Retention in kindergarten involves holding students back from advancing to the next grade level due to unresolved learning gaps. This practice has been the subject of continuous research as educational experts seek to balance the potential developmental risks of prolonging kindergarten by providing students an additional year to fill their…

This article examines medium-term trends in global preschool enrolment and attendance by income category, revealing a slowdown in expansion in middle- and high-income countries starting in 2013, followed by low-income countries in 2015. By 2020, the gross enrolment ratio had plateaued at 60.8 per cent. The analysis indicates that conditions for…

In this pre-registered study, we explored the impacts of Boston Pre-K on children's educational trajectories, school progress/engagement, and academic achievement in late elementary and middle school using lotteries for oversubscribed schools in 2007-2011 (N=3,092 students; 24% of all applicants). Importantly, the program was unique nationally in…

This brief describes patterns of student homelessness and education indicators in Camden City School District. Students who experience homelessness are more likely to enroll late, transfer early, or both. They are enrolled for fewer days, on average, and more likely to repeat a grade, change school mid-year, and be chronically absent. These…

Will students who have not mastered kindergarten skills benefit from another year of kindergarten before going into grade one? It has been suggested that there is no other topic in education that has such a wide difference of opinion as those researchers who do not advocate retention and those who are convinced that a child should be given another…

The paper argues that in many developing countries there is a set of linked symptoms in education systems that cohere into what we call a weak foundations syndrome. Multi-source evidence is presented to illustrate how weak foundations through the early years of schooling lead to low primary school completion. Symptoms of the syndrome include (1)…

This article is the fourth in a series arguing that there is serious mismeasurement of enrolment in early childhood development (ECD) and in the early grades of education systems in many countries, especially, and most damagingly, in those making the most progress on access to schooling and in the sustainable development goals. Other reports have…

Nationwide, the percentage of four-year-olds enrolled in state-supported preschool programs has more than doubled since the early 2000s as states dramatically increased their investments in early childhood education. Florida's Voluntary Pre-kindergarten Program (VPK), which began in 2005, has been a national leader with respect to preschool…

This study leverages naturally occurring lotteries for oversubscribed Boston Public Schools prekindergarten program sites between 2007 and 2011, for 3,182 children (M = 4.5 years old) to estimate the impacts of winning a first choice lottery and enrolling in Boston prekindergarten versus losing a first choice lottery and not enrolling on…

This paper presents new benefit-cost estimates for the Tulsa universal preschool program. These calculations are based on estimated effects from previous papers of Tulsa pre-K on high school graduation rates and college attendance rates of students who were enrolled in kindergarten in Tulsa Public Schools in the fall of 2006. In this paper,…

We use event history analysis on an aggregate dataset from 1997 to 2018 to understand the state-level antecedents associated with the adoption of test-based grade retention policies. Findings indicate that the educational conditions of a state to be more predictive of retention policy adoption than the political, economic, and geographic measures.…

The READ Act is the signature literacy legislation in Colorado that prioritizes early literacy by ensuring all students achieve early-grade reading proficiency for later academic success. In 2019, the Colorado General Assembly passed significant revisions to the READ Act in Senate Bill 19-199 (S.B. 19-199), which were signed into law by the…

While there is a consensus that attending preschool better prepares children for kindergarten, evidence on the factors that sustain the preschool boost into the early elementary years is still emerging. To add to this literature, we use lottery data from applicants to oversubscribed schools in Boston Public Schools (BPS) prekindergarten program to…

The Reading to Ensure Academic Development (READ) Act is the signature literacy statute in Colorado. The READ Act prioritizes early literacy by ensuring all students achieve early-grade reading proficiency for later academic success. In 2019, the Colorado General Assembly passed revisions to the READ Act in S.B. 19-199, which were signed into law…

The Arkansas Better Chance (ABC) program longitudinal study (2009-2020) reviews the changing circumstances and outcomes of participation in Pre-K services in Arkansas. The "core comparison" of this study is between ABC participants and students who had no known Pre-K participation but have similar household income levels. The results…
