Background: In the immediate aftermath of school closures related to COVID-19, efforts to unpack the impact of the pandemic on student outcomes surged. As schools have returned to fully in-person learning, that focus has shifted towards the implementation and evaluation of interventions to remediate or accelerate impacted learning. However,…

Background: Pre-k convergence refers to the tendency for the positive effects of pre-k on children's academic skills to diminish over time, observed across decades of observational and experimental studies (Ansari et al., 2020). Researchers have tested multiple mechanisms to explain convergence, with mixed results; none of the proposed mechanisms…

Background: Publicly funded four-year-old preschool (or 4K) programs have expanded over the past several decades (Friedman-Krauss et al. 2021). Many high-quality preschool programs lead to gains in academic and social skills for students (Cascio and Schanzenbach 2013; Gormley and Gayer 2005; Weiland and Yoshikawa 2013; Wong et al. 2008),…

Background: Some education programs' early positive effects disappear over time. Other programs have unanticipated positive long-term effects. Foundations have warned of the dangers of putting too much weight on in-program effects, which "often fade over time." The U.S. Department of Education's Institute of Education Sciences (IES) even…

The negative impact of COVID-19 on students persists three years after the onset of the pandemic. A substantial body of research shows that students have yet to recover to their learning trends before the pandemic (Callen et al. 2023, Lewis & Kuhfeld 2023, Cohodes et al., 2022). This suggests that students face a lengthy road to recovery, and…

Background/Context: Spurred by changes in federal policy, Response to Intervention (RTI) has witnessed increased adoption across states and districts in the past several decades (Berkeley et al., 2020). Originating in the special education field, RTI involves a shift from a uniform instructional approach to a tiered instructional approach…

Background: Much has been made of whether the evidence supporting mindfulness-based interventions (MBIs) is consistent or high-quality enough to merit their wide implementation, and numerous meta-analyses, reviews, and meta-analyses of meta-analyses have been conducted in pursuit of this question (e.g., Bockmann & Yu, 2023; Goldberg et al.,…

Innovation is the central driver of economic growth. Many growth models underscore the importance of actively directing more individuals to innovation (Romer, 1990; Jones, 2022). This goal can be achieved by providing early exposure to innovation to children, especially those from disadvantaged backgrounds (Bell et al., 2019; Akcigit et al., 2020;…

Background: This paper estimates the causal effects of an intervention under the UK-funded Partnership for Learning for All in Nigeria (PLANE). PLANE is a seven-year (2021-2028) early literacy and numeracy program that aims to improve student outcomes in Northwest Nigeria. In this region, fewer than 28% of children and youth. Numerous factors…

This paper develops models to measure growth in student achievement with a focus on the possibility of differential growth in achievement for low and high-achieving students. We consider a gap-closing model that evaluates the degree to which students in a target group -- students in the bottom quartile of measured achievement -- perform better…

Background/Context: Increasing evidence suggests a connection between racial differences in rates of exclusionary discipline (suspensions/expulsions) and academic achievement by (Losen & Martinez, 2020; Reardon et al., 2018). Black students receive out-of-school suspensions and expulsions at disproportionately higher rates, which is associated…

Background/Context: Despite increasing school enrollment, significant literacy gaps persist in developing countries, with many children unable to read by age 10. This paper evaluates "M'ap Li Net Ale," a comprehensive intervention aimed at improving early-grade reading skills in Haiti, a context characterized by limited government…

Background/Context: Mozambique has made progress over the past decade in improving both the nutrition and literacy of its population. Nevertheless, rates of illiteracy and malnutrition remain high, particularly in rural areas and among women. In most provinces in Mozambique, schools are overcrowded, student/teacher ratios are high, and reading and…

Can successful schools replicate? In a climate of school turnarounds, charter conversions, and new school openings, an important question is whether schools that have demonstrated success with in one or several schools can replicate their success with additional schools. The federal government's Investing in Innovation (i3) grant program has been…

This paper examines the "ecological validity" of a randomized controlled trial (RCT) conducted in 42 high schools to measure the impact of a content literacy program. This study of comparable schools implementing the same program in different contexts highlights characteristics that are often not attended to in rigorous effectiveness…
