Abstract
Test-retest rs over a period of 1 yr. are presented for scores from group tests of cognitive controls and intellectual abilities for which validity and split-half or short-form reliability estimates were reported earlier by Gardner and Lohrenz (1969). In spite of limitations on the possible reliabilities of certain scores, the reliability estimates obtained for these time-saving group procedures suggest that they can be used effectively for most purposes.Keywords
