Changing Supervisors or Jobs Mid-Fieldwork

TL;DR: Your hours don't disappear when you switch jobs or supervisors. But you need to handle the transition carefully to avoid gaps. This guide covers exactly what to do, step by step, so you don't lose a single documented hour or accidentally create a compliance headache that haunts you later.

Do You Lose Your Hours When You Switch?

The thing that's probably keeping you up at night: if you change jobs, switch supervisors, or relocate to a new state, do you lose all the fieldwork hours you've already logged? The answer is no. Documented hours with signed Monthly Fieldwork Verification Forms (M-FVFs) belong to you, not your employer and not your supervisor. Those hours travel with you wherever you go.

The key word in that sentence is "documented." Hours that haven't been formally verified (meaning your supervisor hasn't signed off on the M-FVF for that month) are in a gray area that you really don't want to be in. This is why getting your forms signed on time, every single month, is so critically important. We'll come back to this repeatedly because it's the number one thing that trips candidates up during transitions.

The real danger with switching jobs or supervisors isn't losing previously accrued hours. It's creating gaps in your monthly supervision compliance. The BACB requires that you maintain specific supervision percentages each month. If you have a month where you're between supervisors and logging fieldwork hours without proper oversight, those hours won't count, and worse, it could raise red flags during an audit. So the goal isn't just to preserve your old hours. It's to make the transition as smooth as possible so you don't lose momentum.

What Happens When You Switch Jobs but Keep Your Supervisor?

This is the simplest transition scenario, and if you can swing it, it's the one you want. You're leaving your current employer but keeping the same supervisor. This happens most often when your supervisor is an independent or consulting BCBA who isn't tied to your specific workplace.

Even though you're keeping the same supervisor, you'll likely need to update your supervision contract. The contract typically references your employment setting, the types of clients you work with, and the specific activities you'll be performing. When your job changes, those details change too. Sit down with your supervisor and review the contract together. Make sure everything reflects your new role accurately.

One thing to watch out for: your activity types might shift when you change jobs. If you were doing mostly direct client work at your previous employer and your new role involves more administrative or training responsibilities, the balance between restricted and unrestricted activities could change significantly. This affects your total hour requirements, so you'll want to understand exactly how your new role maps to BACB activity categories. Check our restricted vs. unrestricted activities guide for a full breakdown.

The good news is that your supervision relationship continues uninterrupted. Your supervisor already knows your strengths, your areas for growth, and your documentation habits. There's no onboarding period, no getting-to-know-you phase. You just update the paperwork and keep going.

What Happens When You Get a New Supervisor at the Same Job?

This one's more common than you might think. Maybe your supervisor is leaving the agency. Maybe the fit just isn't right. Maybe they're taking on too many supervisees and can't give you the attention you need. Whatever the reason, you're staying at your job but getting a new supervisor.

First things first: you absolutely need a new supervision contract with your incoming supervisor before you can start accruing hours under them. No contract means no valid supervision, period. Don't assume that because you're at the same agency everything just rolls over. Each supervisory relationship requires its own formal agreement.

The most important thing you can do in this scenario: get your final M-FVF signed by your outgoing supervisor before they leave. I cannot stress this enough. Once a supervisor has moved on (especially if they've left your agency), tracking them down to sign paperwork becomes exponentially harder. Some supervisors change jobs, change phone numbers, or just become unresponsive. If you have unsigned months when they depart, you could be stuck in a nightmare of unanswered emails trying to get documentation for hours you legitimately worked.

If at all possible, try to create an overlap period where both supervisors are available. Even a week or two of overlap gives you time to handle the paperwork transition, introduce your new supervisor to your caseload, and make sure nothing falls through the cracks. Your outgoing supervisor should also be prepared to remain available for any audit-related questions that might come up after they leave. Have a conversation about this before they go. Get their personal email, their phone number, whatever it takes to ensure you can reach them if the BACB comes asking questions about your hours six months from now.

Your previously documented hours remain completely valid. The BACB doesn't care that a different person supervised your first 500 hours than the person supervising your last 500. They care that each hour was properly supervised and documented at the time it occurred.

What If You Switch Both Your Job and Your Supervisor?

This is the big one. You're changing everything: new employer, new supervisor, possibly a new city. It happens when you relocate, when an agency closes, or when you just need a fresh start. It feels overwhelming, but it's completely manageable if you handle it in the right order.

Your priority list should look like this: first, get every pending M-FVF signed by your current supervisor. Second, make copies of all your documentation: supervision contracts, signed M-FVFs, hour logs, everything. Don't rely on your employer to keep these records for you. If the agency closes or restructures, those files could vanish. Keep your own copies in at least two places (digital and physical is ideal).

Third, secure a new supervision contract before you start logging hours at your new job. This means you need to find and vet a new supervisor as part of your job transition planning, not after you've already started. If you're relocating, begin your supervisor search in your new area well before your move date. Our guide on how to find and choose a BCBA supervisor can help with that process.

