Many states and school districts in the United States use standardized test scores to compute annual measures of student achievement progress and then use school-level averages of these growth measures for various reporting and diagnostic purposes. These aggregate growth measures can vary consequentially from year to year for the same school,…

Student growth percentiles (SGPs) express students' current observed scores as percentile ranks in the distribution of scores among students with the same prior-year scores. A common concern about SGPs at the student level, and mean or median SGPs (MGPs) at the aggregate level, is potential bias due to test measurement error (ME). Shang,…

This article suggests two alternative statistical approaches for estimating student growth percentiles (SGP). The first is to estimate percentile ranks of current test scores conditional on past test scores directly, by modeling the conditional cumulative distribution functions, rather than indirectly through quantile regressions. This would…

Student Growth Percentiles (SGPs) increasingly are being used in the United States for inferences about student achievement growth and educator effectiveness. Emerging research has indicated that SGPs estimated from observed test scores have large measurement errors. As such, little is known about "true" SGPs, which are defined in terms…

The Project on Incentives in Teaching (POINT) was a three-year study testing the hypothesis that rewarding teachers for improved student scores on standardized tests would cause scores to rise. Results, as described in Springer et al. (2010b), did not confirm this hypothesis. In this article we provide additional information on the POINT study…

This paper presents the results of a rigorous experiment examining the impact of pay for performance on student achievement and instructional practice. This study, conducted by the National Center on Performance Incentives in partnership with the RAND Corporation examines an experimental pay for performance program administered via a randomized…

The Project on Incentives in Teaching (POINT) was a three-year study conducted in the Metropolitan Nashville School System from 2006-07 through 2008-09, in which middle school mathematics teachers voluntarily participated in a controlled experiment to assess the effect of financial rewards for teachers whose students showed unusually large gains…

Many policymakers suggest that school-based reading coaches can improve teachers' practice, which consequently will improve students' literacy skills. Although reading coaches are increasingly prevalent in schools nationwide, empirical evidence for their effects on student achievement is scarce. This article helps to address this gap by conducting…

In an effort to explore the impact of performance incentives in education, the National Center on Performance Incentives (NCPI) partnered with the Metropolitan Nashville Public Schools (MNPS) to conduct the Project on Incentives in Teaching, or POINT. The study examines the effects on student outcomes of paying eligible teachers bonuses of up to…

In this study, data from ECLS-K are used to estimate the degree to which specific aspects of teacher training--the teaching credential and coursework in pedagogy--and teaching experience are associated with student achievement. In addition, the study identifies the teacher-reported instructional practices associated with student achievement gains…
