The Maryland State Department of Education (MSDE) is a national exemplar in being transparent as it rolls out and supports a new teacher and principal evaluation (TPE) system statewide. This study focuses on how frontline educators perceive the development and implementation of the TPE system, particularly the support they received in understanding and implementing Student Learning Objectives (SLOs). Through the Mid-Atlantic Comprehensive Center, CTAC and WestEd prepared this report for MSDE. The recommendations reinforce the instructional emphasis of the new TPE system and build on the foundation of support established to date by MSDE.
