Year-round school is the organization of days within a school calendar year to provide students with regular breaks and instructional blocks. This study surveyed 502 parents to identify factors influencing parental support for, or opposition to, year-round school. Three themes were constructed based on parent responses: children need educational…

Background: Research shows that over summer break, students forget approximately 1 month of learning in math and reading; furthermore, low-income students lose ground relative to peers. Year-round education (YRE) redistributes schooldays to shorten summer. Prior analyses pooled single-track YRE (academic intervention in which all students attend…

In this meta-analysis, I have reviewed published and unpublished research on single-track, year-round education's effect on science and social studies achievement, 2001-2016. Of 30 studies that met inclusion criteria and had data from which an effect size estimate could be calculated, 7 reported science outcomes (18 effect size estimates) or…

Background: Body mass index (BMI) increases when students are away on summer vacation. Evaluation of serial BMI measurements on year-round students allows new insight into the reasons children gain weight seasonally. Methods: The 206 first and second graders of 2-year-round elementary schools with obesity intervention programs were weighed and…

In the face of school crowding and fears about inequality-inducing summer learning loss, many schools have started to adopt multitrack year-round school calendars, which keep the same number of school days, but spread them more evenly across the calendar year. This change allows schools to support a larger student population by rotating which…

This study examines a mid-west elementary school transitioning from a school-within-a-school calendar, offering both year-round and traditional calendars, to a year-round only calendar. The satisfaction of teachers and families with the transition, and the factors that teachers and families consider in making a calendar selection, were examined…

This study found that students in settings with a year-round calendar statistically outperformed students with traditional calendars in a school-within-a-school setting in mathematics. The study included reading and math achievement of fifth graders in three school-within-a-school year-round elementary schools. Overall, the study made 16…

The impact of class time lengths on student achievement is a complex issue with multiple extraneous factors and without definitive answers. A major theme across many of the studies reviewed is that the amount of instructional time is not so important as how that time is spent. Key points include: (1) The commonly held conception that students in…

This study exploits a unique policy environment and a large panel dataset to evaluate the impact of school crowding on student achievement in Wake County, NC. We also estimate the effects of two education policy initiatives that are often used to address crowding: multi-track year-round calendars and mobile classrooms. We estimate a multi-level…

Using detailed longitudinal data for the state of California, this paper estimates the effect of year-round school calendars on nationally standardized test performance of traditionally disadvantaged students. The student subgroups studied in this paper are: low socioeconomic status, limited English proficiency, Hispanic and Latino, and African…

This paper examined whether year round schooling (YRS) in California had an effect upon the outcome and growth of schools' Academic Performance Index (API) scores. While many previous studies had examined the connection between YRS and academic achievement, most had lacked the statistical rigour required to provide reliable interpretations. As a…

The Optional Extended Year Program (OEYP), funded by a grant from the state, provides extended learning opportunities for students in kindergarten through grade 12 (K-12) who are at risk of academic failure. The primary focus of an OEYP is to reduce and ultimately eliminate the need for student grade-level retention by providing additional…
