The goal of the study is to examine the strengths and weaknesses of the approach and present them in ways that are broadly accessible to applied quantitative social scientists.
The Impact of Supplemental Literacy Courses for Struggling Ninth-Grade Readers
Over the course of ninth grade, two supplemental literacy courses modestly improved students’ reading comprehension skills and helped them perform better academically in their course work. However, these benefits did not persist in the following school year, when students were no longer receiving the supplemental support.
Reemployment Strategies in Retention and Advancement Programs for Current and Former Welfare Recipients
When current and former welfare recipients find jobs, they often lose them quickly and have trouble finding another job. This brief, based on the experiences of 12 programs in the national Employment Retention and Advancement evaluation, offers advice on how to design and implement practices that turn a recent job loss into an opportunity to find a better one.
This final report of a two-year evaluation is intended to help states determine how to structure child care subsidy programs. Focusing on how much families should be required to contribute when they receive child care subsidies, the study examined the effects of reduced copayments on subsidy use, employment and earnings, and receipt of public assistance.
How Much Do Achieving the Dream Colleges Spend — and from What Resources — to Become Data-Driven Institutions?
This report analyzes the experiences of five community colleges that participate in Lumina Foundation’s Achieving the Dream initiative and the investments they made in implementing an institutional improvement process aimed at increasing students’ success. The report examines how, where, and with what resources these colleges supported their reforms, as well as the key activities driving their overall expenditures.
A random assignment study of learning communities that linked a developmental reading course and a “college success” course finds that faculty collaboration and curricular integration increased over time. Overall, the program had no impact on students’ academic success, but evidence suggests that it had some positive effects for the last cohort of students in the study.
How New York City’s New Small Schools Are Boosting Student Achievement and Graduation Rates
Taking advantage of lottery-like features in New York City’s high school admissions process, this study provides rigorous evidence that new small public high schools are narrowing the educational attainment gap and markedly improve graduation prospects, particularly for disadvantaged students.
This report examines the financial benefits and costs of three different programs in the national Employment Retention and Advancement project, sponsored by the federal Administration for Children and Families, that have increased employment and earnings among current and former welfare recipients.
Interim Results of the National Guard Youth ChalleNGe Evaluation
Interim results from a random assignment evaluation of the National Guard Youth ChalleNGe Program, an intensive, residential program for high school dropouts, show that young people who had access to ChalleNGe were much more likely than those in the control group to have obtained a high school diploma or a General Educational Development certificate. They were also somewhat more likely to be working, in college, or enlisted in the military.
In some experimental evaluations of classroom- or school-level interventions, random assignment is conducted at the student level and the program is delivered at the higher level. This paper clarifies the correct causal interpretation of “program impacts” when this study design is used and discusses the implications and limitations of this research design. A real example is used to demonstrate the paper’s key points.
This report presents first-year results from the Middle School Mathematics Professional Development Impact Study, sponsored by the Institute of Education Sciences. The professional development programs for seventh-grade math teachers had an impact on one measure of teacher practice but no effects on teachers’ knowledge or student achievement.
This report presents the final implementation and impact findings for 12 programs in the national Employment Retention and Advancement project, sponsored by the federal Administration for Children and Families. These programs attempted to promote steady work and career advancement for current and former welfare recipients and other low-wage workers, most of whom were single mothers.
This working paper, prepared for a conference sponsored by the Institute for Research on Poverty at the University of Wisconsin-Madison, reviews evidence about the effectiveness of two strategies to strengthen family relationships and fathers’ involvement with their children: fatherhood programs aimed at disadvantaged noncustodial fathers and relationship skills programs for parents who are together.
Six-Month Results from the Accelerated Benefits Demonstration
This policy brief offers early findings from a demonstration testing whether earlier access to health care and related services for new Social Security Disability Insurance (SSDI) beneficiaries who lack health care coverage would lead to improved outcomes. So far, the intervention has increased the use of health care services and reduced the reported unmet health care needs of the project participants.
The Policy and Practice of Assessing and Placing Students in Developmental Education Courses
This paper reports on case studies conducted at three community colleges to learn about how the colleges assess students for placement in developmental education courses. The case studies identify several problems and challenges, including lack of consensus about the standard for college-level work, the high-stakes nature of the assessments, and the minimal relationship between assessment for placement and diagnosis for instruction.
Learning communities, which enroll groups of students together in coordinated classes, are increasingly being used to help developmental-level students succeed. This report on the Learning Communities Demonstration, a large-scale, random assignment evaluation, describes the strategies that six community colleges used and the challenges they faced in scaling up their programs.
Early Findings from New York City’s Conditional Cash Transfer Program
Targeted toward low-income families in six high-poverty New York City communities, Opportunity NYC-Family Rewards offers cash payments tied to efforts and achievements in children’s education, family preventive health care practices, and parents’ employment. In its first two years, the program substantially reduced poverty and material hardship and had positive results in improving some education, health-related, and work-related outcomes.
The Youth Transition Demonstration, led by Mathematica Policy Research, MDRC, and TransCen, Inc., is developing and evaluating promising strategies to help youth with disabilities become as economically self-sufficient as possible as they transition from school to work. This report offers six overall implementation lessons to help policymakers and administrators develop, fund, and provide interventions for youth with disabilities.
