Background: Since the COVID-19 pandemic, American students have demonstrated substantial losses in achievement (Amplify, 2021; Domingue et al., 2021; Dorn et al., 2020; Storey & Zhang, 2023), while chronic absenteeism doubled after the pandemic, with the largest increase among low-income students (Chang et al., 2022; Dorn et al., 2021). Among…

It is well documented that teachers can have profound effects on student outcomes. Empirical estimates find that a one standard deviation increase in teacher quality raises student test achievement by 10 to 25 percent of a standard deviation. More recent evidence shows that the effectiveness of teachers can affect long-term student outcomes, such…

Recent federal policy initiatives are aimed at improving disadvantaged students' access to effective teaching. These efforts, including Race to the Top and the Teacher Incentive Fund, arise from concerns that disadvantaged students are taught by less effective teachers. A growing body of research uses value-added analysis to measure teacher…

High-performing teachers tend to seek out positions at more affluent or academically challenging schools, which tend to hire more experienced, effective educators. Consequently, low-income and minority students are more likely to attend schools with less experienced and less effective educators (see, for example, DeMonte & Hanna, 2014; Office…

This paper is the first summary of two studies and 10 years of evaluating the Milwaukee Parental Choice (voucher) Program (MPCP). This paper discusses school voucher evaluations in general terms and how these studies are carried out. The paper outlines the types of studies completed in "Study I" and "Study II" and the results…

Value-added modeling (VAM), one class of statistical models used to estimate individual teacher's or school's contribution to student achievement based on student test score growth between consecutive years, has become increasingly popular in the last decades. Despite the increasing popularity of VAM, many researchers are concerned about the…
