TLE Seal Program

The CoSN Trusted Learning Environment (TLE) Seal program is the nation’s only privacy framework designed specifically for school systems. The TLE program helps K12 schools and districts build strong, effective privacy programs, and a culture of trust and transparency. Earning the TLE Seal is a mark of distinction, signaling that the recipient has taken strong, measurable steps to help protect the privacy of student data.

The TLE Seal Program was developed by CoSN in collaboration with a diverse group of 28 school system leaders nationwide and with support from AASA, The School Superintendents Association, the Association of School Business Officials International (ASBO) and ASCD.

The TLE Seal Program requirements have been validated by more than 50 school systems.

TLE Seal

The TLE Seal Program requires school systems to have implemented high standards for student data privacy protections around five core practice areas: Leadership, Business, Data Security, Professional Development, and Classroom.

School systems that meet the Program requirements will earn the TLE Seal, signifying their commitment to student data privacy to their community. TLE Seal recipients commit to continuous examination and advancement of their privacy practices.
