The effects of comprehensive pay reform on achievement in urban schools
研究评估了达拉斯独立学区2015年基于教师效能的薪酬改革，发现该改革显著提高了数学成绩，但对阅读成绩无显著影响，且教师构成变化是数学成绩提升的主要原因。
Academic performance of disadvantaged students has been stubbornly hard to improve, particularly in urban schools. The Dallas Independent School District (Dallas ISD) addressed this problem in 2015 with a radical change in the structure of teacher compensation, basing it entirely on classroom effectiveness as determined by an evaluation system incorporating achievement growth, classroom observations and student surveys. We evaluate this institutional change with synthetic control methods that compare math and reading achievement in Dallas ISD schools with achievement for schools in other high-poverty Texas districts. We find large and significant positive effects on math achievement that increase steadily over time. For reading, there is no clear evidence of improvement in Dallas ISD relative to the synthetic control. A mechanism analysis shows that changes in teacher composition account for a majority of the math achievement increase. This research was supported by grants from the Arnold Foundation and from the CALDER Research Network. The analysis uses confidential data supplied by the Dallas Independent School District (DISD). Individuals wishing to use these data must apply for access to DISD. The conclusions of this research do not necessarily reflect the opinions or official position of the Texas Education Agency or Dallas ISD. We benefitted from helpful comments from anonymous reviewers.
