For teachers
Class mode is free. Class Pro is a separate beta for teachers, with no effect on an API plan.
Beta · as of 10 October 2026
Class Pro beta
A school year of each pupil's progress. Planned price: $4.99 a month billed yearly ($59.88), or $9.99 month to month.
Free during the beta. Nothing is charged unless you choose to pay. We'll tell you in your cabinet at least 30 days before billing starts. If you don't, classes older than 120 days stay open to read and export for 30 days after you next open your classes page, then are deleted; at the latest 400 days after they were made.

Questions people ask before clicking
Why show a price during a free beta?
Because we want to know which of these is worth building further, and a button beside a real price answers that better than a survey. Activating costs nothing and tells us something.
What happens when the beta ends?
Billing starts when the beta ends; we email you first; nothing is charged without your confirmation. There is no card on file, so nothing can be charged by accident.
Can I switch or leave?
Yes, at any time, from your account. People who chose Pro when it was shown at $9 a month keep it, at those limits, until they switch.
I need more than Lab, or something different
Say how many items a month and what you are measuring, from your account page or by emailing support@mytestatlas.com. We read every request and reply by email.
What do you store?
Per key, a count of items this minute and this month, and the plan you chose with the price you were shown. Never the items you generated, and never a key in readable form. Section 4 of the privacy policy is the binding version.
