Learning disabled, emotionally disturbed, and unclassified male students originally tested with the Elizur Test of Psycho-Organicity (ETPO) when they were 6 to 11 years of age (time 1), were reassessed four years later (time 2) with the same instrument. Examinees were required to duplicate geometric and colored block designs, and to memorize five…

The Battelle Developmental Inventory (BDI) was administered to 121 young children, and parents rated them with the Social Skills Rating System 2-3 years after entry into the study. Correlations between the two measures revealed very weak to modest relationships, providing limited support for the BDI as a predictive measure of future…

The Slosson Intelligence Test (SIT) and the Stanford-Binet, Fourth Edition (SBIV) were administered to 95 elementary students referred because of either learning problems or potential giftedness. SIT scores predicted SBIV verbal scores more accurately than composite scores. Overall the SIT predicted SBIV scores better for students with learning…

The paper reports on a 1 year followup study to establish the short term predictive validity of an early identification system used in London, Ontario (Canada) for kindergarten and first grade high risk students. Ratings of the students by the evaluation teams in January were compared with the students' actual placements as of the following…

To identify classroom behaviors that differentiate primary-level students with learning disabilities (LD) from their nondisabled peers, two scales of 83 items each were devised and piloted. Two subscales and 18 individual items were found to discriminate students later classified as LD and those referred but not subsequently classified as LD.…

The concurrent validity of three types of reading ability assessments was evaluated with 312 Australian primary-level children. Results suggest that the nature of the skills required for success in reading changes in the primary years, and that both teacher-based and test-based assessments concur more closely as children progress through the…

The study reported here sought to establish the predictive validity of the Miller Assessment for Preschoolers (MAP), an instrument designed to identify preschool children at risk for school-related problems in the primary years. Children (N=338) in 11 states who were originally tested in 1980 as part of the MAP standardization project were given a…

A longitudinal study was designed to develop and evaluate a screening instrument of developmental delay based on parental assessment of 18-month-old children. The reliability and validity of a parental screening instrument based on the Griffiths Mental Developmental Scale was investigated with a sample of 2,783 Swedish children out of a population…
