Key features of single-case design (SCD) research are presented and reviewed, including AB, withdrawal (ABAB), multiple-baseline, multiple-treatment, and comparative designs. Validity and reliability of these research designs are defined. The relevance and feasibility of using SCD research to build an evidence base of instructional strategies is discussed. Studies within the field of deaf education are examined and analyzed to demonstrate the variety of ways that SCD research can be implemented in the field. Recommendations regarding replication, collaboration, and generalization are noted to encourage researchers to implement SCD studies to advance the field.
