How Do Linguistically Diverse Students Fare in Full- and Half-Day Kindergarten? Examining Academic Achievement, Instructional Quality, and Attendance

Abstract

Research Findings: This study investigated the effects of full- and half-day kindergarten programs on classroom instructional quality and children's academic achievement. Considerations were given for how the length of the school day, language status (English language learner [ELL] and non-ELL), and children's attendance patterns influenced achievement. Quantitative and qualitative data were collected concurrently and were interpreted to note the convergence (or lack thereof) of the findings. Quantitative results revealed no difference in the quality of instruction being offered in full- and half-day classrooms. Additionally, full-day kindergarten positively impacted children's academic achievement in literacy but not in mathematics, regardless of children's language status. In regard to language development, ELL children benefited more from full-day kindergarten than did their English-speaking peers, whereas all (ELL and non-ELL) children enrolled in full-day kindergarten made greater language gains when they missed fewer than 10 school days. Practice or Policy: Findings from this study have significant policy and practice implications related to the overall quality, availability, and cultural and developmental appropriateness of kindergarten programming in the United States.
