In Texas, the adoption of a four-day school week (4dsw) calendar from a five-day school week (5dsw) has not been widespread until recent years, but has grown significantly to 40 districts post-COVID through the 2022-23 school year. This report presents findings of an analysis of State of Texas Assessments of Academic Readiness (STAAR®) performance…

Ever since the 1983 landmark study, "A Nation at Risk", was released, educators have been examining the effectiveness of instructional time in American schools (Pedersen, 2012). However, school calendars have remained stagnant and seemingly a product of society and economy, tied to agriculture, for over 100 years (Turner & Finch,…

To achieve the goal of 100% proficiency for all students in mathematics, a middle school in a large urban public school district in Omaha, Nebraska increased the frequency of instructional time in mathematics instruction for a group of seventh and eighth grade students. The purpose of this study was to determine if there was a difference in the…

Background: Four-day school week (FDSW) use has increased substantially among US districts in recent years, but limited data exist on health impacts of this school schedule. This study examined associations of reduced school exposure via FDSWs with adolescent health and risk behaviors, obesity, and food security. Methods: Self-report data from…

The purpose for this correlational, explanatory study was to explain the influence of the length of the school day on the mean Partnership for Assessment of Readiness for College and Careers (PARCC) scores on the 2016 Grade 8 Mathematics and 2016 Algebra II tests for students in various socioeconomic strata. The Grade 8 Mathematics sample included…

Background: There have been repeated calls for more widespread use of inquiry-oriented science instruction in K-12 education. At the same time, questions have been raised regarding whether the amount of time in school schedules for science instruction is sufficient to support inquiry-based teaching. This study investigates the relationship between…

Research shows a math achievement gap for at-risk and economically-disadvantaged students in the United States. To address this issue, a Texas school district implemented a 90-minute math block-scheduling program with 8th grade students. Shaped by the academic learning time and social justice theories, the purpose of this quantitative program…

Instructional time is a fundamental educational input, yet we have little causal evidence about the effect of longer school days on student achievement. This paper uses a sharp regression discontinuity design to estimate the effects of lengthening the school day for low-performing schools in Florida by exploiting an administrative cutoff for…

The purpose for this correlational, cross-sectional, explanatory was to explain the influence of the length of the school day on the total percentage of students who scored Proficient or Advanced Proficient (TPAP) on the New Jersey Ask (NJ ASK) in Language Arts and Mathematics in Grades 6-8 in for student populations with low, median, and high…

The purpose of this study is to discuss student and school factors, including cross level interaction, that cause inequalities in seven and eighth grade students' achievement in Turkish context by using national achievement test scores with a multi-level statistical approach. Our results are in line with most other studies with similar purpose.…

Part of the Stanford Center for Opportunity Policy in Education (SCOPE) research series titled "Teachers' Time: Collaborating for Learning, Teaching, and Leading," this case study looks at the Santa Monica Alternative School House (SMASH), a K-8 public school in the Santa Monica-Malibu Unified School District (SMMUSD). It is a school of…

In 2007 Georgia instituted a flexibility policy through which school districts enter into performance contracts with the state, receiving waivers from state rules, provisions, and guidelines in exchange for agreeing to meet annual accountability targets. The performance contracts are intended to incentivize innovations that increase achievement…

These are the appendixes for the report, "District Changes in Student Achievement and Local Practice under Georgia's District and School Flexibility Policy." Five appendixes are included in the document: (1) About the study; (2) Data and methods; (3) Supporting analysis; (4) Survey instrument; and (5) Interview protocol. [For the full…

Due to budget shortfalls, teacher furloughs were imposed in 2009 in Hawaii Public Schools. The furloughs resulted in a 2009-2010 school year of 167 days as opposed to the regular school year of 180 days. The purpose of this causal-comparative study with a pretest-posttest design was to examine the found effects of those furloughs on academic…

Understanding the developmental responsiveness of secondary school environments may be an important factor in supporting students as they make the transition from one school to the next. Students' needs may or may not be met depending on the nature of the fit between their basic and developmental needs and secondary school structures at the middle…
