“…Though the evidence on performance or "merit" based pay is mixed, several recent experimental evaluation studies revealed limited, if any, change in student achievement, teacher motivation, attitudes, or instructional practice over time (Marsh et al, 2011;Springer et al, 2012;Yuan et al, 2013). Furthermore, recent scholarship has revealed some unintended consequences of current U.S. teacher evaluation policy, such as: lack of support and/or guidance in the use of teacher evaluation results (Amrein-Beardsley & Collins, 2012;Ford et al, 2017); lack of validity and/or reliability (either real or perceived) of evaluation results (Darling-Hammond et al, 2012;Ford et al, 2016;Jiang, Sporte, & Luppescu, 2015;Longo-Schmid, 2016;Reddy et al, 2017); and evidence of increase in adverse affective states for teachers subjected to high-stakes evaluation, such as high stress and anxiety as well as decreased job satisfaction, professional commitment, and turnover (Ford et al, 2017;Hewitt, 2015;Holloway & Brass, 2017;Ingersoll et al, 2016;Jiang et al, 2015).…”
