This survey of the standardized testing program summarizes the data accumulated from the most recent administration of selected instruments in October 1973. It compares these findings with information from previous years and points to a few trends and possible conclusions. Assessment of mental abilities--1973-74 is presented for grade 1, and assessment of aptitude and achievement--1973-74 is presented for grades 5 and 8. The ACT report includes information on the four measures of academic ability and data about additional student characteristics that appear to have a bearing on success in college. The appendixes contain the testing schedule 1969-74 and item analysis for grades 5 and 8. (RC)
