How to Track BCBA Fieldwork Hours (Supervised vs. Concentrated)

Your fieldwork hours log is not just a record of time — it is a compliance document that will be audited. The BACB reviews submitted hours against documented supervision percentages, observation durations, and activity classifications. If the numbers don’t add up, hours don’t count. If forms are missing, hours don’t count. This guide covers the documentation and tracking mechanics: what to log for every entry, how supervised and concentrated supervised fieldwork differ, which activities qualify, what the monthly verification form requires, and the logging errors that end up costing trainees months of re-accrual.

This is a documentation and credentialing operations guide. It does not constitute supervision or clinical advice.

Supervised Fieldwork vs. Concentrated Supervised Fieldwork

The BACB allows BCBA candidates to accrue hours under one of two pathways — or a combination of both. The fundamental difference is supervision intensity: concentrated supervised fieldwork requires more supervisory contact per hour worked, but because of that higher density, you need fewer total hours to qualify.

Per the BCBA Handbook and the 2027 BCBA Requirements document (effective January 1, 2027), the core numbers are:

	Supervised Fieldwork	Concentrated Supervised Fieldwork
Total hours required	2,000 hours	1,500 hours
Min. supervision (current 2022 standards)	5% of monthly hours	10% of monthly hours
Min. supervision (2027 standards)	5% of monthly hours	7.5% of monthly hours
Monthly minimum	20 hours	20 hours
Monthly maximum (current)	130 hours	130 hours
Monthly maximum (2027)	160 hours	160 hours
Supervision contacts/month (current)	4 per month	6 per month
Supervision contacts/month (2027)	Eliminated — replaced by duration tracking	Eliminated — replaced by duration tracking
Client observation (2027)	60 min/month	90 min/month
Group supervision cap	Max 50% of total supervised hours	Max 50% of total supervised hours

The 1.33x multiplier you may have heard about refers to the temporal value of concentrated fieldwork hours: the BACB states that one hour of concentrated supervised fieldwork carries approximately 1.33 times the value of one hour of supervised fieldwork. This is why you can satisfy the requirement with fewer total hours. You record actual hours worked on all forms — never the multiplied equivalent. The BACB applies the weighting on its end.

Which pathway is right for you depends on your work setting. If your employer can deliver frequent, intensive supervision (smaller caseloads, dedicated supervision structures), concentrated fieldwork lets you finish faster. If you are working in a larger agency where structured supervision is less frequent, supervised fieldwork is the more realistic fit.

Restricted vs. Unrestricted Activities

Not all ABA-adjacent work qualifies as fieldwork, and among qualifying hours, the BACB enforces a composition requirement. Across your total accumulated hours, at least 60% must come from unrestricted activities. No more than 40% may come from restricted activities.

Unrestricted activities are oversight, program development, and indirect service tasks tied to a specific client’s programming. These include:

• Conducting functional assessments and functional analyses
• Designing behavior intervention plans (BIPs) and skill acquisition programs
• Developing and revising data collection systems
• Writing progress summaries and behavior-analytic reports for specific clients
• Providing performance feedback to RBTs and behavior technicians on a client’s program
• Developing discharge and transition plans

Restricted activities are the direct delivery of behavior-analytic procedures to clients — hands-on, face-to-face implementation.

A critical update from the BACB’s August 2025 handbook revision: all fieldwork activities, including unrestricted ones, must be tied to a specific, real client’s programming. Work on hypothetical cases, training exercises not connected to a real client, or general research that isn’t tied to an active client’s treatment does not count.

What definitively does not count as fieldwork hours, per the BACB’s fieldwork guidance:

• Coding and billing
• Studying for the BCBA exam
• CPR and non-behavior-analytic training
• Conference attendance
• Podcasts or case study reviews not tied to an active client
• University coursework or homework

If you are logging time you are unsure about, do not log it until you verify the category with your supervisor. Disputing the classification after you have submitted an M-FVF creates a correction process that requires both parties to initial revisions — avoidable friction.

