This six‐year review of research on practicum supervision examines articles in terms of findings and the research designs employed. Research is classified according to (a) counselor—supervisor similarity, (b) training methods, and (c) evaluation. Conclusions from the review indicate: (a) the investigators found no support for matching counselors and supervisors according to similar traits; (b) there was some support for modeling, didactic, and experiential methods; (c) there was some support for peer supervision; and (d) an experimental design was used in only 4 of the 19 studies examined.
