Getting your BCBA® fieldwork right is part math, part logistics, and part habit. If you’ve ever wondered, “How many hours can I count this month?” or “Do I have enough supervision percentage, contacts, and observations?”, this guide turns the rules into simple decision flows, worked examples, and checklists you can paste straight into your week.
We’ll cover the exact percentages for Supervised Fieldwork vs. Concentrated Supervised Fieldwork, the monthly contact and observation requirements, restricted vs. unrestricted activity ratios, acceptable hour ranges per month (including the 2027 updates), and practical templates so you never miss a signature again.
What Counts as Supervision and Why It’s More Than a Quick Check-In
Supervision is scheduled, documented time with a qualified supervisor that includes real-time interaction (not just retrospective notes). It’s where you connect data → decisions: reviewing graphs, discussing function-based rationales, giving/receiving performance feedback, and aligning next steps. Supervisors also conduct client observations of you delivering behavior-analytic services (live or via video, depending on the rules and your supervision contract).
The BACB organizes these requirements by supervisory period (a calendar month), and your logs and forms are signed monthly. Think in monthly sprints.
The Two Fieldwork Pathways and Their Supervision Percentages
You’ll pick one of two fieldwork options:
Supervised Fieldwork
Total hours target: commonly 2,000 hours
Monthly supervision percentage: ≥ 5% of the hours you accrue that month
Concentrated Supervised Fieldwork
Total hours target: commonly 1,500 hours
Monthly supervision percentage: ≥ 10% of the hours you accrue that month
2027 change: under the 2027 requirements, the concentrated option’s supervision percentage shifts to 7.5%. If you plan to apply under the 2027 rules, build your documentation accordingly (details in Sources).
How to use the percentage rule in real life: If you accrue 80 hours this month under the standard pathway, you need ≥ 4 supervised hours (5% of 80). If you accrue 80 hours under the concentrated pathway, you need ≥ 8 supervised hours (10% of 80). Track this weekly so you don’t scramble in the final days.
Monthly Contacts and Observations: A Simple Way to Remember
A contact is any real-time, bidirectional supervision meeting. An observation is your supervisor observing you working with a client (live or video, per policy). In most current scenarios:
Minimum contacts per month: 4
Minimum observations per month: 1 (of you with a client)
Group vs. individual supervision: At least 50% of supervised hours must be individual supervision (not group), especially under the 2027 ruleset.
Pro tip: Combine where sensible. A live observation can double as one of your contacts if it’s interactive and meets the definitions; just ensure you still hit your total supervised hours and contact count for the month.
Hour Ranges per Month and the 2027 Update
Fieldwork only counts within defined monthly hour ranges. Historically, the BACB has set a minimum and maximum per month to keep progress steady and documentation review feasible.
Common current range: 20–130 hours per month
2027 update: the maximum increases to 160 hours per month (minimum remains 20)
Your monthly total is what your supervision percentage (5%/10%, or 7.5% in 2027 concentrated) applies to. If you log outside the valid range, those hours won’t count—so plan your work blocks with the limits in mind.
Restricted vs. Unrestricted Activities
The BACB separates fieldwork activities into two buckets:
Restricted = direct implementation of behavior-analytic services (e.g., running trials, implementing a behavior plan one-to-one).
Unrestricted = analyst activities (assessment participation, data/graphing and visual analysis, intervention design, writing goals and protocols, staff/caregiver training with BST, ethics decision-making, documentation tying data → decisions, coordination with other providers, etc.).
Your cumulative ratio goal:
≥ 60% of total fieldwork hours must be unrestricted (and therefore ≤ 40% restricted).
This ratio is cumulative across your entire fieldwork—not a hard “per month” requirement—but treat it as a monthly habit so you don’t get to month 11 stuck at 80% restricted.
What Actually Counts and What Doesn’t
Counts (examples):
Graphing and interpretation (not just pasting data), with a rationale for next steps
Participating in an FBA/skills assessment; writing function statements
Designing or revising protocols, targets, mastery criteria, and phase-change rules
BST (explain → model → rehearsal → feedback) with caregivers or staff, plus fidelity checks
Ethics reviews and documentation (consent, scope, least restrictive alternatives)
Cross-disciplinary collaboration that changes the plan based on data
Doesn’t count (common pitfalls):
General staff meetings with little or no behavior-analytic content
Passive CE attendance, didactic homework, or non-ABA interventions
“Pasting numbers” without interpretation or decisions
Administrative time unrelated to behavior-analytic service delivery
Use the litmus test: Did I engage in behavior-analytic work that could be evaluated by my supervisor and tied to client outcomes? If yes, you’re on safer ground.
The No-Panic Math: Three Worked Examples
Example 1: Standard Supervised Fieldwork Month
You log: 92 total hours
Supervision required: 5% × 92 = 4.6 → round up to 4.6+ hours (practically, schedule 5 supervised hours)
Contacts: ≥ 4 (real-time)
Observation: ≥ 1 observation of you with a client
Range check: 92 is inside 20–130 → ✅
Ratio check: Keep ≥ 60% unrestricted cumulative
Plan it: two 60-min supervisions + two 90-min supervisions (some individual, some group), one of which is a live observation with immediate feedback.
Example 2: Concentrated Month
You log: 108 total hours
Supervision required: 10% × 108 = 10.8 → schedule 11–12 hours supervised
Contacts: ≥ 4
Observation: ≥ 1
Range check: 108 is inside 20–130 → ✅
Ratio check: Protect unrestricted time; at high supervision intensities, unrestricted work rises naturally—use that to your advantage.
