- The exam has 9 domains; Core Principles of ABA is the largest, spanning 14 subtopics.
- You'll see 125 total questions (100 scored, 25 unscored pretest) - answer all of them.
- Cut score is 72%, and 3 hours cover all 9 domains in one sitting.
- The QASP-S sits between the ABAT and the QBA, so domains lean supervisory, not just direct-care.
How the QASP-S Content Outline Is Built
The QASP-S exam isn't assembled from a generic ABA syllabus. QABA builds its content outline from a Job Task Analysis, refined with subject matter expert (SME) input and validated through a content-validation survey of practitioners already working in supervisory ABA roles. That matters for how you study: every one of the 9 domains reflects tasks that a working QASP-S actually performs - writing behavior reduction plans, supervising ABATs, running preference assessments, and documenting fieldwork hours - not abstract theory disconnected from the job.
If you haven't already reviewed the eligibility path that gets you to test day, it's worth reading the full QASP-S requirements breakdown before diving into domain content, since the 180 hours of approved coursework and 1,000 hours of fieldwork are structured around these same 9 domains.
Domain 1: Autism Spectrum Disorder Basics
What This Domain Covers
This domain establishes the clinical foundation: diagnostic characteristics of autism spectrum disorder, common comorbidities, developmental trajectories, and how autism presents differently across age groups and severity levels.
- Core diagnostic features and how they differ from other developmental conditions
- Sensory processing differences and their behavioral implications
- Communication deficits common across the spectrum
- How ASD characteristics inform treatment planning decisions
Questions here tend to be scenario-based: you're given a client description and asked to identify which characteristic is being described, or how a specific trait should influence programming decisions made later in the exam under skill acquisition or behavior reduction.
Domain 2: Legal, Ethical, and Professional Considerations
What This Domain Covers
This is where the QASP-S role's supervisory identity shows up most clearly. You're tested on the QABA Code of Ethics, confidentiality requirements, scope of practice boundaries between ABAT, QASP-S, and QBA, and professional conduct expectations.
- Informed consent and client rights
- Mandated reporting obligations
- Conflicts of interest and dual relationships
- Documentation and record-keeping standards
- Supervisory responsibility when delegating to ABATs
Because you agree to the QABA Code of Ethics as part of certification, expect questions that ask you to apply the code to a specific workplace situation rather than just recall its provisions verbatim.
Key Takeaway
Ethics questions on the QASP-S exam almost always involve a supervisory decision - knowing the code isn't enough; you need to know how it applies when you're the one signing off on an ABAT's work.
Domain 3: Core Principles of ABA
What This Domain Covers
Core Principles of ABA is the largest single domain on the exam, spanning 14 distinct subtopics. This breadth means it deserves a disproportionate share of your study time.
- The four-term contingency and how it differs from the three-term contingency
- Motivating operations (establishing and abolishing operations)
- Schedules of reinforcement - fixed/variable ratio and interval schedules
- Verbal operants (mand, tact, echoic, intraverbal)
- The seven dimensions of applied behavior analysis
- Positive and negative reinforcement versus punishment
- Stimulus control and generalization
Because this domain covers so much ground, it's the section most likely to make or break your score. A dedicated review of core terminology - ideally condensed into a single reference - pays off here; the QASP-S cheat sheet is built specifically to consolidate these 14 subtopics into a fast final review.
Domain 4: Antecedent Interventions
What This Domain Covers
This domain tests your ability to modify the environment before a behavior occurs, rather than reacting after the fact.
- Environmental arrangement and setting event modification
- Visual supports, schedules, and priming strategies
- Choice-making and embedding preferred activities
- High-probability request sequences
Expect application questions where you're given a challenging behavior scenario and asked to select the antecedent strategy most likely to prevent it - distinguishing this from a consequence-based strategy tested later under Domain 6.
Domain 5: Skill Acquisition Programming
What This Domain Covers
This domain covers how a QASP-S designs, monitors, and adjusts programs aimed at building new skills.
