 # Texas Lesson Study 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. TXLS is part of the TEA strategic plan 2017-2023, set forth by Commissioner Mike Morath.
