Because of the amount of information that needs to be processed for each student, rostering more than 80 students in a single class or more than 500 students in a single account will lead to issues with your teacher account, such as:
- Delays in displaying the student roster
- Issues loading some pages, such as the Teacher Dashboard, which may effect accessing reporting and assignment features.
Here's an example of what you might see if your account has more than the recommended number of rostered students in a class or in your teacher account:
Once you have exceeded the recommended limit of rostered students, a warning banner will appear at the top of the Teacher Dashboard, stating: Some features might load slowly, or be disabled when you have over 100 students in a class or over 1,000 students.
If you start having trouble with your student roster or with loading pages in your Teacher Dashboard and the warning banner has appeared in your Teacher Dashboard, the best solution is to un-roster as many students as you can. It's essential that the number of rostered students remains under 80 students per class and under 500 total students per teacher account.
If you must coach or need data on more than 80 students per class or 500 students total, we recommend that you create multiple Khan Academy accounts to host different classes and prevent running into this issue.
