To compare ABA practice efficiency, define the target and mastery rule, then report trials, sessions, teaching minutes, calendar days, errors, prompts, total opportunities, maintenance, generalization, implementation, and client burden. A schedule can reach criterion in fewer sessions while taking more minutes or more days. Percent correct can also hide unequal exposure. Use the outcome tied to the actual family and clinical decision and keep raw counts visible.
Define how to compare ABA practice efficiency
Choose primary units before the comparison: trials to mastery, teaching minutes, sessions, or calendar days. State the starting level, task sets, prompt procedure, consequences, opportunity allocation, mastery rule, and maintenance window.
Use several views
Report correct independent responses per eligible opportunity, errors per target, minutes per correct response, and completed opportunities per planned opportunity. Add client preference, pauses, travel, caregiver time, and disruption when they affect the decision.
Read the evidence precisely
The three-child study found distributed practice more efficient under its verbal-skill procedures. The verbal review summarizes efficiency as a valuable comparative outcome. Neither source makes one efficiency unit sufficient.
Keep interpretation qualified
The BACB outline covers measurement, design, visual analysis, integrity, and data-based decisions. The Ethics Code addresses client involvement, risk, and evaluation. ASHA supports accessible communication throughout each measured condition.
A practical example
One schedule reaches criterion in 6 sessions, 90 minutes, and 21 days; another takes 8 sessions, 72 minutes, and 12 days. Maintenance is 8/10 and 7/10. Each schedule is more efficient on a different unit, so the decision states which unit matters and why.
Questions families can use
Efficient by which unit? Are task sets equal? Did one schedule deliver fewer trials? How many prompts and errors occurred? Did learning maintain? Which time and burden fall on the person and family?
