In FL the districts I have taught in or been a parent in have had two parts...the FABA...the assessment piece. And the BIP...the behavior intervention plan. And it is ongoing...you assess, you plan, you implement, you evaluate implementation and results ....if everyone is happy you keep status quo ...if new things pop up you start over again....but in addition to the intervention usually there is an additional teaching component of some sort of skill that is lacking.

But it isn't a one time event