Example 3: Planning for 2027
You log: 140 total hours in a month
Under 2027, the max is 160 (so 140 is acceptable)
If concentrated in 2027, supervision is 7.5% × 140 = 10.5 → plan ~11 hours
Contacts/observations and individual-vs-group supervision rules still apply; log carefully on the 2027 forms.
A Month That Never Slips
Week 1:
Observation early (don’t gamble on week 4).
Supervision #1: update graphs for 2–3 cases, document 1–2 decisions, and assign a micro-project (e.g., rewrite one mastery criterion).
Week 2:
Supervision #2: function statements from ABC notes; design a prompt-fading ladder for one target; ethics vignette (consent update).
Week 3:
Supervision #3: review treatment integrity checks; run a quick BST for a caregiver/staff routine and log fidelity.
Week 4:
Your Compliance Dashboard
Build a simple sheet with conditional formatting:
Daily entries: start/stop, restricted/unrestricted, brief description
Weekly rollups: totals, % unrestricted, supervised hours so far
Monthly checks:
Total hours in range? (20–130 now; 20–160 if using 2027 rules)
Supervision % met? (5%/10% current; 7.5% concentrated in 2027)
≥ 4 contacts?
≥ 1 observation?
≥ 50% of supervised hours individual (especially under 2027)
M-FVF signed by the last day of the following month
Put the dashboard next to your calendar. If any cell turns red by mid-month, schedule an extra contact immediately.
Group vs. Individual Supervision: How to Balance It
Group supervision is efficient and great for generalizing problem-solving skills, but don’t let it crowd out individual hours. A common, safe pattern:
50–70% of supervised time individual
30–50% group, focused on case conceptualization, ethics drills, or design selection
Under coming 2027 standards, at least 50% of supervised time must be individual. Make that your default now; it tends to boost quality anyway.
Avoid These Five Common Pitfalls
Letting supervision percentage slip.
Fix: track weekly. If you’re at 2% by week 2, add an extra contact.
Missing the observation.
Fix: schedule it Week 1. If it falls through, you still have three more weeks.
All restricted, low unrestricted.
Fix: carve out analyst blocks (graphing + interpretation, protocol edits, BST + fidelity). Treat unrestricted as recurring appointments.
Vague notes.
Fix: Always include a sentence that links data → decision → criterion for success (e.g., “Because latency fell from 55s→22s across 4 sessions, we will start 3s time-delay; success = <15s for 3 sessions.”)
Late signatures.
Fix: sign the Monthly Fieldwork Verification Form in your final supervision of the month, or at worst the first week of the following month (before the deadline).

“Because [data pattern], we will [change antecedent/teaching/reinforcement]; success = [specific metric + timeframe].”
School, Clinic, and Telehealth Variations
School: Keep data windows short (5–10 minutes during transitions/independent work), emphasize feasibility (teacher can implement in ≤ 90 seconds), and align with IEP goals/measurement. Observations can occur during class with headphones/video when permitted.
Clinic: Use AM huddles to assign same-day graph updates. Build one BST caregiver session per week—this grows unrestricted hours and boosts generalization evidence.
Telehealth: Batch screen-share graph reviews, protocol edits, and note QA. Plan in-person blocks (biweekly or monthly) for higher-risk observations, integrity checks, or chained skills (e.g., hygiene).
12-Week Compliance Sprint
Weeks 1–2:
Build the dashboard and schedule recurring analyst blocks (unrestricted).
Secure an early observation and complete two contacts.
Weeks 3–4:
Produce two artifacts: graph + rationale and integrity checklist with feedback.
Hit 4 contacts by end of Week 4; sign the M-FVF in your last session of the month.
Weeks 5–6:
Clean up two protocols with measurable mastery and phase-change rules.
Rehearse an ethics vignette and document the decision.
Weeks 7–8:
Run one FCT micro-implementation and measure latency or replacement rate; log unrestricted time.
Keep your supervision % green weekly.
Weeks 9–10:
Deliver a mini case readout in supervision (two graphs, one decision).
Co-train a tech/teacher; gather fidelity data.
Weeks 11–12:
Re-check your cumulative unrestricted ratio (≥ 60%).
Ensure your monthly range and supervision metrics are met; sign the M-FVF on time.
Export artifacts to a portfolio folder (de-identified).
FAQ Quick Hits
Q: Can an observation also count as a contact?
A: Yes—if it’s real-time and interactive—but it doesn’t automatically count toward your total supervised hours unless it meets those criteria. Be explicit in your log.
Q: Is the 60% unrestricted rule monthly?
A: It’s evaluated across your total fieldwork. Still, treat 60% as a monthly habit so you don’t dig a hole.
Q: What if I miss one of the four contacts?
A: You risk the month not counting. Act early—add a contact the moment your dashboard flags a shortfall.
Q: How do 2027 rules affect me now?
A: If you may apply under 2027 (e.g., graduating later), use the 2027 forms alongside current ones and keep to the future hour ranges/percentages so you retain flexibility.
Pulling It Together
If you track weekly, schedule the observation early, and protect time for unrestricted analyst work, the “math” of fieldwork becomes automatic. Keep your hours in range, hit 5% or 10% (or 7.5% for 2027 concentrated) every month, complete ≥ 4 contacts with ≥ 1 observation, sign your forms on time, and maintain ≥ 60% unrestricted cumulatively. Do that for a few steady months, and you’ll stop worrying about eligibility—and start polishing the portfolio that gets you hired.
