Teaching and Learning Conditions Colorado Survey

TLCC Survey Overview

The main purposes of the TLCC Survey are to:

Amplify Educators' Voice

Provides schools, district and state policymakers with reliable data on teaching and learning conditions. It offers additional information for discussion and gives potential suggestions on areas that deserve attention in a school environment.

Deepen Improvement Planning

Provides additional data to support school improvement efforts (e.g., root cause analysis in the Unified Improvement Plan). The survey data can help staff to identify positive trends in school conditions, as well as identify areas that merit further discussion. This is the only data source on school conditions that offer state comparison points.

Strengthen Research and Policy

Informs researchers and policymakers by providing data on the impact of school conditions on student growth and on staff retention. This survey provides a unique look into schools across the state that can lead to more informed policies and practices.

The survey is operated through a statewide collaborative that includes partners such as the Colorado Education Association, Colorado Education Initiative, Governor's Office, Colorado Association of School Boards, Colorado Association of School Executives, Colorado League of Charter Schools, representatives from school districts, universities and researchers.
