The Baby FACES continues a series of ongoing descriptive studies aimed at maintaining an up-to-date, extensive knowledge base to support Early Head Start policies and programs. Building on the findings from the Survey of Early Head Start Programs, and similar in design to the Head Start Family and Child Experiences Survey (FACES), Baby FACES has five main goals: (1) Provide descriptive information about Early Head Start services offered, their frequency and intensity; (2) identify key characteristics of families currently served in Early Head Start; (3) investigate how programs individualize services to meet family needs; (4) learn how Early Head Start children and families are faring over time; and (5) explore associations between the type and quality of Early Head Start services and child and family well-being. The study employs a longitudinal cohort design that identifies a representative sample of 89 Early Head Start programs in 2009 and two cohorts of families: (1) a perinatal group, and (2) a group of infants about 1 year old. Data are collected annually, in the spring, until the sample children reach 3 years of age and complete the Early Head Start program, with a supplemental interview about transition activities with some parents when the children are 3 ½.
