Although research has clearly demonstrated the utility of functional assess
ment across a variety of settings and populations, the literature contains
few examples of a comprehensive approach to functional assessment in genera
l education settings that effectively bridges research to the everyday prac
tice of school psychology. Functional assessment has been presented as a th
ree-step process involving informant assessment, direct observations, and e
xperimental analyses. In the present case illustration, teacher interviews,
conditional probability analyses of direct observations, and brief teacher
-implemented functional analyses are demonstrated to help practitioners lea
rn an efficient and effective method for determining the function of proble
m behaviors exhibited in general education classrooms. Future directions an
d implications of functional assessment research and practice in general ed
ucation classrooms are discussed.
