction fees will offset the $60 USD annual premium membership fee, the free tier is perfect to get started.

Upload your content with descriptions and screenshots that reflect your product clearly. Take advantage of the many input fields available to ensure your content is highly searchable. Unfortunately TpT only reveals basic user trends or popular searches when using the search features, so there’s limited strategic value from studying this data to determine content needs.

Consider asking the help of a virtual assistant to streamline your day-to-day and focus on your core source of value, 4-Hour Workweek style. With smart planning, TpT can become a steady passive income stream.

Set expectations, sales and revenue goals in advance to review and adjust regularly. Performance evaluation on a monthly basis is recommended. Plan for a period of 3 to 6 months before you start to see a more dependable stream.

Keep on sharpening your skills and streamlining your process. TpT offers free guides on TpT University, and additional paid-for marketing services. The promotion for an upcoming sellers conference taking place in Boston this July is underway.

A small number of TpT’s top sellers make multi-million dollar yearly income figures and a number of other participants live exclusively off of TpT. The majority of the seller demographic are side-gig earners.

eLearn Pro Tip: If you are a U.S. resident keep in mind that, while copyright law allows for the use of protected content for educational purposes, the educational exception does not extend to the sale of said materials. So if your materials contain protected content, you may only be able to make it available for free.

TpT isn’t just for K-12 teachers. It also has resources and features other forms of education for professionals at large

Due to its reach and longevity, TpT isn’t only a top educational marketplace, but an established content market, competing with the likes of Amazon, app stores or Taobao in key categories. In addition to educational resources, you may also find general purpose templates, clipart, fonts and similar, non-specific assets.

For institutions, specialized programs for procurement each way are available. TpT’s School Access subscription offers institution-wide content licensing. For a growing number of social media niche stars, and educational media companies alike, TpT is becoming an intriguing new outlet. A publisher membership has debuted with limited access.

In organizations where CLOs have a seat at the table, learning and teaching activities often extend beyond the training department. Coaching programs, group studies, and the development of the company leader as educator, are steadily stimulating new demand for educational resources online, and that’s reflected in TpT.

eLearn Pro Tip: If you have curriculum-aligned content, take advantage of the Standards Crosswalking feature to add equivalent regional nomenclatures from several compatible Departments of Education in the U.S.

TpT is a large and reputable platform with a growing user base. Most TpT users are in the U.S. (75%), Canada (4.5%), the Philippines (4.2%) and India (3.8%)

According to data from Semrush —queried at publication—, TpT had an estimated traffic of 8.3 million unique users in January 2023, over 5.3 million coming from search engines and 365K from paid ads. TpT has been covered in media including The New York Times and New York Magazine. Educational creators websites and blogs appear to be the most common source of quality backlink traffic.

Initially bootstrapped, firms involved in capitalizing on the platform include EdTech financing specialists Spectrum Equity (involved with Lynda.com and ExamSoft) along with general VCs Tiger Global and True Ventures. The acquisition by IXL Learning alludes to its revenue generation potential, unfortunately the private status of both IXL and TpT, and the lack of public details on the deal, makes a valuation uncertain, if likely in the multi-billion-dollar range.

Percentages on sales are TpT’s main source of revenue, which is varied but not necessarily diversified. Memberships and marketing services complete the set of streams, all ultimately depending on content buyers. This makes brand reputation, customer support and a clear process to address complaints critical for its future prospects. Popularity has remained steady but below all-time highs in 2020. Additional revenue streams such as Easel or the institutional programs have not shared financial or operational performance yet.

Good day sir/madam.

Wondering if TpT can allow a Nigerian version where payment will be in loxal currency. The reason being the difficulty in making payment online from Nigeria?

Dear Ms. Nonye,

I believe you can make purchases in TpT using an internationally valid credit card. If your bank is unable to provide you with one, you can try an international payments alternative such as Wise.com or Payoneer. Hope this helps!

7 Tips for Opening a Teachers Pay Teachers Store—From a Veteran Seller The best advice I’ve picked up along the way.

By Meghan Mathis

Oct 11, 2018

By now most teachers have heard of Teachers Pay Teachers, the “world’s most popular online marketplace for original educational resources.” Some of us may have even spent way too much money there!

Have you ever wondered what it might be like to open a store and sell your own resources? If it’s something you’ve considered or if you’re just curious about what it’s like, read on! I’ve been in your shoes, wondering if I should open a store and whether or not anyone would want to purchase my resources. I’ve worked hard on my own  TPT store to build a following. And here are the best Teachers Pay Teachers tips I’ve learned along the way.

1. Look before you leap.

Signing up for a store is super simple. You can become a teacher-seller for free. You fill out some information, choose a store name (or just use your own name), and start uploading your resources immediately. If you decide to upgrade to the premium seller account, it will cost you $59.95 annually, but you’ll receive more from each sale along with some other perks.

