Background/Context: Despite the surge in efficacy studies, a recent meta-analysis indicates that the relative effectiveness of any two math interventions is largely unknown (Nelson & McMaster, 2019). Additionally, policy makers rarely choose educational programs based on an assessment of costs and cost-effectiveness (Hollands et al., 2016;…

The Every Student Succeeds Act (ESSA) replaced the No Child Left Behind Act with great fanfare and enthusiasm. Granting more power to states and curbing what was seen as federal overreach was well received. However, the new legislation maintains a predominately test-based accountability system with a federal mandate for interventions in well over…

For the past decade, MDRC has evaluated a number of interventions designed to improve the outcomes of community college students, including enhanced counseling, learning communities, and financial incentives. Encouragingly, many of these strategies have produced positive effects, affirming that changes in institutional practices and policies can…

Enrollment is rising across the nation's community colleges, but completion rates remain untenably low. Reformers are focusing on the importance of using comprehensive, high-quality data on student progress and completion to bring about change. A core tenet of Achieving the Dream: Community Colleges Count has been to embed a culture of…

Professional development--formal in-service training to upgrade the content knowledge and pedagogical skills of teachers--is widely viewed as an important means of improving teaching and learning. While many interventions "include" professional development, professional development was the central intervention of the two recent research and…

Between 2007 and 2009, reports were released on the results of three separate large-scale random assignment studies of the effectiveness of school-based mentoring programs for youth. The studies evaluated programs implemented by Big Brothers Big Sisters of America (BBBSA) affiliates (Herrera et al., 2007), Communities In Schools of San Antonio,…

The objective of this systematic review is to summarize the available evidence on the effects of prevention and intervention programs aimed at primary and secondary students for increasing school completion or reducing school dropout. Program effects on the closely related outcomes of school attendance (absences, truancy) will also be examined.…

With more than half of children with disabilities being educated in the general education classroom, and with federal education law requiring improved learning outcomes for these students, preparing general education teachers to work effectively with all students is critical. This report on teacher certification requirements in the nine Northeast…

Compares the Schools Reaching Out programs at two elementary schools in Roxbury (MA) and New York City with four similar projects elsewhere. Describes how an intervenor not involved with the ordinary operation of the school can help design, direct, motivate, and assess a school outreach program. (DM)

The Parent Services Project (PSP) is a family resource program which provides supportive activities for highly stressed and socially isolated parents based on the "social support as a stress-buffer" model of primary prevention. A PSP evaluation followed parents as they went through the PSP program and compared them with a matched control…

The economic efficiency of alternative types of intervention was investigated with language-impaired preschool children. Forty children were assigned to one of four groups: home-based intervention, center-based intervention, both center- and home-based intervention, and no treatment. The home-based program was more economically efficient based on…

This study employs meta-analysis and cost-effectiveness instruments to evaluate and compare cross-age tutoring, computer assistance, class size reductions, and instructional time increases for their utility in improving elementary school reading and math scores. Using intervention effect studies as replication models, researchers first estimate…
