Functional Behavior Assessment
A Functional Behavior Assessment is a process for identifying: observable problem behaviors, the contexts where the problem behaviors are most likely to occur, the specific antecedent events within a context which likely predict occurrence of problem behaviors, and the consequences that appear to maintain the problem behavior.
The purpose of a FBA is to provide the basis for construction of a Behavior Intervention Plan or to improve the effectiveness of an existing BIP.
The FBA should result in the following:
Operational definitions of problem behavior(s)
Identification of the contexts where the problem behavior is most likely, and least likely to occur
Identification of the specific antecedent events most likely to predict the identified problem behavior(s)
Identification of the consequences that reinforce the problem behavior
Types of FBA’s
Formal FBA
A Formal FBA requires parental consent and results in a written report based on use of standardized evaluation instruments. Results are used in development or revision of a Behavior Intervention Plan. This includes multiple, extensive observations and a review of existing data.
Informal FBA
An Informal FBA does not require parental consent and does not use standardized evaluation instruments. This will likely include informal observation, and a review of existing data. An informal Behavior Intervention Plan may be implemented by a classroom teacher using point charts or other simple reward systems, or may be developed in collaboration with other support staff. Results will be used for the revision of a BIP.
The Formal FBA is conducted by the School Psychologist, the case manager, or school counselor in collaboration with other pertinent professionals.