That being said, take some time to look at the lessons and activities you might offer in your store and then check out the competition already in place on TpT. Do you have great ideas, but there are already dozens of resources just like the ones you would be offering? If so, you might want to explore other areas of focus or develop a different niche. Think your resources are fabulous and are willing to jump into a competitive market? Great!

2. Consider any offline implications.

It might be hard to imagine becoming “famous” from selling teacher lesson plans online, but that is exactly what has happened to many teachers because of TpT and their success on the site and on their blogs. While your first thought might be “uh, sign me up,” make sure that you give some consideration to how online notoriety might play out in your offline life.

While it may be possible for you to remain “anonymous” for a while, if your store does well you may find teachers in your building who discover your resources on TpT. Are you going to be comfortable with them knowing you sell lesson plans online? Will your administrator and district be supportive? Check your contract—some have pretty specific wording about who owns the resources created for use in their district classrooms. (Hint: It’s probably not you!).

This isn’t meant to scare anyone, but it is something to consider. While you may not ever become insta-famous like Brittany Sinitch, the Five Foot One Teacher, who has over 100k Instagram and YouTube followers, you should think about what it might mean for you personally if your principal and teacher friends knew you were selling your resources online.

3. Develop your customer avatar.

Don’t panic if your first response is something like, “Huh? My customer what?” Your avatar has nothing to do with that movie with the big blue people. It’s a business concept about making sure you have a lock on exactly who your products are for. Who is going to be buying the lessons and activities you’re going to sell? If your only answer is, “a teacher,” then take some time to dig deeper.

My customer avatar is Tara. She’s 28. She’s been teaching high school English and reading for about four or five years. She loves teaching but is definitely overwhelmed by all the other expectations that go into being an educator. She jogs daily, loves coffee a bit too much, and adores her dog. She’s married and loves keeping up with the latest ideas in education. She is always willing to try something new in her classroom, especially if she thinks her students will be interested in it. When she visits TpT, she’s looking for an awesome new activity or inspiring new way to start a unit she already teaches. She wants something that looks amazing and not babyish, something that is “print-and-go” ready, and something that will make her students think she rocks.

Too detailed? You have no idea. I’ve spent a lot of time thinking about Tara. I could tell you what brand of mascara she prefers and what novel she just finished reading (The Hate U Give, btw, and she thought it was A-maz-ing!). Why do I know so much about an imaginary person? Because when I create a new product, I’m not just randomly putting some activities together and hoping they’ll sell. I’m making a resource for Tara. And for the hopefully hundreds (or thousands!) of teachers like her. Because online marketing experts know that if you design resources for everyone…you design products that don’t work for anyone. So before you start, think carefully about who is going to be buying your lesson plans. Keep him/her in mind at all times.

4. Think about branding.

Having a good name and logo can really help with branding. Are you going to list products under your name? That’s awesome! It’s a choice many teacher-sellers swear by, because it lets educators buying your products know that you are a real person and can inspire confidence and loyalty.

On the other hand, it also means that anyone searching around on the web can find out you have a TpT store. While this is becoming increasingly common, some store owners aren’t quite ready to let their school districts, colleagues, and students’ parents know about their side-gig. In the end, do what makes you feel comfortable. You can always change it later.

Choosing a cute name for your store? That’s fantastic! Done right, a fun store name can become instantly recognizable to the teachers who buy your lesson plans. But put thought into it. Can you continue to use the name if you switched subjects or grades? Is something similar already being used? Is it too cutesy? You want to be happy with it for a long time.

5. You don’t have to be a tech-whiz, but be prepared to learn.

The team of techies at Teachers Pay Teachers have really made the process of uploading your resources as easy as possible. The system is logical and easy to follow. Between that and their amazing customer and seller support systems, anyone from a first-year teacher to a 25-year veteran can start getting resources into their stores with ease.

There will absolutely be things you’ll need to learn, however, like how to secure your PDF files so buyers can change your resources, how to find royalty free clip art and photos, or how to respond to angry teacher-buyers. The TpT forums are amazingly helpful, with other teacher-sellers coming together to support one another, but be prepared for having to learn some new tricks along the way.

6. Prepare yourself for updating and improving your favorite lessons.

While you may have a flash drive full of awesome ideas, teachers are now coming to Teachers Pay Teachers expecting polished, professional-looking resources. You may have an amazing lesson that you know students love but be prepared to put some additional time and energy into making your plans look like something people would pay money to use in their classrooms.

