This is an executive summary of a full report that helps stakeholders of Professional Pathways for Teachers (PPfT) understand and refine the methods used to measure program implementation and outcomes. The full report also contains summative data on the progress of PPfT, having just completed its third year. PPfT first launched district-wide in AISD in the 2016-2017 school year, and since then the concept behind the program has been refined to that of empowering teachers and improving the quality of teaching through a multi-measure appraisal and compensation system.
