Certification lifecycle and name history¶
Dated view: 2026-09-30. Of 231 research-inventory entries, 47 have a recorded dated lifecycle event; 184 still need date research. This is a generated repository snapshot. The published page changes when the site is deployed; it is not a live vendor feed.
The event tables show only source-backed dates. A missing row means this inventory has no confirmed dated event for that exam; it does not mean the exam has never changed. The coverage table below shows the research gap by vendor.
For Microsoft Learn study guides, the skills date is transcribed from the exact English 'Skills measured as of' heading. It does not by itself prove that the preceding outline changed on that day. A skills date is different from the date we checked a page. Initial release refers to the tracked exam version, not necessarily the credential's first launch. A beta release is different from general availability. A rename does not by itself create a new exam or replacement. Language-specific dates are shown with their language code; do not apply them to every exam delivery. A catalog check date describes an inventory pass, not a fresh individual lifecycle check.
Conflicting sources and unavailable labs remain visible in study-guide review notes. More research is needed where noted; useful public information can still be published. Community corrections should include a public source and the observed/effective date where known. See how to contribute.
Upcoming dated changes¶
Effective and past dates¶
Coverage and research queue¶
A recorded event does not establish complete lifecycle history. The remaining count identifies exams for which no dated event has been recorded in this inventory. Review the official source before treating any row as current.
Priority gaps¶
These beta or legacy inventory entries have no confirmed dated lifecycle event yet. Their status is a catalog classification, not a release or retirement date.

Evidence notes and next-pass work¶
- AIB-C01: AWS announced beta registration on September 1, 2026 and beta exam delivery beginning September 29 in English and Japanese. The date recorded here is beta exam delivery for AIB-C01; general availability is not inferred. Sources: evidence 1.
- MLA-C01: September 28 retirement applies only to English MLA-C01 delivery. Korean, Japanese and Simplified Chinese remain available until MLA-C02 general availability. The September announcement gives January 14, 2027 for general availability, while the credential page still says TBD. More research needed — next pass; do not apply the English retirement date globally. Sources: evidence 1, evidence 2.
- MLA-C02: AWS announces English-only beta delivery beginning September 29, 2026, with delivery code ME1-C02. This is the MLA-C02 exam-version beta date, not the initial launch of the credential. General availability conflicts: the September announcement gives January 14, 2027, while the credential page says TBD. More research needed — next pass. No exam booking or account availability was tested. Sources: evidence 1, evidence 2.
- C3000-006: Live exam and credential; public exam record last modified October 21, 2026. No prerequisite exam, withdrawal or replacement listed. A client support notice is not an exam lifecycle change. Sources: evidence 1, evidence 2.
- AB-100: Observed October 28: official page displays 2026-11-16 English scope. It is future on the check date; preserve the accepted historical teaching snapshot until a complete objective reconciliation. Earlier dated observations remain historical.
- AB-210: Beta/delayed-results wording remains alongside a sign-in Practice Assessment route on AI Skills Navigator. Actual outline undated, page last updated June 18. Retiring Close Agent objectives and current deployment lifecycle are separate.
- AB-250: October28 group04 complete-guide/objective refresh retains the exact current detailed outline/status bytes. Workflow teaching and scoped product/resource evidence reconciled; source/human/lab limits remain in the group04 report.
- AB-330: Credential heading explicitly beta and body names beta exam AB-330 with delayed-scoring notice. English; 100-minute assessment shown; no current training/practice assessment. Research-only: complete guide/source review pending. Published beta page is present now; earlier anticipated November beta timing must not override current explicit beta status. New credential identity does not establish retirement or automatic replacement of MB-330. Formal prerequisite requirements not established by this bounded identity check. Sources: evidence 1, evidence 2.
- AB-400: Official exam page explicitly makes AB-400 available October16, 2026 and registration available today; English, retirement none. Official PL-400 transition notice corroborates new registration exclusively AB-400. Research-only: complete guide/source review pending. PL-400 existing registrants can still test through October30; new AB-400 identity is not evidence PL-400 was already retired October28. AB-400 blueprint is already registered as ab-400-transition-blueprint, but there is no published AB-400 guide. Formal prerequisite requirements not established by this bounded identity check. Sources: evidence 1, evidence 2.
- AB-410: October 28 group05 complete-guide refresh retains the accepted objective bytes and separately maps current detailed Office PDF tasks. Page update dates do not establish new scope. See group05 report for source gaps, proposed unexecuted workflows and bounded review.
- AB-620: October 28 complete-guide/objective refresh retains the byte-identical current detailed outline. Named workflow teaching and current product/resource observations reconciled; no product lab executed. See group-03 report for bounded source/execution limits. The undated study-page metadata date changed; it does not establish a new skills-effective date.
- AB-650: Beta and English retained; actual outline is undated despite two-version boilerplate. No Practice Assessment listed. November 13 course availability and public lab instructions do not establish delivered classes or included tenant access.
- AB-730: October28 detailed refresh accepts the current English outline; earlier effective-date notices remain historical. No later English revision announced on checked canonical pages.
- AB-731: October 28 complete-guide/objective refresh retains the byte-identical current detailed outline. Named workflow teaching and current product/resource observations reconciled; no product lab executed. See group-03 report for bounded source/execution limits.
- AB-900: October28 detailed refresh accepts the current English outline; earlier effective-date notices remain historical. No later English revision announced on checked canonical pages.
- AI-200: October28 detailed refresh accepts the current English outline; earlier effective-date notices remain historical. Official data-domain weights still disagree; current source gate blocked.
- AI-300: October 28 complete-guide/objective refresh retains the byte-identical current detailed outline. Named workflow teaching and current product/resource observations reconciled; no product lab executed. See group-03 report for bounded source/execution limits. The undated study-page metadata date changed; it does not establish a new skills-effective date.
- AI-500: Current official exam and credential headings omit beta; course/exam pages list AI-500T00. Recorded as active on observed-page evidence, without inventing a GA date. English; no official Practice Assessment listed. Sources: evidence 1, evidence 2.
- AI-901: October 28 complete-guide/objective refresh retains the byte-identical current detailed outline. Named workflow teaching and current product/resource observations reconciled; no product lab executed. See group-03 report for bounded source/execution limits.