- Discrete trial training (DTT) versus naturalistic teaching procedures
- Prompting hierarchies and prompt fading
- Task analysis and chaining (forward, backward, total task)
- Shaping and successive approximations
- Generalization and maintenance planning
This domain overlaps conceptually with Core Principles of ABA but focuses on applied program design rather than terminology - expect longer scenario stems describing a learner's current skill level and asking which teaching procedure to implement next.
Domain 6: Behavior Reduction Interventions
What This Domain Covers
This domain tests function-based intervention design for reducing interfering behaviors.
- Differential reinforcement procedures (DRA, DRO, DRI, DRL)
- Extinction and its predictable side effects
- Function-based treatment matched to FBA/FA results
- Crisis and safety plan components
Because behavior reduction decisions have real safety implications, this domain frequently pairs with Domain 8 (Assessment) - a question may give you assessment data and ask which reduction procedure is indicated by the identified function.
Domain 7: Data Collection and Analysis
What This Domain Covers
Since a QASP-S reviews data collected by ABATs and makes programming decisions from it, this domain tests interpretation as much as collection method.
- Continuous measurement (frequency, duration, latency) versus discontinuous (interval recording, time sampling)
- Graphing conventions and reading trend lines
- Interobserver agreement (IOA)
- Using data trends to trigger program changes
Graph-reading items are common: you'll be shown a simple line graph and asked to identify a trend, a level change, or whether a program is meeting mastery criteria.
Domain 8: Assessment
What This Domain Covers
This domain covers the assessment tools a QASP-S is expected to administer or oversee, distinct from the more advanced assessments reserved for the QBA tier.
- Preference assessments (single-stimulus, paired-stimulus, multiple-stimulus)
- Functional behavior assessment (FBA) components
- Indirect assessment methods (interviews, rating scales)
- Skill assessment tools used to build acquisition programs
Since QASP-S is the mid-tier role between the ABAT and the QBA, assessment questions typically test your ability to conduct and interpret assessments, not design novel functional analyses from scratch - that distinction is worth understanding conceptually as you review this domain.
Domain 9: Training and Supervision
What This Domain Covers
This is the domain most unique to the QASP-S credential, reflecting its role as a supervisor of ABATs and direct-care staff.
- Behavior skills training (BST) components: instruction, modeling, rehearsal, feedback
- Performance monitoring and fidelity checks
- Ongoing supervision requirements - including the 5% monthly direct-service-time contact rule
- Delivering corrective feedback and documenting supervision
QABA's ongoing supervision standard - meeting a supervisee for at least 5% of their monthly direct service time, with at least one contact conducted in person or live via video for a minimum of one hour - is tested here as applied math-and-policy questions: you may be given a supervisee's monthly hours and asked to calculate the minimum required supervision contact.
Weighting the Domains in Your Study Plan
QABA does not publish exact percentage weightings per domain, but the subtopic count gives a useful proxy: Core Principles of ABA's 14 subtopics make it the clear priority, followed by the applied domains (Skill Acquisition, Behavior Reduction, Data Collection) that draw on those principles. Domain 9 (Training and Supervision) deserves extra attention specifically because it's unique to this credential - it won't be a strong point if your background is mostly direct-care ABAT work.
