About Privacy Evaluations

The privacy evaluations have been designed with the help and support of a consortium of schools and districts across the United States. These evaluations are designed to streamline making an informed decision about the potential privacy implications of educational technology used to support teaching and learning.

Our core evaluation criteria are freely available and will remain freely available. People are encouraged to read the questions we use and the information security primer we released. Vendors are encouraged to use our questions and the information security primer to self-evaluate. You can also learn more about our evaluation process.

Please be in touch with any questions or feedback.
