Implementing quality control measures in the discipline and professional pr
actice of behavior analysis is a challenging, but nevertheless important, s
tep in the evolution of our field. The Association for Behavior Analysis cu
rrently seeks to ensure quality in behavior analysis by sponsoring an accre
ditation program for graduate academic programs and by promoting certificat
ion of individual practitioners. The accreditation reviews are conducted by
ABA, whereas certification status is awarded by an independent, nonprofit
credentialing entity: the Behavior Analyst Certification Board, Inc. Among
the challenges that ABA faces as it pursues various quality control measure
s, particularly in its educational programs, are (a) how extensively should
academic programs specify the verbal and nonverbal terminal repertoires in
all three branches of behavior analysis (applied, experimental, and concep
tual); (b) how extensively should programs that emphasize applied behavior
analysis integrate science-based criteria for the evaluation of interventio
ns; and (c) how extensively should programs that emphasize service delivery
include training in formal research methodology.
