- The AAS Case Study Examination is 100 multiple-choice questions with an eight-hour maximum.
- Passing standard is 70%, reported strictly pass/fail - no scaled score is given.
- Roughly half the exam applies supplied case data and calculations; the rest is general appraisal.
- Retakes require a 30-day wait after failure one and a 180-day wait after failure two, capped at three attempts.
Exam Snapshot at a Glance
If you only have five minutes before your review session, this is the page to bookmark. The Assessment Administration Specialist (AAS) designation from the International Association of Assessing Officers (IAAO) centers on the Assessment Administration Case Study Examination - a scenario-driven test, not a generic multiple-choice quiz bank. Every fact below is drawn directly from IAAO's own governing documents, and this cheat sheet is meant to sit alongside your deeper prep, like the AAS Study Guide 2026 and the full breakdown of content areas in the AAS Exam Domains 2026 guide.
Format, Scoring & Retake Rules
The case-study exam is multiple-choice, capped at 100 questions, and candidates are given up to eight hours to complete it. That generous time window exists because a meaningful share of the exam requires you to work through supplied case information - reading exhibits, running calculations, and applying them to specific questions rather than recalling isolated facts.
Scoring is binary: you need 70% correct to pass, and IAAO reports only pass or fail, with no breakdown by score band. For a fuller discussion of what that threshold means in practice, see AAS Passing Score 2026: Exactly What You Need to Pass.
| Attribute | Detail |
|---|---|
| Question count | 100 multiple-choice items |
| Time limit | Eight-hour maximum |
| Passing standard | 70% |
| Score reporting | Pass/fail only |
| Retake wait (after 1st fail) | 30 days |
| Retake wait (after 2nd fail) | 180 days |
| Maximum attempts | Three |
If you fail on your first attempt, IAAO requires a 30-day waiting period before you can retest. A second failure triggers a much longer 180-day wait. After a third failed attempt, the case-study route is closed to you until you complete another accepted project - you cannot simply keep retaking the same exam indefinitely. Notably, this three-attempt ceiling applies only to the case-study exam, not to the separate AAS Master Examination discussed further below. Candidates weighing how strict these rules feel in context should read How Hard Is the AAS Exam? Complete Difficulty Guide 2026.
The Case-Study Content Mix
Unlike a purely theoretical exam, the AAS case-study test is deliberately split roughly down the middle:
Applied Case Data & Calculations (~Half the Exam)
Candidates work from supplied case information - property records, jurisdictional data, or assessment scenarios - and must perform calculations or interpretations based directly on what's given rather than from memorized formulas alone.
- Practice reading dense case exhibits quickly and accurately
- Rehearse the arithmetic you'll need without a reference sheet in hand
- Cross-check your answer against the specific scenario, not general rules of thumb
General Appraisal Knowledge (~Remaining Half)
This portion draws on the broader body of assessment and appraisal knowledge built through IAAO's required coursework rather than case-specific data.
- Reinforce concepts from Courses 101, 102, 400, and 402
- Know applicable appraisal-standards content cold, since it threads through both halves of the exam
- Don't neglect ethics material - Workshop 171 content can surface in general-knowledge questions
Because the syllabus isn't confined to a single textbook, many candidates supplement their core coursework with the optional Workshop 852 AAS Case Study Review, which includes a practice examination. It's a supplement, not a substitute - the required courses still define the real syllabus. For a domain-by-domain walkthrough, revisit the AAS Exam Domains 2026 guide.
Key Takeaway
Split your practice time roughly evenly between calculation-heavy case scenarios and general appraisal review - mirroring the exam's actual composition rather than over-indexing on whichever topic feels more comfortable.
Designation Requirements Checklist
Before you can even sit for the case-study exam, you need to be enrolled and in good standing with IAAO. Enrollment itself depends on meeting the full set of designation prerequisites, which the AAS Requirements 2026 guide covers in depth. The core list:
- High-school diploma or equivalent
- Three years of assessment-field experience
- Credit for IAAO Courses 101, 102, 400, and 402
- An IAAO 300-series course
- Applicable appraisal-standards education (see below)
- Workshop 171 ethics education
None of these are optional shortcuts - enrollment and good standing are prerequisites for taking the case-study exam or submitting an alternative project, so sequencing matters. Build your coursework calendar before you book an exam date; the AAS Exam Dates 2026 guide can help you map testing windows against your remaining coursework.
