Texas Lesson Study (TXLS) is inquiry-based, job-embedded professional development where teachers work collaboratively to develop, teach, and assess research-based lessons. Training and meeting schedules for TXLS are tailored to fit each campus' needs. Teacher-designed lessons created as part of TXLS are video recorded and available on the Texas Gateway. TXLS is part of the TEA Strategic Plan 2017–2021, set forth by Commissioner Mike Morath.
