Answer:
D. Identify the target behavior
Explanation:
The next step of action to be established by Mr Williams and his IEP team is to recognize the target behavior for advancing a Behavior Support Plan for Joseph. Target behaviors of an individual must be completely and carefully identified in measurable and observable terms.
This will help the IEP team and Mr. Williams to plan decisions and apply counselling that concerns their student's behavior. Identifying the target behavior will also guide in defining the criteria for changing the behavior.
Hence the correct answer is option (D).