Appraisal-Standards Education Rule
This is one of the most commonly misunderstood requirements. IAAO splits it by location:
- U.S. candidates: must complete IAAO 151 or a Foundation-approved two-day USPAP course.
- Candidates outside the U.S.: must pass a course covering their own jurisdiction's applicable appraisal standards; if no local standard exists, USPAP becomes the required fallback.
The Three Knowledge-Demonstration Paths
Most candidates default to the case-study exam, but it isn't the only route IAAO recognizes for demonstrating knowledge at the AAS level. Candidates can instead choose:
- The Assessment Administration Case Study Examination (100 questions, eight-hour max, 70% to pass)
- An assessment-administration research project
- An evaluation of a jurisdiction's assessment practices
All three routes still require you to be enrolled and in good standing first. Choosing between the exam and a project route is a strategic decision - some candidates with strong writing and analytical backgrounds prefer a project, while others favor the fixed structure of a timed exam. Whichever you choose, understanding the overall cost implications matters; see the AAS Certification Cost 2026 breakdown before committing to a path.
Proctoring & Test-Day Mechanics
IAAO requires approved proctoring for the case-study exam. CAE and AAS designees are recognized as standard approved proctors by default. If you need a different arrangement - including remote proctoring - it requires separate authorization from IAAO in advance. Don't assume you can arrange your own proctor informally; confirm proctor eligibility well before your scheduled date.
Key Takeaway
Lock in an approved proctor early. If you're hoping to test remotely, request authorization ahead of time rather than assuming it will be automatically granted.
The AAS Master Examination
After you've satisfied every other designation requirement - coursework, experience, ethics, standards education, and the case-study exam or equivalent project - one more hurdle remains: the separate AAS Master Examination. It has its own four-hour time limit and is taken only after everything else is complete. Importantly, the three-attempt cap that governs the case-study exam does not carry over to the master exam, so treat it as a distinct milestone with its own preparation timeline rather than folding it into your case-study review plan.
Recertification Math
Earning the designation isn't the finish line. IAAO requires designees to maintain their credential through ongoing education:
| Recertification Requirement | Amount |
|---|---|
| Total credit hours | 70 hours over five years |
| Appraisal-standards education (U.S. designees) | At least 14 hours, across two different approved releases |
| Ethics education (all designees) | At least 2 hours |
Note that the 14-hour standards requirement applies specifically to U.S. designees and must span two different approved releases - a single long course won't satisfy it if it's only one release. All designees, regardless of location, must log at least two hours of qualifying IAAO ethics education within the five-year cycle. Plan your continuing education calendar the same way you'd plan initial coursework: don't let it pile up in year five.
A Focused Final-Week Review Plan
Generic study techniques matter less here than aligning your remaining time with the exam's actual structure. Here's how to spend your last stretch before test day, built around the exam's known composition rather than a one-size-fits-all template:
Case-Data Drills
- Work through sample scenarios that mimic supplied case information
- Time yourself on calculation-heavy questions to build speed within the eight-hour ceiling
General Appraisal Refresh
- Revisit core content from Courses 101, 102, 400, and 402
- Review your applicable appraisal-standards course material (USPAP or local equivalent)
Full-Length Simulation
- Attempt a full 100-question, timed practice run to build stamina for the eight-hour format
- Use the practice environment at aasexam.com to simulate exam-day pacing
Logistics & Light Review
- Confirm your approved proctor and any remote-proctoring authorization
- Light review only - avoid cramming new material the day before

FAQ
The exam contains 100 multiple-choice questions, with an eight-hour maximum testing time.
You need 70% correct. Results are reported only as pass or fail - there is no numeric score breakdown.
Up to three attempts total. After a first failure you wait 30 days before retesting; after a second failure the wait extends to 180 days. After a third failure, you must complete another accepted project instead of retesting.
No. IAAO also accepts an assessment-administration research project or an evaluation of a jurisdiction's assessment practices as alternatives, provided you're enrolled and in good standing.
No. The three-attempt cap applies specifically to the case-study exam. The separate four-hour Master Examination, taken after all other requirements are met, is not subject to that same limit.
