Your supervisee may know how to break a goal into steps and self-manage their progress but, like, we're all human. And modeling prioritizing these crucial steps towards achieving goals is key.
Performance-based training includes demonstrating the skill for them and having them demonstrate it to show mastery.
Competency-based training includes continuing training until the supervisee can demonstrate proficiency in the skill
Behavior goes where reinforcement flows. Reinforce the behavior and achievements to increase these desired behaviors
The goal you set for your supervisees should always set attainable/intentional goals, support your supervisee, and reinforce achievements and desired behavior.
BCBAs should set reasonable, achievable, attainable goals lead to reinforcement, which leads to an increase in the behaviors.
BCBA can use competency-based or performance-based training to assess your supervisee's skillset. The only difference is that competency-based training CONTINUES until proficiency, mastery, expertise is demonstrated.
