Registration is free and teachers who register receive complete record-keeping of student grades. They have access to more precise test-generation tools, can create single tests with questions from different categories, can create matching and multiple choice questions, and can access a public test library. There is no reason for students to register, since the additional features are only useful for teachers.
We comply with the Children's Online Privacy Protection Act. We do not collect any personal or identifying information from children. The only information collected from students is numerical test result data. This data is private to the registered teacher and is not shared with anyone.
