Replacement skill

The skill must work for the person

A useful replacement gives the person a practical route to the same need or another outcome they value. Examples can include asking for help, ending or changing an activity, declining, waiting with chosen support, moving to a quieter place, repairing a misunderstanding, using a safety routine, or completing a daily task with accessible tools.

The phrase can mislead when it centers adult convenience. Eye contact, quiet hands, speech, or blanket compliance are poor defaults. A goal needs a person-selected or meaningfully agreed purpose, an attainable response form, and an environment prepared to honor the response. An existing gesture, movement, or AAC message may already communicate the need; the first change may belong with partners.

Full-text access requires a license. This article uses the public scope and presents its selection framework as editorial guidance.

Replacement skill and functional communication differ

Replacement skill is a broad planning term. A functionally equivalent alternative response produces the same class of outcome associated with the response selected for change. Functional communication training, or FCT, is a specific function-based approach that strengthens a recognizable communication response that accesses that outcome.

In the original four-child study, Carr and Durand assessed conditions associated with the selected behavior and taught spoken requests for attention or assistance. The new responses increased and the selected behaviors decreased in those cases. This small 1985 study neither establishes a universal protocol nor supports a speech-only requirement.

A later review by Tiger, Hanley, and Bruzek examined 91 FCT articles involving 204 participants published through 2006. It emphasized identifying the relevant outcome, selecting a recognizable response that can be learned efficiently, teaching it, and extending it across settings and partners. The review reflects the included literature and its era; individual planning still requires current assessment, communication expertise, safeguards, and consent.

Select the skill with six practical tests

Before teaching, ask:

1. Need: What outcome, access, escape, assistance, regulation, safety, connection, or information does the person seek?
2. Existing repertoire: How does the person already communicate or solve this problem through speech, AAC, sign, gesture, movement, writing, or action?
3. Effort and speed: Can the person use the response early and reliably under the relevant conditions?
4. Recognition: Will familiar and unfamiliar partners understand it, and is a backup available?
5. Consequence: Can partners deliver the relevant outcome quickly and consistently enough for learning?
6. Fit: Does the skill preserve dignity, health, autonomy, culture, access, relationships, and daily feasibility?

A 2023 practitioner guide organizes FCT response selection around effectiveness, response effort, social recognition, and the likely persistence of the new communication. It is a practitioner proposal informed by prior research, rather than proof that one response form fits every person.

Sometimes the safest solution reduces the need for a replacement response. Examples include treating pain, improving task clarity, lowering noise, restoring AAC access, adjusting pace, offering genuine choice, or removing an avoidable hazard. Teaching a person to request relief does not excuse a preventable environment or a partner who ignores the request.

Build partner and environment responsibilities into the plan

A complete plan defines more than the learner response. It states:

• the situations and opportunities in which the skill can help
• the exact accessible response forms that count
• the support, wait time, and prompting boundaries
• what each partner does after the response
• the ordinary tools and accommodations that stay available
• safety, health, and escalation limits
• how the skill transfers across people and settings
• how the person can withdraw assent or ask to change the plan

The BACB BCBA Test Content Outline, 6th edition covers functional assessment, client-informed goals, function-based interventions, skill acquisition, generalization, maintenance, treatment integrity, and data-based modification. It is examination content, not authority to implement a particular plan.

For BCBA and BCaBA certificants and people who have completed an application for either credential, the current BACB Ethics Code addresses competence, client and stakeholder involvement, informed consent and assent when applicable, client preferences, assessment-based intervention, risk, restrictive procedures, and continual evaluation. BACB has no separate jurisdiction over organizations or corporations; the practice needs its own accountable policies.

Keep AAC and basic access available

ASHA's AAC practice portal says AAC users should always have access to their tools or devices. A plan should accept effective speech, AAC, sign, gesture, and other reliable forms that fit the person. Communication access must remain available before, during, and after teaching.

Adequate food and water, bathroom access, movement and mobility, relationships, prescribed health care, pain care, and safety remain available regardless of performance. A person should not have to earn the right to communicate, escape harm, report pain, or decline an optional activity.

Measure the whole arrangement

Report the replacement skill as occurrences divided by defined opportunities or as a rate in a stated observation period. Also measure whether the communication system and other supports were available, whether partners responded as planned, and whether the relevant outcome occurred. Keep prompted and independent responses separate.

Track the response selected for change, distress, safety, generalization, burden, and the person's view of whether the new arrangement helps. A higher skill count alone cannot establish benefit if partners delay help, opportunities are contrived excessively, or the person dislikes the goal. When conditions differ, keep denominators separate.

A fictional planning example

Jamal is a fictional nine-year-old who uses gestures and AAC. At a crowded bus stop, he sometimes pushes an adult away. Assessment suggests several possibilities, including noise, closeness, pain, and an attempt to create distance. Jamal selects an AAC message meaning “move back or leave,” and the team also plans a quieter waiting location. The message produces space or an immediate move to the quieter location.

Across 8 predefined crowded-arrival opportunities, AAC is available in 6 of 8 (75%). Jamal uses the message in 5 of those 6 (83.3%). Partners honor it within ten seconds in 4 of 5 messages (80%). In the two arrivals without AAC, Jamal uses his existing push-away gesture once. These figures reveal an adult access failure and one delayed partner response. They do not show that the new message caused any change.

The team restores AAC access, accepts both recognizable forms, examines the delayed response, and asks Jamal whether the quieter waiting plan feels better. It avoids treating every crowded arrival as a teaching opportunity when environmental prevention is available.
