Compliance Rules Explained
Every rule for this pathway broken down. What it means, how it's calculated, and common mistakes to avoid.
Supervision Percentage
What this means
At least 7.5% of your fieldwork hours in each supervisory period (one calendar month) must be supervised by a qualified BCBA or BCBA-D. This applies to concentrated fieldwork and is measured month by month, not cumulatively. A short month cannot be averaged out by a stronger month later.
How it's calculated
Supervised hours ÷ total hours for the month × 100. Must be ≥ 7.5% in every supervisory period.
Common mistakes
Assuming a light supervision month can be made up later. Because the percentage is checked within each month, a month that falls short can reduce or forfeit the hours from that month, and no later month can repair it.
How ABA FT handles this
ABA Fieldwork Tracker calculates your supervision rate in real time after every entry and warns you immediately if you drop below the 7.5% threshold.
Group Supervision Cap
What this means
No more than 50% of your supervised hours can come from group supervision sessions. Group supervision is defined as supervision conducted with 2 or more trainees present simultaneously.
How it's calculated
Group supervised hours ÷ Total supervised hours × 100. Must be ≤ 50%.
Common mistakes
Over-relying on group supervision because it's easier to schedule. By the time you realize you've exceeded 50%, you need to log many more individual supervision hours to bring the ratio back down.
How ABA FT handles this
The system tracks your group supervision ratio in real time and warns you before you exceed the 50% cap.
Monthly Hour Cap
What this means
You cannot log more than 160 fieldwork hours in a single calendar month. The cap is absolute: hours beyond it in a single month simply do not count.
How it's calculated
Sum of all fieldwork hours in a calendar month. Must be ≤ 160.
Common mistakes
Trying to cram hours at the end of your fieldwork period. If you hit 160 mid-month, no additional hours can be counted until the next month.
How ABA FT handles this
ABA Fieldwork Tracker shows your remaining monthly hours and warns you if adding an entry would push you past the 160-hour cap, without ever blocking the entry.
Monthly Minimum
What this means
You must log at least 20 fieldwork hours per month during any month you are actively accumulating fieldwork. This ensures ongoing, consistent fieldwork engagement.
How it's calculated
Sum of all fieldwork hours in a calendar month. Must be ≥ 20 in active months.
Common mistakes
Taking a month off without formally pausing your fieldwork, or logging only 15-19 hours and assuming it counts.
How ABA FT handles this
The dashboard displays your current monthly total prominently and alerts you if you're approaching the end of the month below 20 hours.
Unrestricted Hour Ratio
What this means
At least 60% of your total fieldwork hours must be in unrestricted activities: the analytic work such as assessment, program design, data analysis, report writing, and training others.
How it's calculated
(Independent unrestricted + Supervised unrestricted) ÷ Total hours × 100. Must be ≥ 60%.
Common mistakes
Spending too much time on restricted delivery work (running sessions, implementing plans) without enough unrestricted analytic work. The 60% threshold is cumulative and hard to recover from late in fieldwork.
How ABA FT handles this
Your unrestricted ratio is tracked in real time on the compliance dashboard, with warnings when you approach the 60% threshold.
Observations
What this means
Your supervisor must conduct direct observations of your fieldwork. Under 2027 standards, observations must total at least 90 cumulative minutes per supervisory period, measured by actual observation start and end times.
How it's calculated
Sum of observation durations within the period. The total must be at least 90 minutes.
Common mistakes
Logging too little observation time across the period. Under 2027, your observations must add up to at least 90 minutes per period, not just one quick check-in.
How ABA FT handles this
When you flag entries as observations, the system records start and end times and sums their durations per period, validating that the total meets the 90-minute minimum.

Frequently Asked Questions
What changed for BCBA concentrated fieldwork under 2027 standards?
Four key changes: supervision minimum decreased from 10% to 7.5%, monthly cap increased from 130 to 160, supervision contacts were eliminated, and observations switched to duration-based with a 90-minute minimum.
Why did the supervision percentage decrease for concentrated fieldwork?
Under 2027 standards, the concentrated supervision minimum dropped from 10% to 7.5%. This slightly reduces the supervision burden while maintaining quality oversight through duration-based observations.
Why is the observation minimum longer for concentrated than supervised?
Concentrated fieldwork requires 90 total observation minutes in each supervisory period (one calendar month), compared with 60 for supervised fieldwork. Like all observation minimums, it is a monthly total, not a per-session requirement.
Is concentrated fieldwork still faster than supervised under 2027 standards?
Yes, you still save 500 total hours (1,500 vs. 2,000). The 2027 changes make concentrated even more attractive: the supervision rate dropped to 7.5% and the monthly cap increased to 160 hours.
