Research that leads to a practical next step
If you cannot make a data sheet from the goal, it is not a program
I keep running into the same trap in school files.
The BIP is done. The goal is in the IEP. The team feels finished. Then you try to build a data sheet from what they wrote, and you cannot.
That sequence is backward.
A finished document is not a running program. Before the team adds another strategy, it should be able to answer two questions. Can we measure the goal? And can we tell whether staff are actually running the plan?
That second question is the fidelity line. It is a sentence in the BIP that names the check: who looks, at which steps, and how often.
It is not student progress data. Progress data tells you if the student's behavior changed. It does not tell you if anyone used the plan.
It is not a hope. "Staff will implement with fidelity" is not a check. A usable fidelity line sounds like this: During math group, the teacher marks a five-item checklist once a week for whether the prompt, the break, and the reinforcement were delivered as written. The BCBA reviews those checklists every other week.
This is not an argument against writing BIPs. It is an argument for writing them so a classroom can use them.
Most BIPs never say how anyone will know the plan is running
Iovannone and colleagues scored completed FBAs and BIPs from 62 schools in 13 districts. They used the Technical Adequacy Tool for Evaluation on 135 FBAs and 129 BIPs.
The documents were stronger on getting written after the FBA and naming a function. They were weakest where a classroom would actually need them.
The weakest BIP item was a plan for measuring implementation fidelity: how the team will know the plan is being run. 121 of 129 BIPs had no such plan. Almost every file told the team what to do. Almost none included a fidelity line.
The replacement skill was missing in the same way. A fully described way to teach a replacement behavior showed up on only 10 of those 129 plans.
This paper scored documents, not student outcomes. It is one state. It does not prove that a missing fidelity line caused a specific classroom failure. It does show that the parts of the BIP that make a plan usable are the parts teams skip.
The authors' practical move is to score existing FBAs and BIPs, then aim coaching at the lowest items. From this sample, start by writing the fidelity line. Then write the replacement skill so someone can actually teach it.

Train the teacher to coach the para, then fade
If the missing piece is implementation, the next question is who will run the plan when you are not in the room.
Walker and colleagues tested that path. Three special educators each trained a paraprofessional in their classroom to run functional communication training for a student with autism. The training used behavioral skills training: instruction, modeling, rehearsal, and feedback, with a short initial session and follow-up coaching.
Before training, the paras were implementing few of the FCT steps. After the teacher trained them, implementation rose and stayed high. Two of the three still had it a month later. The third classroom's routine changed, so the authors could not collect that follow-up.
The researchers first trained the teachers. Then the teachers trained the paras. Coaching sessions were short. Teachers and paras generally said the training was practical.
This is three classroom teams, FCT, students with autism, and researcher support behind the teacher. It is not a blank check for every plan on a caseload. One teacher was not sure the para would keep the procedures going after the study ended.
The useful model is still there. Do not default to training every para yourself. Teach the special educator to deliver BST, stay for follow-up coaching, then fade. The fidelity line is how you know that coaching is still working after you leave.

Write the fidelity line before you rewrite the intervention
For one current BIP this week, write four lines:
Goal: Can you make a data sheet from the written goal, for one routine, with one observable behavior?
Fidelity line: Does the BIP name who checks whether staff are running the plan, which steps they look at, and how often?
Coach: Who implements, who trains that person with instruction, model, rehearse, and feedback, and can it run without you in the room?
This week: If the fidelity line is blank, write one sentence. Who checks, what they look at, how often. Do not add a new strategy yet.
Using this on one plan is useful. The harder work is making it the default. A file that looks complete is not a program until a team can measure the goal and measure whether staff are running the plan.
That is systems work. Goal quality. A data sheet people will actually complete. A fidelity line in the BIP. A teacher who can coach a para, then a BCBA who can fade.
Build the system behind the plan
That is why I built the School BCBA Transformation Program. School BCBAs apply the work directly to a student, staff member, or system they currently support, including data collection, BIP design, implementation, and staff training.
The next live cohort starts Thursday, October 8, 2026.

Reply if you want: When you pull one BIP this week, what is missing first, the measurable goal, the fidelity line, or the person who will coach it?
