Approximately 5,000 newly entering 3- and 4-year- old children applying for Head Start were randomly assigned to either a Head Start group that had access to Head Start program services or to a non- Head Start group that could enroll in available community non-Head Start services, selected by their parents. Data collection began in fall 2002 and is scheduled to continue through 2006, following children through the spring of their 1 st -grade year. The study quantifies the impact of Head Start separately for 3- and 4-year- old children across child cognitive, social-emotional, and health domains as well as Exhibit 1: Summary of Main Impact Findings 1 Effect Sizes 2 Domains, Constructs, and Measures 3-Year-Old 4-Year-Old Group Group Cognitive Domain Pre-Reading Woodcock-Johnson III Letter-Word Identification 0.24 0.22 Letter Naming 0.19 0.24 Pre-Writing McCarthy Draw-A-Design 0.13 Woodcock-Johnson III Spelling 0.16 Vocabulary PPVT-III Adapted 0.12 Color Naming 0.10 Parent Reported Literacy Skills 0.34 0.29 Oral Comprehension and Phonological Awareness Early Math Social-Emotional Domain Problem Behaviors Total Behavior Problems -0.13 3 Hyperactive Behavior -0.18 3 Aggressive Behavior Withdrawn Behavior Social Skills and Approaches to Learning Social Competencies Health Domain Access to Health Care Child Had Dental Care 0.34 0.32 Child Has Health Insurance Health Status Overall Health Status 0.12 Child Needs Ongoing Care Child Had Care for Injury Parenting Domain Educational Activities Number of Times Child Read To 0.18 0.13 Family Cultural Enrichment Scale 0.11 Discipline Strategies Spanked Child in Last Week -0.14 3 Number of Times Spanked -0.10 3 Used Timeout Number of Timeouts Child Safety Practices Overall Parental Safety Practices Removing Harmful Objects Restricting Child Movement Safety Devices 1 All effect sizes presented in table are based on statistically significant treatment and control differences of at least p 0.05. 2 Effect sizes relate the magnitude of impacts to the variation of the outcome as measured by the estimated treatment and control differences relative to the magnitude of the standard deviation on the measure of interest (i.e., as a fraction of one standard deviation). 3 Negative effect sizes mean reduction in total problem behaviors, hyperactive behavior, and spanking. i