| Domain | Primary Focus | Study Priority Signal |
|---|---|---|
| Domain 1: ASD Basics | Diagnostic and developmental foundation | Baseline knowledge |
| Domain 2: Legal/Ethical | QABA Code of Ethics, scope of practice | High - applied scenarios |
| Domain 3: Core Principles of ABA | 14 subtopics: contingencies, reinforcement, verbal operants | Highest - largest domain |
| Domain 4: Antecedent Interventions | Prevention-focused strategies | Moderate |
| Domain 5: Skill Acquisition | DTT, prompting, chaining, shaping | High - applied design |
| Domain 6: Behavior Reduction | Differential reinforcement, extinction | High - function-based logic |
| Domain 7: Data Collection/Analysis | Measurement systems, graph interpretation | Moderate to high |
| Domain 8: Assessment | Preference assessments, FBA components | Moderate |
| Domain 9: Training/Supervision | BST, supervision ratios, feedback delivery | High - unique to QASP-S role |
Foundation Domains
- Review Domain 1 (ASD Basics) and Domain 2 (Legal/Ethical) together since both establish baseline knowledge
- Read through the QABA Code of Ethics in full at least once
Core Principles Deep Dive
- Dedicate two full weeks to Domain 3's 14 subtopics - this is the highest-yield domain
- Drill verbal operants and reinforcement schedules until automatic
Applied Domains
- Move through Domains 4, 5, and 6 together since they build on Domain 3 concepts
- Practice scenario questions that link antecedent strategy to function
Data, Assessment, and Supervision
- Cover Domains 7, 8, and 9, with extra time on the 5% monthly supervision calculation
- Take a full-length timed practice exam under 3-hour conditions

Question Format and Exam Mechanics
The QASP-S exam consists of 125 total questions delivered in a 3-hour window: 100 are live scored items and 25 are unscored pretest items used by QABA to validate future exam content. You won't know which is which, so answer all 125 as if every question counts. The exam is remotely proctored by Premier Proctoring, and certification costs 300 USD (excluding retake fees), with discounted pricing available for residents of developing countries.
The passing point is a 72% cut score. Because that threshold applies across all 9 domains combined rather than domain-by-domain, a weak Domain 9 score can potentially be offset by strong performance in Domain 3 - but you shouldn't rely on that. For a deeper look at how the cut score is calculated and what it means in practice, read the dedicated QASP-S passing score breakdown.
If you're still deciding whether this exam format suits your preparation style, the QASP-S difficulty guide walks through what makes the 9-domain structure challenging compared to other ABA-adjacent credentials, and the QASP-S pass rate article discusses what's publicly known about outcomes.
Who Actually Tests on These 9 Domains
The QASP-S sits as the mid-tier credential in QABA's three-tier paradigm, positioned between the ABAT technician and the QBA behavior analyst. That structure explains why Domains 2 and 9 lean so heavily toward supervisory content - employers hiring for QASP-S roles expect someone who can both apply ABA principles directly and oversee ABATs applying them. Autism service agencies, ABA clinics, and school-based programs typically hire QASP-S holders specifically to fill this supervisory gap. You can explore what these roles look like in practice on the QASP-S jobs page, and get a fuller picture of the credential's history and purpose on the QASP-S certification overview.
Before committing to the coursework and fieldwork investment, many candidates also want to know whether the credential pays off financially - that's covered in detail in the QASP-S ROI analysis and the QASP-S salary guide, alongside the full QASP-S certification cost breakdown.
Once you've mapped your study plan against these 9 domains, running full-length timed practice sessions on our QASP-S practice test platform is the fastest way to find out which domains still need work. Because the real exam mixes all 9 domains together rather than grouping them, practicing with mixed-domain sets on the practice site better simulates what test day actually feels like than studying domains in isolation.
Frequently Asked Questions
QABA doesn't publish exact per-domain percentages, but Core Principles of ABA is the largest domain by subtopic count, spanning 14 areas from the four-term contingency through the seven dimensions of applied behavior analysis, making it the highest-priority domain for study time.
QABA has not released official weighting percentages for each domain. The content outline is derived from a Job Task Analysis and content-validation survey, and subtopic breadth (like Domain 3's 14 areas) is the best available signal for relative emphasis.
No. Of the 125 total questions, only the 100 live scored items count toward your result. The 25 unscored pretest items are unmarked and used for future exam validation, but since they're not identified, you should answer every question as if it counts.
Yes. Domain 9 is tested on every QASP-S exam regardless of your current job title, since the credential itself is designed around supervisory competencies, including the 5% monthly supervision contact standard you'll need to apply once certified.
Your approved coursework and supervised fieldwork are structured to build competency across all 9 domains, including the required minimums of 20 hours in ethics and 15 hours in autism core knowledge. Fieldwork hours cannot be accrued before the first course in your QASP-S coursework sequence, so domain knowledge is meant to precede applied hours.