During the gap between your old position and your new supervision contract, do not log any fieldwork hours. It's tempting, especially if you're doing clinical work at your new job and it feels like those hours should count. But without an active supervision contract and a qualified supervisor providing oversight, those hours are not valid fieldwork. It's better to have a clean gap of a few weeks than to log hours that will be rejected later.

What Happens If Your Supervisor Loses Certification?

This is the scenario nobody plans for, and it can feel like the rug has been pulled out from under you. Your supervisor's certification lapses, they face disciplinary action, or they relocate and can no longer provide the required in-person observations. Now what?

The good news: hours you accrued while your supervisor was certified and in good standing are still valid. The BACB recognizes that you had no control over your supervisor's certification status, and they won't penalize you for something that wasn't your fault. But this is critical: you must stop accruing new fieldwork hours immediately. The moment you become aware that your supervisor is no longer qualified, any hours logged under their supervision become invalid.

Your first step is to verify the situation on the BACB Certificant Registry. Sometimes rumors circulate before official actions are taken, and you don't want to panic unnecessarily. Check the registry yourself to confirm your supervisor's current certification status. If their certification has indeed lapsed or been revoked, you need to find a new qualified supervisor as fast as possible.

If your supervisor moved away rather than losing certification, you might have options. The BACB allows a portion of supervision to be conducted remotely via synchronous video conferencing. Depending on your situation, your existing supervisor might be able to continue some of your oversight remotely while you find a local supervisor for the in-person observation components. Check our remote and telehealth fieldwork rules guide for the specific requirements and limitations.

In the meantime, get all pending documentation signed. If your supervisor's certification lapsed but they're still reachable, ask them to sign any outstanding M-FVFs for the period when they were certified. Those signatures are still valid because the hours were accrued during a time when they held active certification.

The Transition Checklist

Regardless of which scenario you're dealing with, here's a step-by-step checklist to make sure you don't miss anything during your transition:

1. Get all pending M-FVFs signed immediately. Don't wait until the end of the month. The moment you know a transition is coming, get every outstanding form signed by your current supervisor. This is the single most important step on this list.
2. Make personal copies of all documentation. Supervision contracts, signed M-FVFs, hour logs, observation records. Copy everything. Store digital copies in cloud storage and keep physical copies in a safe place. Your employer's HR department is not a reliable long-term archive for your career documentation.
3. Secure a new supervision contract. Before you log a single hour under a new supervisor, you need a signed supervision contract in place. This contract should detail the supervision schedule, the setting, the types of activities you'll be performing, and both parties' responsibilities.
4. Verify your new supervisor's active certification status. Go to the BACB Certificant Registry and confirm their BCBA certification is active, they've completed the required supervision training, and they have no disciplinary actions. Do this yourself. Don't take anyone's word for it.
5. Update your hour tracking system. Whether you use a spreadsheet, an app, or a paper log, make sure your tracking reflects the new supervisor, the new setting (if applicable), and the date the transition took effect. Clear records prevent audit headaches.
6. Confirm that all supervision requirements carry forward. Review the BACB's supervision requirements with your new supervisor to make sure you're both on the same page about percentages, individual vs. group ratios, observation minimums, and monthly contact requirements. Don't assume your new supervisor knows exactly what your previous arrangement looked like.
7. Do not log hours during any gap in supervision. If there's a period between your old supervision ending and your new contract beginning, those days are a dead zone for fieldwork hours. You can still go to work and do your job, but those hours cannot count toward your BCBA fieldwork requirements. Accept the gap. It's temporary.

What About Taking a Break from Fieldwork?

Life happens. Maybe you need to take parental leave, deal with a health issue, handle a family situation, or just take a mental health break. Can you pause your fieldwork and come back to it later?

Yes, you can. The BACB gives you a five-year window to complete your fieldwork hours from the date you begin accruing. Within that window, you can pause and resume as many times as you need. There's no penalty for taking breaks, and your previously documented hours remain valid throughout the entire five-year period.

There are a few things to keep in mind, though. Your monthly supervision minimums reset when you resume. If you were on a roll meeting all your monthly requirements before the break, you essentially start that monthly compliance clock fresh when you come back. You'll also need a new supervision contract when you resume, since your old one expired when the supervisory relationship ended.

If you're planning a longer break (say, six months or more), it's worth checking whether the BACB has updated any of its fieldwork requirements in the interim. Standards evolve, and what was compliant when you paused might have changed by the time you resume. Staying informed is especially important with the upcoming changes. Our guide on 2027 BACB changes covers what's on the horizon and how it might affect your timeline.

Also, don't underestimate the reentry challenge. After a long break, it takes time to rebuild your clinical rhythm, get comfortable with a new supervisor, and ramp back up to full fieldwork intensity. Expect that adjustment period to feel slow, but you'll get back up to speed faster than you think.
