Older schoolchildren typically perform better on academic achievement tests than younger students in the same classes. Studies looking at an array of countries, grade spans, and subjects have found that age differences of even a few months do matter. Relative-age effects introduce an arbitrary bias that favors older students. These effects are a…

Adolescents across the United States, in general, do not get enough sleep. This is often the result of early school start times. When children reach adolescence, a biological change occurs, causing their circadian cycle to delay and resisting the build-up of homeostatic pressure. Consequently, adolescents have difficulties falling asleep earlier…

Each year, the Houston Independent School District (HISD) offers a summer education program designed to assist students with a variety of instructional needs. Centrally coordinated summer school programs in 2019 included accelerated instruction for State of Texas Assessments of Academic Readiness (STAAR) and STAAR End-of-Course (EOC) re-testers;…

A comparison of Chicago public school students' standardized test scores in 2009-2014 with those of public students across the U.S. reveals two striking patterns. First, Chicago students' scores improved dramatically more, on average, between third and eighth grade than those of the average student in the U.S. This is true for students of all…

Multiple studies propose that English proficiency dictates English language learners' (ELLs) performances on mathematics assessments. The current study investigates the predictive power of English proficiency on mathematics scores, while controlling for gender, socioeconomic status (SES), and grade level among ELLs at a south Florida elementary…

The purpose of this study was to examine the relationship between the type of grade configuration and racial climate of a school on the academic performance and discipline of middle school aged students. Specifically, this study was concerned with the predictive power of the type of grade configuration (stand-alone middle school vs. non-transition…

This report looks at student growth in Arkansas school districts disaggregated by district poverty and by the district's value-added performance relative to other districts. We estimated district value-added performance statistics by subject and grade level (8 and 11-12) for longitudinal student cohorts, using statistical models that adjusted for…

The main aim of this study was to develop standardised tests that assess some of the most important spelling skills for children in primary school: sound-letter mappings (non-lexical spelling) and word spelling accuracy (lexical spelling). We present normative comparison data for children in Grades 1-7 as well as measures of validity and…

This annual report provides information for the 2012-13 school year on grade-level retention and student performance in the Texas public school system. Student retention and promotion data are reported with data on the performance of students in Grades 3-8 on the State of Texas Assessments of Academic Readiness (STAAR) reading and mathematics…

This report examines the patterns of placement of Teach for America (TFA) teachers and the achievement of the students they taught during the 2017-18 school year. The length of time current and former TFA teachers continue as employees of the District is also explored. TFA is an organization that recruits recent college graduates/professionals to…

We study the effectiveness of teachers certified by the National Board for Professional Teaching Standards (NBPTS) in Washington State, which has one of the largest populations of National Board Certified Teachers (NBCTs) in the nation. Based on value-added models in math and reading, we find that NBPTS certified teachers are about 0.01-0.05…

This dissertation uses data from the evaluation of a Striving Readers project to examine the associations between levels of implementation of different components of Scholastic's "READ 180" and student achievement as measured on the Iowa Test of Basic Skills (ITBS) reading assessment. The approach was hierarchical linear modeling using…

Purpose: The purpose of this study was to examine the role of teacher characteristics and school demographics in teachers' perceptions of children's cognitive abilities. Most researchers find that teachers' personal characteristics are not related to their perceptions of their children's cognitive abilities. In a 2011 study, Douglas Ready and…
