Single-case design (SCD) is an underutilized research methodology in school psychology literature. Despite its relevance to practitioners and applied intervention researchers alike, the majority of intervention research disseminated in school psychology journals tends to involve group designs, such as the randomized controlled trial. Group designs are useful for answering a wide variety of research questions but may not always be relevant to practitioners seeking procedures that work for their students or researchers seeking for the optimal design to answer their research questions. In comparison, the relative dearth of SCD studies in school psychology literature, in conjunction with common values among the field regarding data-based decision making and the scientist-practitioner model to training, raises questions about the cause of this gap. The present study sought to review doctoral training programs in school psychology and evaluate their relative emphasis on SCD in training. Seventy-six American Psychological Association-accredited school psychology programs were reviewed, and results indicated that roughly two thirds of programs do not emphasize SCD during training. Implications regarding school psychology training and research are discussed and recommendations are provided on future directions for school psychology trainers and researchers.
