The purpose of this study was to explore the efficacy and acceptability of problem-solving consultation for homeschooling families with children who exhibited externalizing behavior problems. Three families participated, with multiple siblings participating from each family. Six children were male and 1 child was female. Children's ages ranged from 5 to 9 years old. Single-case experimental multiple baseline designs were used to evaluate the functional relation between implementation of behavior support plans within problem-solving consultation and children's externalizing behaviors. Direct observation data showed decreases in externalizing behaviors after the consultation and intervention process for 2 of the 3 families. The parents of the homeschooling children reported that the behavior support plans and consultation process were acceptable. Implications for future research and practice are presented.
