The Houston Independent School District (HISD) launched the Effective Teachers Initiative in 2010 in order to provide every student in HISD excellent instruction. As part of this initiative, HISD implemented the Teacher Appraisal and Development System (TADS) in 2011-2012 school year to provide teachers, principals, and district officials the information they need to improve instructional practice, to inform staffing decisions, and to ensure every student receives effective teaching. This report documents teacher appraisal outcomes from 2013-2014 with historical data from the program's inception since 2011-2012. Teacher appraisal outcomes are summarized by each appraisal rating: instructional practice, professional expectations, and student performance. Finally, each appraisal rating is then examined according to select teacher and campus level variables, including school academic level, accountability ratings, and teacher characteristics.
