The present study examined the relationships between the standardized applied behavior analysis (ABA) direct assessment, the PEAK Comprehensive Assessment (PCA), and established assessments commonly used in educational and clinical settings, including the Childhood Autism Rating Scale - Third Edition (CARS-3), the PDD Behavior Inventory (PDDBI),…

Background: The Early Learning Outcomes Measure (ELOM) assesses early learning programme outcomes in children aged 50-69 months. ELOM assesses gross motor development (GMD), fine motor coordination and visual motor integration (FMC & VMI), emergent numeracy and mathematics (ENM), cognition and executive functioning (CEF), and emergent literacy…

This study further examined the Gifted Rating Scales (GRS) at the internal and external stages of test validation by (a) testing structural fidelity as indicated by the number of factors supported as well as the correspondence of the latent factor structure with the scoring model proposed by the authors and (b) examining the external relations of…

Many global settings lack indigenous measures of child development, making the adaptation of available instruments necessary. The aim of this study was to reliably adapt the core subtests of the Wechsler Preschool and Primary Scale of Intelligence-III (WPPSI-III) to assess cognitive abilities in young children in rural Pakistan. A systematic…

The Sustainable Development Goals mandate that by 2030, all children should have access to quality early child development opportunities, healthcare and pre-primary education. Yet validated measures of ECD in low and middle income countries (LMICs) are rare. To address this gap, a Systematic Review (SR) of measures available to profile the…

This study describes the reliability and validity of four language tests: The Sentence Comprehension Test (SCT), the Expressive Language Test (ELT), the Sentence Repetition Test (SRT), and the Arabic Picture Vocabulary Test (APVT). These tests were administered to two groups of Qatari Arabic-speaking children: A typically developing group (n=81 to…

Universal screening of very early school-age children (age 4-7 years) is important for early identification of learning problems that may require enhanced learning opportunity. In this context, use of standardized instruments is critical to obtain valid, reliable, and comparable assessment outcomes. A wide variety of standardized instruments is…

This study tested whether individual executive function (EF) tasks were better characterized as formative or reflective indicators of the latent construct of EF. EF data that were collected as part of the Family Life Project (FLP), a prospective longitudinal study of families who were recruited at the birth of a new child (N = 1,292), when…

The study compared differences and similarities between WISC and WISC-R scores for 48 ten- and thirteen-year-old educable mentally retarded students, who were matched according to sex and race. Results suggest that many children classified as "Borderline" or slightly above the WISC will be classified as "Mentally Deficient" by…

Attention is drawn to the ways in which current conceptions of intelligence and its measurement differ from those which were generally accepted in 1928. The following principles underlying intelligence testing were generally agreed upon in 1928: (1) the assumption of intelligence as a recognizable attribute, responsible for differences among…

The practice of cognitive referencing to determine the presence of a specific language impairment (SLI) and eligibility for services is questioned by a study which compared the variability of the IQ scores of children with specific language impairment over time. The study found high IQ variability, suggesting that IQs reflect current abilities…

In educational research and evaluation, a sample of subjects usually received some type of programmatic treatment. Outcome scores for these students are then compared with outcome scores of a control or comparison group. M. Lewis and H. McGurk (1972) have pointed out that there are some implicit assumptions when this approach is applied to…

Recent efforts have been made to develop more age-appropriate intelligence measures for the elderly to determine the nature of age differences and changes in adult cognitive development. Spatial and reasoning performances of young, young-old and old-old individuals were compared on traditional versus familiar and presumably more meaningful…

This study was designed to determine what happens to the intelligence quotient of freshman students during their enrollment at a private Negro college. The Otis Quick-Scoring Mental Ability Test, Gamma Em, was administered to 822 students from a population of approximately 2,000 in their freshman year at Hampton Institue, Hampton, Virginia. The…

The Analogical Reasoning Learning Test (ARLT) was developed for use with individuals with IQs lower than 55. A study involving 58 students (ages 6-19) with moderate to severe mental retardation found the internal consistency and test-retest reliability of this measure are high. Discriminant and predictive validity are satisfactory. (Contains…