To give you an idea of how much things have changed, here’s the before and after cover of a resource I uploaded to my store when I joined TpT in 2009. Just a fun, little activity that was great for launching some novel units. This past summer I went through my resources and updated the ones that no longer met the standards teacher-buyers look for when they come to TpT. This one definitely fit the bill. I did a total overhaul on the resource and it took me several days. But the difference is obvious. I didn’t just update the graphics, I looked at the entire activity, added more hands-on pieces, made sure to incorporate background building elements, and made it more user-friendly for teachers and students—everything I want a teacher-buyer to know they’ll get when they purchase one of my resources.

Teachers expect quality graphics and fonts, answer keys, and detailed teacher’s guides. It takes time, but it can be worth it in the long run. Fortunately, it is a great time to be an online curriculum designer! Websites like Pexels and Pixabay offer clip art and stock photos teachers can use for free. Even Teachers Pay Teachers itself has numerous amazing clip art stores run by designers creating images just for educators.

Websites like Canva not only allow you to create professional-looking covers with images, borders, and creative fonts for free, but they also have free graphic design lessons so you can improve your design skills!

7. Get involved with the TpT community.

Maybe it is because teachers are naturally empathetic, nurturing people, but the TpT community is pretty darn great. You won’t find a more supportive, encouraging community of businesspeople than the sellers at Teachers Pay Teachers. Once you’ve joined, start chatting with people in the TpT forums or join a Facebook group or two. Every new seller will find lots of people willing to point them in the right direction.

By and large, Teachers Pay Teachers sellers want to help others succeed. It’s pretty inspiring. Don’t be afraid to reach out to a teacher-seller you respect to ask them a question or two or just to say hi. You’d be surprised by how eager they are to help you out! Hey, email me! If you have questions about starting a store, I’d be happy to help you out!

The truly great thing about Teachers Pay Teachers is that there really is no wrong way to do it. Start a store, put one good resource in it … and then get busy at school and don’t touch it for a year? Fine! Create your store and then immediately begin stocking it with great plans that you stayed up until 3 AM creating? If that’s what you want to do, awesome! But don’t let what other people are doing scare you or intimidate you. Remember, if you’re thinking about starting a store, it’s probably because you know you have some great ideas that other teachers would benefit from. Give it a try.

TPT: Controls testing made easy

With TPT, you can test ECU software and embedded control systems in all development phases such as Model-in-the-loop (MiL testing), Software-in-the-loop (SiL testing), Processor-in-the-loop (PiL testing), Hardware-in-the-loop (HiL testing), ECU testing and vehicle testing. Whether you create a simple module test or a complex system test: TPT provides unique features to create those tests intuitively and flexibly.

Safety standard directives can be satisfied while testing with TPT up to the highest safety level. Relevant standards, such as ISO 26262, are well supported.TPT supports all testing activities from test case design/generation, test execution, test assessment and reporting, as well as test management and requirements traceability.

Watch now: First steps with TPT

Test case design and test case generation

We designed TPT to be the best tool for testing signal-oriented systems. With TPT your test case design is very powerful, easy to handle and easy to maintain even for complex systems with large interfaces.

Test cases in TPT are intuitively modeled with a unique combination of graphical automatons and test steps. This combination gives your tests a clear structure with powerful features to manipulate and observe signals and actions during tests.

Synthesized signals, measurement data and function calls are easily integrated in the test cases. Test cases created with TPT are reactive, thus the tests can react on the system’s behavior during the test run.

More about test modeling

TPT is able to automatically generate test cases in many different ways. Most sophisticated is the test case generation of code coverage tests for Simulink, TargetLink and Stateflow models as well as for C-code

Test assessment and reporting

Automated tests require automated assessment of the test results to allow a really efficient workflow. TPT supports you with fully automated assessment features and generation of test reports. TPT supports many powerful features for all kinds of assessments: from very simple to highly complex ones.In all cases you can start by verifying the test results manually using the TPT signal viewer. The signal viewer is a powerful tool that allows you to analyse and compare signals in every detail. This helps to localize problems and anomalies and to formulate reproducible assessment rules.It is very simple to use expected results in the test design or to formulate general assessment rules that can be checked independent of the test cases. In TPT you will find powerful user interfaces for assessment rules and a feature rich editor for a unique scripting language for the test assessment based on Python. Thanks to the auto-completion and the extensive help in TPT, both approaches are easy to manage.Finally, a detailed and configurable test report containing the computed test results and relevant test data is created for your test management.

Requirements tracing

You can import requirements to TPT and link them with test cases in order to monitor the requirements coverage. Using the assessment feature of TPT (assesslets), you can automatically check and document if the test cases fulfilled the requirements or not.

Requirements can be linked to test cases, state variants, and to assessment rules

Dashboard – Interactive testing

The Dashboard by PikeTec is a free configurable tool to create user interfaces in TPT for the system under test. You can work with widgets like sliders, gauges, buttons, and images. The Dashboard can be used both for manual testing and system observation. The interactions with the Dashboard can be recorded and transformed into test cases. The Dashboard is also useful to virtually test control panels.
