To determine if different graded word lists can be used interchangeably for assessment purposes, and to determine if age, grade, or sex affects performance on the different graded word lists, a study examined the Wide Range Achievement Test (WRAT), Levels I and II, the San Diego Quick Assessment, and the Graded Word Reading Test by F.J. Schonell. The three lists were administered to 283 pupils in grades 3 through 12. The word lists were collated in random order and were administered over a two-week period. Results showed that mean scores on the WRAT I, WRAT II, and the Graded Word Reading Test were relatively consistent and all correlation coefficients were significant at the .01 level. However, the mean score on the San Diego Quick Assessment was about one year below the other two. Mean scores for boys and for girls with the San Diego Quick Assessment were 5.05 and 5.79 respectively. No such differences were found for the Graded Word Reading Test or for either form of the WRAT. Conclusions suggest that the San Diego Quick Assessment should be used cautiously when making comparisons within a mixed group. (HOD)
