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. The bars in the evaluations are not a measure of absolute safety or risk rather, they suggest areas to be considered and examined as part of using the application.

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.

Common Sense is the nation‘s leading independent non-profit organization dedicated to empowering kids to thrive in a world of media and technology.

Families, educators, and policymakers turn to Common Sense for unbiased information and trusted advice to help them learn how to harness the positive power of media and technology for all kids.
