Simple mean differences summarized in meta-analyses do not always adequately describe sex similarities and differences. We investigated sex similarities and differences in academic achievement test scores during childhood and adolescence multiple ways based on composite and subtest scores from the Kaufman Test of Educational Achievement (Third…

Cognitive ability and spelling predictors of written expression were examined between gender groups as well as across age and writing skill levels using quantile regression with the Kaufman Assessment Battery for Children--Second Edition and the Kaufman Test of Educational Achievement--Second Edition conormed standardization sample data (N =…

Students who exhibit giftedness alongside a learning disability (GLD) often display asynchronous academic development, and a combination of strengths that mask areas of struggle. Early identification and intervention may offset students experiencing low self-confidence and motivation, ineffective self-efficacy, or a loss of love for learning…

This study investigated developmental gender differences in mathematics achievement, using the child and adolescent portion (ages 6-19 years) of the Kaufman Test of Educational Achievement-Third Edition (KTEA-3). Participants were divided into two age categories: 6 to 11 and 12 to 19. Error categories within the Math Concepts & Applications…

Helping young children become proficient readers is a critical goal. Research tells us that students who experience difficulty reading in the early years of school often struggle to catch up (Stanley, Petscher, & Catts, 2018; Ozernov, Palchik et al., 2016; Cunningham & Stanovich, 1997; Francis, Shaywitz, Stuebing, Shaywitz, & Fletcher,…

The purpose of this study was to investigate developmental gender differences in academic achievement areas, with the primary focus on writing, using the child and adolescent portion (ages 6-21 years) of the "Kaufman Test of Educational Achievement-Second Edition, Brief Form," norming sample (N = 1,574). Path analytic models with gender,…

Using longitudinal data from 750 Mexican and Dominican American families, this study examined a cultural model of parenting and early academic achievement. While Latino…

Recent research has established a connection between children's fine motor skills and their academic performance. Previous research has focused on fine motor skills measured prior to elementary school, while the present sample included children ages 5-18 years old, making it possible to examine whether this link remains relevant throughout…

The purpose of this study was to explore the link between speech and reading to oneself among struggling readers in secondary schools.
