What "Exam Dates" Actually Means for the Certified Gemologist Appraiser Credential
Anyone searching for Certified Gemologist Appraiser exam dates is likely expecting a calendar of fixed sittings, such as a spring window, a summer window and a fall window. That is not how the American Gem Society (AGS) structures the initial credential, based on its current public pages. The initial examinations are AGS-controlled and taken online, and the meaningful "dates" for a candidate are the moments you control: when your prerequisites are approved, when you purchase access, when you launch the exam, and when your completion window closes.
That distinction matters for planning. Rather than circling a date on a calendar and working backward, you build your timeline around a sequence of gates. Miss one and the whole schedule shifts. This guide walks through each gate, flags the places where AGS's own pages disagree, and separates what is publicly confirmed from what you will need to verify directly with AGS.
How Initial Exam Access Works
The Certified Gemologist Appraiser (CGA) credential is issued by the American Gem Society. The initial examination is delivered online under AGS control. AGS has not publicly identified an external testing or proctoring vendor, so you should not assume a particular third-party testing center network, appointment portal or walk-in schedule exists.
The sequence of gates
- Hold the foundation credential. Applicants must already be AGS Certified Gemologists.
- Complete approved appraisal education. This is the prerequisite that most often determines your start date, and it is covered in detail below.
- Complete color-vision testing. This is a separate requirement you should schedule early, because it is easy to overlook until the application stage.
- Agree to applicable approved appraisal and report standards.
- Receive prerequisite approval, then pay the exam fee. The initial exam fee is $349, charged after approval. Diamond and Gold member discounts exist, but the amounts are not quoted publicly.
- Launch the exam within your access window and finish before it closes.
One structural detail affects timing: AGS requires employment at an AGS member business, and there is no general non-member exam price. If you are between jobs or changing employers, that can pause your application regardless of how ready you are academically. Our CGA requirements guide covers eligibility in full, and the CGA certification cost breakdown lays out the fee picture.
The Two-Week vs. Three-Week Completion Window Conflict
This is the single most important scheduling fact to get right, and AGS's current pages do not agree with each other:
| AGS Source | Stated Window | What It Describes |
|---|---|---|
| Certified Gemologist Appraiser credential overview page | Three weeks from launch | Access/completion window |
| CGA application terms | Two weeks | Access/completion window |
Both figures describe how long you have to complete the exam after launching it. Neither is a timed-test duration. In other words, neither tells you how many minutes you get on a given section. Treat this as a hard planning constraint: if you launch the exam and the true window is two weeks, assuming three could cost you your access.
Why the window shapes your preparation
The exam includes a practical appraisal-report-writing component, which is not something you can complete in a single evening if you are building a report from scratch. Launching on a Friday and discovering on Sunday that you underestimated the report is exactly the scenario the shorter window punishes. Block out protected time across the full window before you click launch, not after.
Prerequisites That Gate Your Start Date
The prerequisite education is the biggest variable in your timeline. On August 6, 2026, AGS announced updated requirements that replaced the former Appraisals I and II prerequisite with approved external foundational appraisal education. AGS publishes a qualifying-education page listing acceptable routes, and that page explicitly accepts the American Society of Appraisers (ASA) courses GJ201 and GJ202, among other routes.
To be clear about scope: ASA GJ201 and GJ202 are one current AGS-approved education route, not a requirement for every applicant, and they do not make the CGA equivalent to an ASA credential. The CGA remains an AGS credential with its own theory examination and its own practical appraisal-report-writing examination. GJ203 sits outside the minimum route discussed here.
GJ201: Foundation I, Core Principles of Appraising Gems and Jewelry
This course builds the valuation fundamentals that carry through the rest of the program, grounded in the vocabulary and expectations of the Uniform Standards of Professional Appraisal Practice (USPAP).
- Ethics, competency, privacy and the responsibilities of the appraiser
- The three approaches to valuation
- Types of markets and their levels, and definitions of value
- The client / intended user / appraiser relationship
- Basic economic theory, including how macroeconomic and local forces affect jewelry valuation
- Descriptive elements for the types of gems and jewelry appraisers encounter
GJ202: Foundations II, Appraising Gems and Jewelry for Insurance Scheduling
This course applies GJ201 principles to developing and reporting an insurance-scheduling appraisal, with USPAP Standards 7 and 8 forming the basis for development and reporting.
- When and how to apply the primary approaches to valuation
- Recognizing and ranking relevant characteristics of specific property types
- Data research and reconciliation
- Narrative report writing and the required elements of a USPAP-compliant report
- Course credit requires building a new appraisal report, or modifying an existing one, for a single item of jewelry
These two areas are useful as preparation categories, but they are unweighted. They are not an official weighted or exhaustive exam blueprint, and no dated 2026 weighted blueprint for the initial exam has been publicly released. For a closer look at how to use them, see our CGA exam domains guide.
Check the standards edition yourself
Course libraries sometimes carry ancillary reading material from older USPAP editions. Do not assume any particular edition applies to your exam. Verify the current standards independently with AGS and the Appraisal Foundation before you study from them.
Theory and Practical Report Parts: Planning Around Both
The initial credential involves two distinct assessments: a theory examination and a practical appraisal-report-writing examination. AGS has not publicly confirmed the number of questions or tasks, the split between scored and unscored items, the theory response format, the timing of any timed component, or the initial passing threshold. It has also not publicly confirmed whether calculator use, open-book access, adaptive delivery or proctoring rules apply to the initial exam.
