| Abstract: | This study investigated the interrater reliability of teachers' and school psychology ex-terns' scoring of protocols for the Developmental Test of Visual-Motor Integration (VMI). Previous studies suggest that the scoring criteria of the VMI are ambiguous, which when coupled with raters' lack of scoring experience, as well as limited knowledge of testing issues, contributes to low rater reliability. The original manual scoring system was used by four trained teachers with no VMI experience and by four experienced raters. A VMI scoring system, revised to eliminate ambiguous scoring criteria, was used by an additional four teachers inexperienced with the VMI and by four experienced raters. High reliability coefficients (>.90) were found for all raters, regardless of the scoring system employed. The influence on interrater reliability of factors such as training, nature of the training setting, characteristics of the raters, and ambiguity of scoring criteria is discussed. |