- AZ-400: October 28 complete-guide/objective refresh retains the byte-identical current detailed outline. Named workflow teaching and current product/resource observations reconciled; no product lab executed. See group-03 report for bounded source/execution limits.
- AZ-401: Credential and dedicated exam headings explicitly beta; dedicated exam lists English and no retirement date, with score 700 and beta score delay. Study guide last updated October 13, 2026 and lists five DevOps domains. Published guide added October 29, 2026. The credential landing page assessed-domain block repeats unrelated AB-100 content and the exam related-certification summary is generic architect boilerplate; use the AZ-401-specific exam page and study guide for scope. No formal prerequisite credential, duration or question count identified on inspected pages. Microsoft says exam price is based on the country or region where it is proctored; no local numeric amount was recorded. Product/Preview capabilities must be rechecked. Sources: evidence 1, evidence 2, evidence 3.
- AZ-700: October 28 complete-guide/objective refresh retains the byte-identical current detailed outline. Named workflow teaching and current product/resource observations reconciled; no product lab executed. See group-03 report for bounded source/execution limits.
- AZ-800: Microsoft study guide explicitly states the exam was retired September 30, 2026 at 5 PM CST; rechecked October 28. Accepted teaching snapshot remains archived; AZ-802 is the current preparation route. Historical technical gaps remain unresolved.

- MS-102: Retirement November 30 at 11:59 PM CST remains; no direct expert-credential replacement named on checked canonical pages. Credential page lists four prerequisite options while study-guide audience lists three; retain discrepancy. AB-650T00 is replacement training, not proof of replacement expert credential.
- MS-700: Current effective October English outline accepted after complete objective mapping and teaching reconciliation. Historical objective bytes/dated reviews preserved; source and runtime limits remain in the group-02 report.
- MS-721: Live page shows future October 29 English outline. Current April 28 objective/status bytes retained; 173 current and 173 future objectives mapped separately. Future text saved under a separate filename; a reached date does not itself complete acceptance or prove localized delivery.
- PL-300: October28 group04 complete-guide/objective refresh retains the exact current detailed outline/status bytes. Workflow teaching and scoped product/resource evidence reconciled; source/human/lab limits remain in the group04 report.
- PL-400: Registration closed October 16; existing registrations may test through October 30. The PL-400 page now publishes the October 16 four-domain outline, mapped and accepted in this refresh. AB-400 is the new registration route; this does not publish a separate AB-400 guide or prove identical existing-appointment delivery. Courseware retirement remains distinct.
- PL-900: October28 group04 complete-guide/objective refresh retains the exact current detailed outline/status bytes. Workflow teaching and scoped product/resource evidence reconciled; source/human/lab limits remain in the group04 report.

- SC-200: Current effective October English outline accepted after complete objective mapping and teaching reconciliation. Historical objective bytes/dated reviews preserved; source and runtime limits remain in the group-02 report.
- SC-300: Current October 28 wording accepted after complete mapping. Canonical authentication/access weights still conflict:25–30% at a glance and20–25% detailed. Neither is silently selected; source gate remains blocked.
- SC-401: October 28 current published outline accepted. Credential metadata Last Updated October 14 is not a separate effective-scope announcement; earlier date-conflict interpretation corrected. Historical July bytes and dated receipts retained.
- SC-500: October28 group04 complete-guide/objective refresh retains the exact current detailed outline/status bytes. Workflow teaching and scoped product/resource evidence reconciled; source/human/lab limits remain in the group04 report.

- MO-240: Current credential offers Certiport scheduling, lists English and links an MO-240 skills outline; no beta label observed. This is current-label/scheduling evidence, not an established launch date. Research-only: complete guide/source review pending. Current credential displays renewal frequency 60 months. Record as current page observation and VERIFY CURRENT; do not extrapolate to other MOS credentials. Exam code is visible in the credential PDF link label; PDF itself emphasizes role-based performance tasks and does not print MO-240 in its title. Formal prerequisite requirements not established by this bounded identity check. Sources: evidence 1, evidence 2.
- MO-310: October 28 group05 complete-guide refresh retains the accepted objective bytes and separately maps current detailed Office PDF tasks. Page update dates do not establish new scope. See group05 report for source gaps, proposed unexecuted workflows and bounded review.
AB-100's current name and announced update are confirmed by its credential page and study guide. The saved July baseline is discussed in the dated review. The former name is preserved in the public inventory's history; its exact rename date is not inferred from our review date.
Maintain these records in config/certification-seeds.json; see inventory maintenance. Regenerate this page with python scripts/generate_certification_lifecycle.py. Advance lifecycle_as_of deliberately when refreshing the view. The date does not claim every inventory entry was individually rechecked.
