Clients can often choose interspersed task order when the options are safe, accessible, and compatible with the teaching goal. The team can define a task set, offer meaningful choices, record the selected order, and preserve required supports. Choice may change exposure and difficulty, so data should show which tasks were available and completed. The person also needs a clear route to pause, request help, change order, or stop.
Let clients choose interspersed task order
Show the available tasks through the person's usual communication mode. Explain any genuine limits, such as a task that requires equipment or must occur before a transition. Avoid presenting one acceptable option beside choices staff will reject.
Keep the learning question intact
If order is the variable of interest, hold the task set, supports, and observation window steady where practical. If the person changes the task set too, report that as a different choice rather than forcing it into the planned comparison.
Use practice variation as a prompt to measure
The provider survey found broad variation in task-interspersal procedures and heavy reliance on client characteristics and clinical judgment. The object-label study showed that constant practice can perform as well as or better than some mixes. Neither source resolves a client's preferred order.
Protect communication and assent
The Ethics Code addresses understandable communication, client involvement, consent and assent when applicable, and evaluation. ASHA supports continual AAC access. The BACB outline includes client preferences and contextual fit.
A practical example
Dev chooses between new reading first, alternating trials, or a maintained task first. Across six sessions, Dev selects alternating four times and maintained-first twice. The team reports accuracy, time, prompts, and Dev's rating by selected order without calling the choice a reinforcer assessment.
Questions families can use
Are all displayed options acceptable? Can the person change order mid-session? Which tasks remain required and why? Does choice alter exposure? How are pause, help, and stop messages honored?
