This paper reports on the administration of the Preschool Attainment Record (PAR), which is used to estimate developmental levels in children from 6 months to 8 years of age. The PAR was given to 17 5-year-old disadvantaged boys and girls of average intelligence. To reduce the tendency of evaluators to inflate scores, the test was administered by both the mother and teacher of each child. Attainment Ages (AA) and Attainment Quotients (AQ) were determined for each child, and these scores were compared for similarity of parent and teacher evaluations. Comparison of AQ scores showed that parents scored boys higher than teachers did, but there were no differences in judgments of girls' developmental levels. It is suggested that the reasons for disagreement between parents and teachers on boys' attainment be pursued. (DR)
