Intervention, Management, and Evidence-Based Practice
Domain 6 tests evidence-based practice, goal writing, treatment selection, dosage, progress monitoring, and family-centered management. Questions ask you to justify intervention with client values, clinician expertise, and the best available research rather than habit or one study.
Core rules
- Evidence-based practice integrates research evidence, clinical expertise, and client/caregiver values and preferences. It is not “use only randomized trials.”
- Goals should be functional, measurable, and tied to a baseline. Specify the target behavior, context, accuracy or independence level, and timeframe.
- Consider dosage, intensity, generalization, maintenance, and least restrictive service delivery. For children, coach caregivers and collaborate with teachers; for adults, address participation, AAC, and environmental supports.
- Progress monitoring uses repeated probes and data-based decisions. Change the plan when data show no meaningful response after a reasonable trial.
Worked example
A goal stated as “improve /s/” is not measurable. A better goal is: “During conversational speech with a peer, the client will produce /s/ with 80% accuracy across three consecutive 10-minute language samples, given visual cues fading to no cues.” It names behavior, context, criterion, and support level. The clinician collects baseline, monitors weekly probes, and adjusts cueing if progress stalls.
Traps
Do not write goals with vague verbs such as “understand” or “improve” without observable criteria. Do not treat one favorable study as conclusive. Do not ignore caregiver priorities or cultural context. Do not confuse attendance with treatment intensity. Do not continue a failing plan without data review.
