High-Active Children and Achievement Tests: A two-year follow-up

A two-year follow-up of 52 elementary school children indicated that in fourth grade, as in second grade, language ability, as measured by the WISC-R Vocabulary subtest, was more strongly related to Achievement Test scores among high-actives than among nonhigh-actives. High-active children of low-to-average language ability had significantly lower achievement test scores than nonhigh-actives, with significant decrement in scores in Reading subtest over the two-year period. On the other hand, high-actives of high language ability had scores only slightly lower than nonhigh-actives, with differences that did not reach significance. Discussion centers on implications for further research and for educational interventions for hyperactive children.
