The purpose of this study was to examine utility of a brief experimental analysis (BEA) in determining effective sight word interventions for a student with a history of difficulty with acquiring sight word recognition. Ten interventions were compared in a BEA. Following the BEA, an extended analysis was conducted that compared the two most effective interventions (from the BEA) with a control condition. Even though the BEA found two interventions to be relatively equal, one of the two interventions resulted in acquisition in half the sessions as the other intervention and this was replicated in a second extended analysis. Implications for BEA and recommendations for future research are discussed.
