NIET [National Institute for Excellence in Teaching] continually evaluates the impact of TAP: The System for Teacher and Student Advancement on raising student achievement, improving instruction and increasing the ability of high-need schools to recruit, retain and support effective teachers. In addition to national results in student achievement and teacher attitudes, the June 2017 report highlights findings from the Minnesota, Iowa and Tennessee TIF-4 [Teacher Incentive Fund] sites, the TAP System in Texas, and the higher education partnerships supported by Supporting Educator Effectiveness Development (SEED) grants.
