The results of a rigorously controlled sampling of mathematics computational skills, as possessed by grades 1 - 12 students attending private and public schools, in a rural semi-urban, contiguous area in Connecticut, are contained in this report. Status study data is presented in a graphic form. The data reported is derived from an item analysis of the mathematical computational sub-section of the Wide Range Achievement Test (WRAT), 1965 revision. No reasons or causes of success or failure are given, but some suggestions from recent research are offered as possible contributing factors. A related document is RC 003 428. (SW)
