Initiated through HB08-1384, the Teaching and Learning Conditions in Colorado (TLCC), formerly known as TELL Colorado, is a statewide, anonymous survey intended to support school, district, and state improvement planning, as well as research and policy. Schools and districts need more than 50% participation and at least five responses to access their data.

The 2020 TLCC Survey is now closed. Schools with more than 50% participation and 5 respondents will have their reports available on this website in April.

"Here in Colorado, we depend on our incredible educators to prepare the next generation for success in the workforce and in life. The TLCC survey provides meaningful, anonymous information about the challenges and opportunities educators are facing in our schools so that we can use these results to offer critical supports. On behalf of Colorado, I want to thank you for your service to our children and ask that you participate in this important survey." - Governor Jared Polis

"A new decade is an opportunity to find new, exciting ways to make Colorado the best state for teachers, and the TLCC survey is one of the best channels for teachers to let us know what they need to be successful" - Commissioner Katy Anthes
