THE DEVELOPMENT AND INVESTIGATION OF A GRAPHIC SCORING SYSTEM FOR OBTAINING DERIVED SCORES FOR THE WJ-R AND OTHER TESTS

A recent revision of the Woodcock-Johnson Psychoeducational Battery (W J-R) has been published for use by practitioners in the field of psych oeducational assessment. One criticism of the WJ-R is the lengthy scor ing process that must be used to derive standard scores or percentile ranks for multiple tests and clusters. This scoring process limits the use of select portions of the WJ-R in screening programs, where immed iate derived scores frequently are needed. Thus, the WJ-R was determin ed to be a good instrument for field testing a prototypical graphic sc oring system designed to reduce scoring complexity. Participants were 25 undergraduate students from a large midwestern university who had n o prior experience with the administration and scoring of psychoeducat ional assessment instruments. After a 10-minute standardized training experience, each of the participants scored 20 different hypothetical scores using a graphic scoring system. Analysis of interrater reliabil ity and mean scores suggested that the prototype graphic scoring syste m was a generally efficient, reliable, and accurate method for obtaini ng standard scores for the WJ-R and other tests.
