This paper uses data from the Head Start Impact Study (HSIS), a nationally representative multisite randomized trial, to quantify variation in effects of Head Start during 2002-2003 on children's cognitive and socio-emotional outcomes relative to the effects of other local alternatives, including parent care. We find that (1) treatment and control…

There are unique challenges to estimating causal effects of preschool for students with special needs that have not received attention in the literature. We revisit the Head Start Impact Study (HSIS) to illustrate that when and how special needs is defined has implications for the internal validity of and interpretation of special needs subgroup…

Head Start programs currently provide early childhood education and family support services to more than 900,000 low-income children and their families across the United States with an annual budget of around $8 billion in state and federal funds.

Care Quality Rating and Improvement Systems (QRISs) have advanced and matured, a number of states and localities have undertaken evaluations to validate the systems. Such efforts stem from the desire to ensure that the system is designed and operating in the ways envisioned when the system was established. Given that a central component in a QRIS…

This is the full report, and a separate research brief also was published. Austin Independent School District (AISD) served 5,450 pre-K students in 2009-2010. Approximately 70% of sampled English-speaking pre-K students and 74% of sampled Spanish-speaking pre-K students had faster than the expected growth rate on an assessment of receptive…

Austin Independent School District provided full-day prekindergarten to 5,196 4-year-olds in 2008-2009 at 66 schools. Seventy percent or more of students made measureable gains on a test of receptive vocabulary, and average gains showed growth about two times greater than that expected for 4-year-olds after a 7-month period.

The "MTP-Math/Science" curricula specifically target the teaching and learning of children at risk of early school failure, a population for whom achievement gaps in mathematics and science are visible even in Pre-K years. "MTP-Math" is based on Focal Areas defined by the National Council of Teachers of Mathematics (NCTM)…

This paper reports the fifth-year results of a study comparing the English and Spanish language and reading performance of Spanish-dominant children randomly assigned beginning in kindergarten to Transitional Bilingual Education (TBE) or Structured English Immersion (SEI).
