The Head Start Family and Child Experiences Survey (FACES) collects data on a nationally representative sample of Head Start programs, classrooms, teachers, parents, and children examining the quality and effects of Head Start. Three waves of data collection have occurred: in 1997, 2000, and 2003. Information presented in this publication is primarily based on the 2003 cohort, however, 1997 and 2000 data are also presented. Unless otherwise noted, the sample for the 2003 child outcomes analyses includes all 3-, 4-, and 5-year-old children who passed an English-language screener. All findings presented are statistically significant. Instruments used to collect data are presented in this paper: (1) The Peabody Picture Vocabulary Test, Third Edition (PPVT); (2) Selected scales from the Woodcock Johnson Psycho-Educational Battery (Revised); (3) Social Skills Scale; (4) Preschool Learning Behavior Scale (PLBS); (5) Problem Behaviors Scale; (6) Early Childhood Longitudinal Survey-Kindergarten Cohort (ECLS-K) Reading and General Knowledge Scales; (7) Parent Interview; (8) The Early Childhood Environment Rating Scale-Revised (ECERS-R); and (9) Classroom Activities Scale.
