ABA Prep: RBT Exam 2026
Written for the 2026 outline
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
ABA Prep is a study app for the RBT certification exam, written to the BACB's Test Content Outline (3rd edition) that took effect on January 1, 2026.
WRITTEN FOR THE CURRENT OUTLINE
The task list changed this year. Six domains, 43 tasks, and Behavior Acquisition dropped from 32% of the exam to 25%. Most study material still follows the retired 2nd-edition list. Every lesson and question here is weighted to the new one.
EVERY ANSWER EXPLAINED
No bare right-or-wrong. Each question tells you why the correct answer is correct and why the tempting one is not - and the explanation always agrees with the answer key.
PRACTICE THE WAY THE EXAM ASKS
The real exam is 85 multiple-choice questions in 90 minutes, and it asks about situations, not definitions. The questions here are short workplace scenarios with four options, drawn across all six domains in the same proportions as the outline.
AN AI TUTOR ON EVERY LESSON
Stuck on a reading or a question? Ask the built-in tutor. It answers from the lesson in front of you - a real-world example, a simpler explanation, or the same idea said a different way.
BUILT AROUND WHAT ACTUALLY LOSES MARKS
The line between what an RBT does and what a BCBA decides. Objective session notes versus subjective ones. Ethics and documentation - the two areas candidates report struggling with most.
WHAT'S INSIDE
- Lessons across all six content domains, mapped to the 43 tasks
- Practice questions weighted to the official outline
- A timed exam simulator built to the real paper's shape
- Review questions attached to every lesson
RESPECTFUL BY DESIGN
Scenarios are written around client dignity, assent and choice. Many people taking this exam are autistic themselves; the language here reflects that.
