The U.S. Department of Agriculture mandates that the Supplemental Nutrition Assistance Program--Education, known as CalFresh Healthy Living (CFHL) in California, implements obesity prevention efforts that utilize…

Objective: To determine the impact of a new food scholarship program on nutrient intake and dietary quality. Participants: College students (n = 49), female (78%), single (76%), average age 28 years, and white (49%). Methods: Fruits, vegetables, dairy, meat products and nonperishable foods were distributed twice a month. A one-group pretest…

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…

Every child deserves access to a quality education, and teaching is a core determinant of students' educational experience. Quality teaching is correlated with better learning outcomes, increased student achievement, and higher salaries and other benefits in adulthood. In this report, the Center for American Progress proposes a new federal…

Background: We tested the effectiveness of the Go Wild With Fruits and Veggies! (GWWFV) Extension curriculum on increasing fruit and vegetable (FV) intake of third graders. Methods: An intervention study was used testing self-reported FV intake pre/post GWWFV. Recruited schools were randomized to control (12 schools, N = 369, third grade children)…

This report is an evaluation of the Investing in Innovation (i3) program, a tiered-evidence grantmaking initiative at the U.S. Department of Education. The program's primary purpose is to support the development, testing, and scaling of field-initiated programs for high-need students in K-12 education. This report reviews the program's early…

The National Institute of Justice (NIJ) developed the Comprehensive School Safety Initiative in consultation with federal partners and Congress. It is a research-focused initiative designed to increase the safety of schools nationwide through the development of knowledge regarding the most effective and sustainable school safety interventions and…

Preschool parent interventions may produce downstream benefits if initial intervention gains are sustained and improve later socialization experiences. This study explored associations between initial effects of the REDI (Research-based Developmentally Informed) Parent program and later benefits. A randomized trial involving 200 Head Start…

The purpose of this demonstration was to evaluate a universal intervention during teacher-identified routines that were characterized by significant classwide problem behavior. Six Head Start classrooms (seven groups of children, with one classroom divided into two groups) received two workshops and two coaching sessions on universal Positive…

Major federal education initiatives, including the No Child Left Behind Act of 2001, have highlighted the importance of teacher quality in improving student achievement. The federal government has committed significant funding and resources to professional development programs for teachers through Title II of the Act and other initiatives. There…

Sixty-four federal Elementary and Secondary School Counseling (ESSC) program grants were awarded in 2009. One awarded school district implemented a comprehensive school counseling program based on the ASCA National Model at three high-needs elementary schools. This case study describes a district initiative that provided prevention education for…

Recent congressional initiatives seek to focus funds for certain federal social programs on interventions for which randomized experiments show sizable, sustained benefits to participants or society. The private, nonprofit Coalition for Evidence-Based Policy undertook the Top Tier Evidence initiative to help federal programs identify interventions…

In 2009, the federal government committed over $3 billion nationwide to help states and districts turn around their worst-performing schools. The U.S. Department of Education intended for the School Improvement Grants (SIGs) to spur dramatic change.This report looks at the results of a field study of the first-year implementation of those grants…

This study describes the results of an evaluation of the Individualized Learning Intervention, a mentoring program for early childhood educators. This mentoring program includes 3 components: Mentor Teacher Seminar, Mentor teachers supporting professional development of Protege teachers throughout the school year, and Mentor coordinator meetings…

This article examines the power analyses for the first wave of group-randomized trials funded by the Institute of Education Sciences. Specifically, it assesses the precision and technical accuracy of the studies. The authors identified the appropriate experimental design and estimated the minimum detectable standardized effect size (MDES) for each…
