Each attempt draws a new mix from the question bank. Purchased tests include unlimited retakes for 365 days from purchase and do not automatically renew. Payments are processed securely by Stripe.

Our purpose
Affordable, flexible ABA exam preparation for learners who sometimes need to see a concept from another angle.
About the founder
Function to Fluency was created by L.J. Connors, who holds a Bachelor of Science in Psychology and a Master of Science in Applied Behavior Analysis with a specialization in Autism Spectrum Disorder.
While preparing for the RBT and BCBA certification exams, I noticed that many study resources were either expensive, limited to one learning format, or focused heavily on memorizing definitions. I wanted to create a more affordable option for people who, like me, sometimes need to approach a concept from another angle before it fully makes sense.
Function to Fluency provides several ways to study, including realistic scenario-based questions, detailed answer rationales, domain-focused practice, mock exams, study guides, and SAFMEDS-style flashcards. The goal is to help future RBTs and BCBAs move beyond memorization and practice applying ABA concepts in the way certification questions require.
This resource was created from the perspective of someone who understands how challenging certification preparation can feel. My hope is to make high-quality practice more approachable, flexible, and affordable while helping learners build both confidence and fluency.
