The author explores the validity of sensitivity training for professional social work education with its inherent concern for the relation between experiential and theoretical learning. The various streams in the sensitivity training movement are surveyed and the laboratory concept identified as particularly relevant. A human relations laboratory, offered annually as a supplementary educational opportunity for professional social work students at Adelphi University, is described. A clear definition of goals is stressed, as well as careful planning which includes students. Initial, impressionistic evaluations by students are included. The author concludes that sensitivity training has much to offer for both teaching and practicing social work, and suggests further exploration of the use of the human relations laboratory for social work education.
