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 K-12 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.

As the leader in providing critical guidance to meet the needs of K-12 education technology professionals, CoSN provides two core frameworks—one for individuals and one for education institutions—to demonstrate leadership and student data privacy skills, knowledge, and competencies.

Strengthen Effectiveness

The act of working through the CoSN TLE Seal Program application becomes an exercise in cross-functional collaboration, strengthening ties, and emphasizing leadership commitment to the work throughout the organization.

Build Trust and Transparency

CoSN TLE Seal recipients can demonstrate to parents and other community stakeholders that they have taken strong, measurable, and tangible steps to protect student data privacy. Change the conversation in your community from fear and privacy concerns to one based on transparency and trust in your efforts.
