This article proposes a latent variable regression four-level hierarchical model (LVR-HM4) that uses a fully Bayesian approach. Using multisite multiple-cohort longitudinal data, for example, annual assessment scores over grades for students who are nested within cohorts within schools, the LVR-HM4 attempts to simultaneously model two types of…

The present paper aims to discuss how data from international large-scale assessments (ILSAs) can be utilized and combined, even with other existing data sources, in order to monitor educational outcomes and study the effectiveness of educational systems. We consider different purposes of linking data, namely, extending outcomes measures,…

In a 5-year longitudinal study of typical literacy development (Grades 1-5 or 3-7), relationships were examined between (a) parental responses to questionnaires about home literacy activities and ratings of children's self-regulation at home, both completed annually by the same parent, and (b) children's reading and writing achievement assessed…

Background: Little is known about the nature, range and prevalence of different subgroups in language trajectories extant in a population from 4 to 11 years. This hinders strategic targeting and design of interventions, particularly targeting those whose difficulties will likely persist. Methods: Children's language abilities from 4 to 11 years…

Above-level testing is the practice of administering aptitude or academic achievement tests that are designed for typical students in higher grades or older age-groups to gifted or high-achieving students. Although widely accepted in gifted education, above-level testing has not been subject to careful psychometric scrutiny. In this study, I…

High School, Aptitude and Achievement Tests have been utilized since 2002 in Saudi Arabia for the purpose of student selection to health sciences and medical colleges. However, longitudinal studies determining the predictive validity of these so-called cognitive tests for in-course performance is lacking. Our aim was to assess the predictive…

The experimental evaluation of the "Tools of the Mind Pre-K Curriculum" described in this report was designed to examine the effectiveness of the "Tools of the Mind" ("Tools") curriculum for enhancing children's self-regulation skills and their academic preparation for kindergarten when compared to the usual…

We examined the persistence of teacher effects from grade to grade on lower-performing students using data from Project STAR. Teacher effects were computed as residual classroom achievement within schools. Teacher effects in one grade predicted achievement in following grades using quantile regression. Results consistently indicated that all…

This report focuses on the extent to which students who are academically far off track in fourth or eighth grade in Kentucky catch up by eighth or eleventh grade. We studied three recent cohorts of Kentucky students whose eighth-grade ACT Explore® scores were more than one standard deviation below the ACT Explore benchmark scores associated with…

Background/Context: This article addresses the classroom contextual effects of absences on student achievement. Previous research on peer effects has predominantly focused on peer socioeconomic status or classroom academic ability and its effects on classmates. However, the field has been limited by not discerning the individual-level academic…

The purpose of this research is to study the long-run impacts (i.e. on educational attainment) of a freshman math intervention called "double-dose algebra". The intervention was conducted in 2003 and 2004 within the Chicago Public Schools (CPS), a large, poor urban school district. In response to low passing rates in 9th grade algebra,…

The stability of annual normal curve equivalent (NCE) on the Iowa Test of Basic Skills over a period of six years was established in a previous study of status (position within a reference group). This study investigated the relationship between status stability and student achievement level. Third grade students in a suburban school district who…

The study analyzes the achievement trends of all third grade students in the state of Illinois who scored in the Exceeds category in reading and mathematics on the Illinois Standards Achievement Test (ISAT) in the year 2000. ISAT performance of this cohort group of students was followed through the eighth grade. Descriptive analyses were utilized…

The Educational Testing Service (ETS) was contracted by the National Center for Education Statistics to investigate changes in tested achievement using cross-sectional comparisons between the 1972 National Longitudinal Study (NLS) seniors and the 1980 High School and Beyond (HSB) senior cohort. The ETS is also responsible for estimating the extent…

Academic achievement under a four-day school week is compared to the traditional five-day school week. Test scores from the CAT [California Achievement Test], ITBS [Iowa Test of Basic Skills], TASK [Stanford Test of Academic Skills], SAT [Stanford Achievement Test], TAP [Tests of Academic Proficiency], and MAT [Metropolitan Achievement Test] were…
