International assessments inform education policy debates, yet little is known about their floor effects: To what extent do they fail to differentiate between the lowest performers, and what are the implications of this? TIMSS, SACMEQ, and LLECE data are analyzed to answer this question. In TIMSS, floor effects have been reduced through the…

Researchers have long postulated the existence of a big-fish-little-pond effect (BFLPE) in which a student's relative academic standing in class or school affects his or her academic self-concept. Few studies, however, use causal research designs to identify whether the BFLPE exists and whether it is generalizable across a wide variety of…

This article considers the growth of the international testing regime. It discusses sources of growth and empirically examines two related sets of issues: (1) the stability of countries' achievement scores, and (2) the influence of those national scores on subsequent economic development over different time lags. The article suggests that…

Adolescent girls more often than boys expect higher education in nearly all 50 education systems in TIMSS 2011, before and after controls for effects of educational achievement, education-conducive family resources, and "liking school." At a macrolevel, this gender disparity is moderately correlated with the gender disparity in…

Expanding numbers of researchers are focusing on the scale and impact of private supplementary tutoring. Such tutoring is widely called shadow education, since much of its curriculum mimics that of regular schooling. Although shadow education has expanded significantly worldwide and is now recognized to have far-reaching significance, research…

Most existing research indicates that working students perform more poorly than do full-time students on standardized achievement tests. However, we know there are wide international variations in this gap. This article shows that national and international contexts help to explain the gap in the academic performance between working and nonworking…

As more primary and secondary students worldwide seek after-school tutoring in academic subjects, concerns are being raised about whether after-school tutoring can raise average test scores without widening the variability in student performance, and whether students of certain ability levels may benefit more than others from after-school…

In international achievement studies, questionnaires typically ask about the presence of particular household assets in students' homes. Responses to the assets questions are used to compute a total score, which is intended to represent household wealth in models of test performance. This study uses item analysis and confirmatory factor analysis…

Based on 1970s data, the "Heyneman-Loxley (HL) effect" proposed that in developing nations, school variables were more important than family socioeconomic status in determining academic achievement. A reassessment of the HL effect using 1990s TIMSS data found the relationship between family background and student achievement to be…
