Create your classroom account

One account for you. Your students join as profiles; they never sign up, and they never type their name.

At least 8 characters. No uppercase-and-a-number rules: length is what matters, and those rules just produce passwords people write down.

Two fields. That is the whole form.

Everything else is asked later, in the moment it is needed, where we can explain why. Going from four fields to three raised completions by about half in 40,000 forms.

We never ask for a child's name, email, photo or date of birth.
