Tracking changes in state standards, school practices, and student achievement	2017	23	.pdf	application/pdf	9516	391	47	7 Specifically, the following state-level predictors were included in the regression model to account for possible CCSS policy mechanism: (1) the rigor of state proficiency standards, (2) school program alignment with state curriculum standards, and (3) school program alignment with state/district assessment results (see Appendix). The V-shape trend of state proficiency standards, particularly with post-CCSS growth spurt in 2015, implies that the adoption of CCSS-aligned tests may have contributed to making the state tests harder and raising the bar for student proficiency, thus reversing the earlier downward trend of state proficiency standards (i.e., race to the bottom phenomenon) under the NCLB high-stakes testing policy.	cache/epaa-2834.pdf	txt/epaa-2834.txt
