Across 25 studies that met inclusion criteria, study samples consisted primarily of Latino or Spanish-speaking children 3–5 years of age enrolled in center-based programs. The analysis focused on features of the early education programs and practices (intensity and language of instruction) and research methods (sampling, research designs) in relation to child outcomes for the various types of research interventions evaluated in these studies (center-based programs, professional development, curricula, and instructional strategies). On the basis of a few large- scale scientifically sound studies, the review found at least some evidence to suggest that DLLs benefitted from attending widely available, well regulated programs such as Head Start and public pre-k, particularly with respect to improving language and literacy skills. However, because the extant research has not systematically accounted for the separate effects of language of instruction versus type of intervention, very little can be concluded about how these factors contribute to the positive main effects of these interventions. © 2013 Elsevier Inc.
