The practice of psychotherapy is a central activity for clinical psych
ologists. Accordingly, psychotherapy training is a fundamental part of
clinical training programs. Yet there is a paucity of empirical infor
mation about the procedures and processes involved in psychotherapy tr
aining, and empirical evidence for the effectiveness of current practi
ces is practically nonexistent. The literature on empirical evaluation
s of therapy training in general, and psychotherapy supervision in par
ticular, is discussed. It is proposed that psychotherapy training can
be improved by applying principles and methods from the area of the co
gnitive sciences concerned with the development and nature of generic
expertise. To illustrate this application, a new instructional format,
''anchored instruction,'' is discussed as a method for providing psyc
hotherapy students with a more thorough comprehension of therapy theor
ies, principles, and procedures than is attainable with current teachi
ng methods.
