This investigation compared the acceptability of three methods for assessing reading (i.e., norm-referenced assessment, curriculum-based assessment, brief experimental analysis), and explored how a new assessment methodology can gain acceptance as a useful and appropriate approach. Given that brief experimental analysis is a relatively new methodology, it is important to understand not only how it compares to other assessment methods, but also how level of training and use are related to acceptability of assessment methods. A total of 188 members of the National Association of School Psychologists participated, and were randomly assigned to one of the three assessment conditions. Participants read the case description for their assigned condition, and completed the Assessment Rating Profile-Revised (ARP-R; Eckert, Hintze, & Shapiro, 1999). Overall, the results of the study indicated that participating school psychologists rated curriculum-based assessment as more acceptable that either brief experimental analysis or norm-referenced assessment. In particular, participants highly endorsed curriculum-based assessment as helpful in the development of intervention strategies. Although acceptability ratings for brief experimental analysis and norm-referenced were lower and were not significantly different from each other, it should be noted that participants reported significantly less training in brief experimental analysis. For all conditions, reported training and use were significantly correlated. Implications, limitations, and future research directions are discussed. (Contains 3 tables.)
