Supervision Percentage
The ratio of supervised hours to total fieldwork hours within a supervisory period, expressed as a percentage. The BACB sets minimum supervision percentages that vary by fieldwork type and standards year.
Definition
Your supervision percentage is the proportion of your fieldwork hours that were conducted under direct supervision. It is measured within each supervisory period, which is one calendar month: supervised hours for the month divided by total fieldwork hours for the month. It is not averaged across your entire fieldwork experience, so a strong month cannot make up for a short one.
The minimum supervision percentage depends on your fieldwork type. For supervised fieldwork, you need at least 5% of the month's hours to be supervised. For concentrated fieldwork under pre-2027 standards, the minimum jumps to 10%. The 2027 standards introduce a 7.5% minimum for BCBA concentrated fieldwork, while BCaBA concentrated remains at 10%. These percentages may sound small, but they add up: across 2,000 hours of supervised fieldwork, the 5% minimum represents at least 100 supervised hours.
Because each month stands on its own, the consequences of a short month are immediate and local. In supervised fieldwork, a month that misses the minimum may count fewer of that month's hours toward your total. In concentrated fieldwork, a month that misses the minimum does not count at all. The practical takeaway: check your percentage for the current month while you can still schedule supervision, because once the month ends, it is settled.
Why This Matters
Your supervision percentage is one of the most critical compliance metrics. It is measured within each calendar month, so a month that falls short is settled once the month ends and cannot be repaired later.
Examples
-
Supervised Fieldwork (pre-2027): minimum 5% supervision required
-
Concentrated Fieldwork (pre-2027): minimum 10% supervision required
-
Concentrated Fieldwork (2027 BCBA): minimum 7.5% supervision required
