Intelligence as measured by the WAIS and a military draft board group test

Intelligence test scores derived from individual administration of the WAIS and group administration of a military draft board screening test were obtained for a sample of 232 young Danish males. The means on both tests show the sample was somewhat above the Danish average. Despite a more than four-year time interval between the two testings, and procedural and content differences between the tests themselves, the correlation between the two test scores was substantial (0.82). Consequently, we conclude that the group administered draft board test measures the same general intelligence as does the individually administered WAIS and is therefore well suited to large-scale epidemiological and demographic studies of intelligence.
