A randomized experiment that measures the impact of a social policy in a sample of the population reveals whether the policy will work on average with universal application. An experiment that includes only the subset of the population that volunteers for the intervention generates narrower "proof-of-concept" evidence of whether the…

Between 2012 and 2018, the U.S. Department of Education invested nearly $350 million in 22 Comprehensive Technical Assistance (TA) Centers that operated across the nation. These Centers were charged with delivering TA that builds the capacity of state education agencies (SEAs) to support local education agencies in improving student outcomes.…

This evaluation, which focuses on the capacity-building mission of the Comprehensive Centers, was designed to add to the findings of the previous national evaluation of the Comprehensive Centers Program. That evaluation, completed in 2011, used survey data, structured interviews, and rating scales to analyze the extent to which State Education…

In experimental evaluations of health and social programs, the role of dosage is rarely explored because researchers cannot usually randomize individuals to experience varying dosage levels. Instead, such evaluations reveal the average effects of exposure to an intervention, although program exposure may vary widely. This article compares three…

Tiered evidence initiatives are an important federal strategy to incentivize and accelerate the use of rigorous evidence in planning, implementing, and assessing social service investments. The Social Innovation Fund (SIF), a program of the Corporation for National and Community Service, adopted a public-private partnership approach to tiered…

The Head Start Act mandates that each Head Start recipient receive a monitoring review at least once every 3 years; each newly designated recipient be reviewed after the completion of its first year (and then at least once every 3 years thereafter); and all recipients that "fail to meet the standards" receive Follow-up reviews. Reviewers…

The Head Start Act mandates that each Head Start grantee receive a monitoring review at least once every 3 years; each newly designated grantee be reviewed after the completion of its first year (and then at least once every 3 years thereafter); and all grantees that "fail to meet the standards" receive Follow-up reviews. Reviewers…

This case study describes the peer evaluation system the Maricopa County Educational Services Agency (MCESA) is using in the districts participating in its Teacher Incentive Fund (TIF) 3 and 4 grants. Maricopa County's TIF districts cover much of the Phoenix, Arizona, metropolitan area. Including both TIF 3 and 4 cohorts, 12 districts with a total…

This report presents a summary of the findings of fiscal year (FY) 2018 Head Start monitoring reviews, fulfilling the reporting requirement in Section 641A(f) of the Head Start Act. It highlights the enhancements made to the FY 2018 monitoring review system, summarizes grantee review outcomes, and describes the types of findings most commonly…

Upward Bound (UB) was one of the original federal "Great Society" programs of the 1960s and remains, fifty years later, the single largest college access program in the country. Recently, Congress has reduced funding and considered eliminating the program because of federal budget pressures and because the first analysis of the only…

This study examined the Workforce Investment Act (WIA) One-Stop Center model, which is the local service mechanism for providing employment and training services. It reviewed the processes and service patterns of four program designs that offer an array of services that align with the WIA program's allowable activities. The purpose of the study…

Federal social programs are rarely evaluated to determine whether they are actually accomplishing their intended purposes. As part of its obligation to spend taxpayers' dollars wisely, Congress should mandate that experimental evaluations of every federal social program be conducted. The evaluations should be large-scale, multisite studies to…

Researchers have become increasingly interested in programs' main and interaction effects of two variables (A and B, e.g., two treatment variables or one treatment variable and one moderator) on outcomes. A challenge for estimating main and interaction effects is to eliminate selection bias across A-by-B groups. I introduce Rubin's causal model to…