What this means for scheduling is simple: do not build a plan around assumptions. If your study plan depends on being able to consult references during the theory portion, or on a particular time limit per question, you are planning around a fact nobody has verified publicly. Ask AGS directly, and prepare as though you will need to recall core concepts without leaning on notes.
Key Takeaway
Treat the report-writing portion as the schedule driver. Theory knowledge can be reviewed in short sessions, but a USPAP-style narrative report needs uninterrupted blocks. Reserve those blocks inside your completion window before you launch, and confirm the applicable window length with AGS first.
If you are wondering how demanding the combination is, our CGA difficulty guide discusses the exam qualitatively without inventing numbers the publisher has not released.
The Recertification Calendar: September 22, 2026 and the 2027 Cohort
Part of the confusion around "exam dates" comes from recertification, which does have a fixed public deadline. It is important not to confuse it with the initial exam.
| Item | Initial Exam | Annual Renewal |
|---|---|---|
| Format | Theory exam plus practical report-writing exam | Open book, untimed |
| Passing threshold | Not publicly verified | 75% |
| Delivery | AGS-controlled online | AGS PRO |
| Timing | Two-week or three-week completion window (sources conflict) | 2026 deadline: September 22, 11:59 p.m. PT (passed) |
| Who it applies to | New applicants | Existing credential holders |
The 2026 renewal deadline of September 22 at 11:59 p.m. Pacific Time has passed. Credentials earned on or after December 1, 2025 do not renew in 2026; their first renewal falls in 2027. Renewal is annual, involves applicable fees, and can include an appraisal-report review when AGS requests one. The fixed continuing-education hour requirement and the annual fee amount have not been publicly verified, so check the current AGS recertification page for specifics.
Building a Calendar Around the Two Prep Domains
Because the initial exam has no fixed public sitting dates, the most useful thing you can do is back-plan from your intended launch day, sequencing the two preparation areas deliberately. The theory-heavy material comes first because everything in the report depends on it.
GJ201-style foundations
- Drill the three approaches to valuation and when each applies
- Memorize market levels, definitions of value and the client / intended user / appraiser relationship
- Review ethics, competency and privacy obligations under USPAP
GJ202-style application
- Practice insurance-scheduling reports under Standards 7 and 8
- Rank property characteristics, then reconcile comparable data
- Draft at least one full narrative report for a single jewelry item
Pre-launch checks
- Confirm the applicable completion window with AGS
- Block protected report-writing time inside that window
- Run mixed practice on our CGA practice test site
This sequencing mirrors the way the two courses build on each other: GJ202 is explicitly the practical application of GJ201 principles. For a deeper study framework, see the CGA study guide, and for fast review of the highest-yield facts, the CGA cheat sheet. Adjust the seven-week shape to your own experience; an appraiser with years of report-writing practice may compress it.
Fees, Expiry Risk, and Scheduling Mistakes to Avoid
The mechanics of purchase create real risk if you schedule carelessly. Several rules are worth stating plainly:
- The $349 fee is charged after prerequisite approval. You cannot buy your way past the education and color-vision requirements.
- The fee is nonrefundable and nontransferable. You cannot hand your access to a colleague or recover the fee if plans change.
- Expired access requires repurchase. If your window closes before you finish, you pay again.
- Member discounts exist but are unquoted. Diamond and Gold members should ask AGS for the actual amount rather than assume.
Common scheduling mistakes
- Launching before confirming the window. The two-week versus three-week conflict is the most avoidable error on this list.
- Starting the exam before finishing the color-vision testing. A missing prerequisite stalls the application, and the delay is entirely preventable.
- Letting employment lapse mid-process. The requirement to work at an AGS member business is part of eligibility, so a job change can interrupt your timeline.
- Treating renewal rules as exam rules. Open-book, untimed, 75% describes annual renewal only.
- Waiting to learn the report format. Draft a practice report well before you launch.

Key Takeaway
Your real "exam date" is the day you launch, and it should be chosen only after prerequisites are approved, the applicable completion window is confirmed with AGS, and you have drafted at least one practice report. Treat anything you cannot verify publicly as a question to put to AGS, not an assumption to build on.
Frequently Asked Questions
AGS's public pages describe an online, AGS-controlled initial exam with a completion window that begins when you launch it, not a published calendar of fixed sittings. Your effective date is set by when your prerequisites are approved and when you launch.
AGS's pages conflict: the credential overview says three weeks, while the application says two. Both describe access or completion windows rather than timed-test durations. Confirm the applicable window with AGS and plan around the shorter figure.
The initial exam fee is $349, charged after your prerequisites are approved. It is nonrefundable and nontransferable, and expired access requires repurchase. Diamond and Gold member discounts exist, but the amounts are not publicly quoted.
The 2026 deadline was September 22 at 11:59 p.m. PT and has passed. Credentials earned on or after December 1, 2025 first renew in 2027. Renewal is an annual, open-book, untimed exam with a 75% pass mark, delivered through AGS PRO.
AGS's qualifying-education page explicitly accepts ASA GJ201 plus GJ202 as one approved route, among others. This does not make the credential equivalent to an ASA credential, and you should check AGS's current list before enrolling in any course.
