Little is known about the characteristics of academic overachievers, children whose achievement significantly exceeds IQ. Correlates of overachievement (achievement test scores = 1 SD above IQ), nondiscrepant achievement, and learning disability (LD; achievement = 1 SD below IQ) were analyzed in 1,543 children (739 ADHD, 285 autism, and 519…

Using quantile regression analyses, this study examines gender gaps in mathematics, science, and reading in Azerbaijan, Indonesia, Jordan, the Kyrgyz Republic, Qatar, Tunisia, and Turkey among 15-year-old students. The analyses show that girls in Azerbaijan achieve as well as boys in mathematics and science and overachieve in reading. In Jordan,…

The main purpose of this study was to examine the classroom, teacher and student factors distinguishing grade three classes performing at higher levels than expected, in relation to socioeconomic status (SES) and language factors, from classes performing below their potential with regard to the same factors. Data from a standardized reading…

The main objective of this study was to explore how teachers and classroom factors contribute to students' successful literacy learning. Eight Grade three classes, achieving at higher levels than expected with regard to socio-economic background and language factors, were identified in a multicultural Stockholm district and statistically…

This paper sets out to give some empirical findings on the distributions of over- and under-achievement in reading in order to order to provide a factual base from which conceptual arguments may start. (Author)

This investigation was designed to explore the differences between 6th grade underachievers, average achievers, and overachievers in reading in their later achievement and behavior and to compare relationships to reading achievement that occur for students with high socio-economic status (SES) background and low SES background, and students with…

Delineated characteristics of over- and under-achievers within a sample of 372 randomly selected public school students aged 6 through 17 years from 3 racial-ethnic groups and 2 levels of socioeconomic status. Found discrepant achievement not to be unique to particular race, intelligence, gender, age, family size, or degree of family intactness.…

Presented is a procedure that could be used by a school system to identify by the end of first grade those children who are likely to underachieve (achieve or overachieve) in reading by the third grade. The procedure consists of (1) Defining underachievers, achievers, and overachievers through use of regression and its standard error, (2)…

The distribution of measured reading achievement in a population of 3,651 sixth-grade students and the relationship of reading deficiency to later achievement and behavior in secondary schools were reported. Reading deficiency was defined as a discrepancy between the level of reading ability expected on the basis of a subject's total mental…

SCORES FROM 16 VARIABLES WERE USED TO ASSESS DIFFERENCES AMONG 194 JUNIOR HIGH SCHOOL BOYS AND GIRLS OF 4 TEXAS COMMUNITIES WHO WERE AMONG MORE THAN 1,500 PUPILS INCLUDED IN THE "TEXAS HUMAN TALENT PROJECT." SUBJECTS WERE CLASSIFIED INTO "UP,""DOWN," OR "STABLE" SAMPLES. CLASSIFICATION INTO THE…

Highlights a National Assessment of Educational Progress study indicating that in the 1970s academic gains in reading by some low achievers was offset by declines in science and math skills of high achievers. Additional results related to reading, science, and mathematics are also highlighted and discussed. (JN)