What Goes in Every Log Entry

Your daily or weekly tracking system is the source document for your Monthly Fieldwork Verification Form. The BACB does not endorse specific software, but whatever system you use — spreadsheet, purpose-built tracker, or dedicated app — each entry must capture enough information to populate the M-FVF and survive an audit.

Minimum fields for each log entry:

1. Date — specific calendar date of the activity
2. Start time and end time — or total duration in hours (not rounded up; log actual minutes)
3. Activity category — restricted or unrestricted
4. Supervisor name — the BACB-certified supervisor who oversees this period
5. Supervision type — individual or group (for hours where supervision was received)
6. Client observation notation — flag entries where your supervisor observed you working directly with a client, and record the duration in minutes (required for 2027 compliance and good practice now)
7. Setting — where the fieldwork occurred

You should maintain a running monthly subtotal that tracks:

• Total fieldwork hours for the month
• Subtotal of hours supervised (individual)
• Subtotal of hours supervised (group)
• Total observation time with clients (in minutes)
• Percentage of hours supervised — calculated as (total supervised hours ÷ total fieldwork hours) × 100
• Running restricted vs. unrestricted split across all months

The supervision percentage calculation is the number that determines whether your month qualifies as supervised or concentrated supervised fieldwork on the M-FVF. If you do not hit the required percentage threshold for the month, you cannot accrue those hours toward the corresponding pathway. Keeping a live running total — not a month-end scramble — is what prevents you from reaching the last week of a month and discovering you are short on supervision contacts or observation time.

The Monthly Fieldwork Verification Form (M-FVF)

At the end of each calendar month in which you accrued hours, you and your supervisor complete and sign the M-FVF. This form is the official document the BACB uses to verify compliance.

What the M-FVF captures:

• Your BACB ID number
• The month being reported
• Total fieldwork hours for the month
• Percentage of hours supervised
• Duration of client observations
• Fieldwork type designation for that month (supervised or concentrated supervised)
• Supervisor attestation confirming all monthly requirements were met

Signing deadline: The M-FVF must be signed by the last day of the calendar month following the month of supervision. If January fieldwork is complete, both parties must sign by February 28. Missing this window creates a correction process. Per the BACB’s documentation FAQ, if it is more than one calendar month after the supervisory period ended, you and your supervisor can still make the relevant changes, but everyone involved must initial the corrections — which is administrative overhead and a red flag if you are audited.

Retention: Both you and your supervisor must retain copies of all M-FVFs, supervision contracts, and supporting documentation for a minimum of seven years.

How Hours Are Verified and Attested

Supervisor attestation is not a rubber stamp. By signing the M-FVF, your supervisor is affirming that:

• They reviewed your hours for the period
• The supervision percentage threshold was met for that month’s fieldwork type
• Client observation requirements were fulfilled
• Activities logged are eligible fieldwork activities
• They were qualified to supervise for the entire duration covered

This means your supervisor needs access to your underlying log, not just the summary numbers on the form. Build the habit of sharing your running log with your supervisor at each supervision contact — not just at month end. This lets your supervisor catch classification errors or calculation problems before they get locked into a signed form.

If your supervisor did not observe you directly with a client during a given month, the observation requirement is unmet. That month still counts toward total hours, but the observation shortfall means it may not satisfy 2027 compliance criteria. Track observation time separately and confirm it with your supervisor before signing.

The Most Common Logging Errors That Get Hours Rejected

The BACB conducts audits on submitted fieldwork. If selected and your documentation is incomplete or inconsistent, those hours are not accepted. Based on BACB guidance across the fieldwork documentation FAQ and the fieldwork checklist, here are the most common problems:

1. Missing M-FVFs. No form, no hours. Candidates who track hours informally but never complete and sign monthly forms have no documentation to submit. The BACB requires the form for every month hours were accrued.

