Research Findings: Promoting inhibitory control in preschoolers could increase the likelihood of positive developmental trajectories. Nevertheless, to date only a limited number of studies have focused on inhibitory control training, reporting mixed results. To examine the efficacy and the transfer effects of the training on preschoolers, seven…

Although pre-K students' average gains on the 2010-2011 Peabody Picture Vocabulary Test (PPVT in English, TVIP in Spanish) significantly differed by vertical team, these differences were attributed more to the students' school or classroom rather than to the vertical team in which a school resided. [For "Prekindergarten Evaluation Series,…

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…

We evaluated the effectiveness of a two-generation preschool programme (centre-based early childhood education, parenting education and family support) on receptive language skills in children living in culturally diverse families with low income. Using a with-in subject pre-test/post-test design, children (N = 112) showed a statistically…

Although more than a third of tested pre-K students (37%) entered AISD one standard deviation below the national average in receptive vocabulary, the AISD pre-K program accelerated these students' growth by nearly twice the national average by the end of the 2010-2011 school year.

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). This is the first randomized study to compare TBE and SEI reading…

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…

The purpose of this study was to examine the short-term effects of a music education intervention on the receptive language skills of students in an at-risk early childhood program. The target population was nine students ages 3, 4, and 5 in an at-risk, inclusive classroom in a Chicago public school. The problem of language delay is indicated in…

The prekindergarten (pre-K) program is an important part of the systemic effort by the Austin Independent School District, Texas (AISD) to help every student meet the state's student performance standards. In 2000-2001, 41 of the district's schools offering pre-K (79% of all elementary schools) had full-day programs and 17 had half-day programs. A…

The Austin Independent School District (AISD) prekindergarten program is an important component of the state and district goal of having every student reading on grade level by the end of third grade. In 1999-2000, 57 of the 71 AISD elementary schools provided prekindergarten education. The AISD prekindergarten program served 3,571 4-year-olds.…

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.

To reemphasize the dangers inherent in the misuse of testing instruments, a study of language and cognitive development in poverty preschoolers investigated 1) whether the interpretation of Peabody scores could be applied to this population, and 2) the contribution of the linguistic form of the Peabody to performance.
