Setting mastery criteria is a fundamental part of treatment planning in ABA therapy and goal writing across occupational therapy and speech-language pathology. Without defined criteria, it is impossible to objectively determine when a client has acquired a skill and is ready to move to the next target or be discharged from a goal.
Common mastery criteria formats include: accuracy-based (e.g., 80% correct across 3 consecutive sessions), frequency-based (e.g., independently initiates greeting 5 out of 5 opportunities), duration-based (e.g., maintains attention for 5 minutes in 4 out of 5 trials), and independence-based (e.g., completes the task with no more than 1 verbal prompt). The right format depends on the nature of the skill and the client's baseline.
Mastery criteria also guide decisions about prompt fading. As a client approaches mastery at a given prompt level, the therapist systematically fades the prompt while maintaining accuracy. This ensures skill independence rather than prompt dependence — a key concern in ABA practice.
In practice
BCBAs define mastery criteria for each skill target when designing the treatment program. RBTs collect trial data that is used to calculate accuracy percentages and determine if criteria are met. When mastery is achieved, the BCBA advances the client to the next phase or target.
Key facts
Defines the objective standard for skill acquisition
Common format: 80% correct across 3 consecutive sessions
Must specify: accuracy level, number of sessions/opportunities, and prompt level
Required for IEP goal writing and insurance authorization
Guides prompt fading decisions during skill acquisition
Theralyn tracks goal progress toward mastery criteria across sessions. BCBAs can see at a glance which goals are approaching mastery, which are stalled, and which have been achieved — without manually pulling data from separate session sheets.
Frequently asked questions
What is Mastery Criteria?
Mastery criteria are the pre-defined performance standards a client must meet before a skill or goal is considered learned. In ABA and child therapy, mastery criteria typically specify an accuracy level (e.g., 80% correct) across a defined number of sessions or opportunities, without prompting.
How is Mastery Criteria used in practice?
BCBAs define mastery criteria for each skill target when designing the treatment program. RBTs collect trial data that is used to calculate accuracy percentages and determine if criteria are met. When mastery is achieved, the BCBA advances the client to the next phase or target.