2. Supervision percentage below the threshold. If a month’s hours fall below 5% supervised (supervised pathway) or 10%/7.5% supervised (concentrated pathway), those hours do not count toward that pathway. You cannot retroactively re-categorize the month.

3. Logging non-qualifying activities. Billing, studying, non-client-tied reading, and conference attendance are common entries that do not count. Logging them inflates your hour totals but creates discrepancies if audited.

4. Failing to tie unrestricted activities to a real client. As of the August 2025 handbook update, unrestricted hours must connect to an actual client’s program. General administrative work or hypothetical case planning does not qualify.

5. Recording multiplied hours instead of actual hours. Concentrated fieldwork hours carry a 1.33x multiplier when calculating total progress toward the 1,500-hour target, but you always record the actual hours worked on the M-FVF. Recording inflated figures invalidates the form.

6. Group supervision exceeding 50%. If more than half of your monthly supervised hours come from group supervision, you are out of compliance for that month’s supervision ratio. Track individual and group hours separately every month.

7. Corrupted or unsaved digital files. The BACB explicitly warns that digitally-saved M-FVFs should be opened and reviewed after saving to confirm the file is not corrupted before it is stored long-term. A seven-year-old corrupted PDF is indistinguishable from no record at all.

8. Late or unsigned forms. A form signed after the calendar-month deadline without initials on corrections is non-compliant. If your supervisor becomes unavailable (moves jobs, license lapses, leaves the field), getting corrections signed retroactively can be impossible.

9. Wrong supervisor listed. If supervision was provided by a supervisor not listed on a valid supervision contract, those hours are not creditable. Supervision contracts must be in place before supervision begins.

Keeping a Clean, Audit-Ready Running Total

The goal is to reach your submission date with a complete, internally consistent record — not to reconstruct months of work from memory.

Practical system:

• Log hours on the same day they occur, or within 24 hours. Memory degrades; start and end times become approximations quickly.
• Keep a separate tab or column for your running totals: cumulative unrestricted hours, cumulative restricted hours, cumulative supervised hours (individual), cumulative supervised hours (group), and current percentage breakdowns.
• At each supervision contact, review the prior week’s entries with your supervisor. This is the time to reclassify anything logged in the wrong category — not at month end.
• Complete and sign the M-FVF within the first week of the following month. Do not wait until the last day of the window.
• After signing, save both a PDF and a backup copy. Confirm the file opens correctly before filing it.
• At the start of each new month, verify that your running totals are consistent with your signed M-FVFs. If there are discrepancies, investigate before logging another hour.

The 2027 BCBA Requirements transition also changes what you need to track from January 1, 2027 onward: supervision contact counts are eliminated in favor of cumulative observation duration in minutes. Candidates who are mid-fieldwork as of that date should confirm which standards govern their existing hours with the BACB directly.

What a Fieldwork Tracker Should Do for You

A well-structured tracker automates the calculations that create compliance risk when done by hand: supervision percentages, restricted-vs-unrestricted splits, monthly totals, and the running cumulative count against your 2,000- or 1,500-hour target.

The data you enter in your tracker becomes the source of truth for your M-FVF. A tracker that organizes entries by month, flags when you are approaching the monthly maximum, shows your real-time supervision percentage, and separates individual from group supervision hours removes most of the arithmetic errors from the process.

For more on how BACB supervision requirements interact with the broader credentialing process, see the BCBA Fieldwork and Supervision Guide. If you are approaching certification and want to understand the documentation requirements from the supervisor side, the ABA Supervision Hours Changes for 2027 covers the transition in detail. Candidates working toward BCaBA first should review BCaBA Fieldwork Requirements for the parallel (and in places different) hour and supervision standards. RBTs and behavior technicians whose supervisors are also managing RBT session records will find the documentation parallels useful in RBT Documentation and Session Data.
