   All three Claude certification banks receive an exam-parity review

   Seventy-three items were added or revised across the three banks: 47 in Architect Foundations (including two new blueprint-correct private-form replacements), 17 in Developer Foundations, and 9 in Architect Professional. The review corrected answer semantics, task mappings, source/version evidence, rationales, counterfactual option notes, and answer-length cues. Final bank sizes are 321 (90 private simulation + 231 drills), 159 (53 + 106), and 189 (63 + 126), with the structural, blueprint, provenance, rationale, cue, bundle-parity, and client-exposure release gate passing with no findings.

   Timed exams gain flag-for-review, a pre-submit review screen, and option strikethrough

   Every timed simulated exam now rehearses the testing-center workflow: flag any question for review, strike out options you have eliminated without changing your answer, and check a review screen listing flagged and unanswered questions — with jump-to links — before you submit. Flags and strikes persist with a paused sitting and never affect grading.

   Applied labs arrive for Architect Foundations

   Ten hands-on, bring-your-own-machine labs join the Architect Foundations study page — build and register an MCP server, run the agentic tool-use loop by hand, author a least-privilege subagent, split a CLAUDE.md into a scoped hierarchy, prompt-caching and eval drills, and more — each with numbered steps, a starter artifact, and a self-check rubric, weighted toward the blueprint's heaviest domains. Architect Foundations was the last track without a labs tab.

   Developer Foundations and Architect Professional banks reach a 3x floor

   169 new scenario-grounded drill items were authored: Developer Foundations grew 78→159 items against its 53-question exam, and Architect Professional grew 101→189 against its 63-question exam, with the depth aimed at the previously thinnest Professional domains — governance 14→27, stakeholder 14→27, enablement 7→12, evaluation 16→30. Every new item carries a difficulty band, a blueprint-task tag, typed distractors mapped to named misconceptions, and per-option notes with counterfactuals, and every grown pool sits inside the measured anti-cueing bounds.

   Per-option study notes reach 100% coverage across all three tracks

   984 notes were authored so every served practice option — across the Architect Foundations drill bank and all four legacy question pools — explains why it tempts and why it fails, without revealing answer cues. The Developer Foundations and Architect Professional banks already carried full per-option coverage; all three tracks now sit behind an automated coverage gate, so an option without an explanation can no longer ship.

   Missed-question re-queue, custom draws, and per-domain score reports

   Practice rounds now remember what you drew and what you missed: a missed-question mode re-serves items until you answer them correctly, fresh draws prefer questions you have never seen (stalest-first when the pool runs short), round sizes are selectable, and every results screen breaks your score down by blueprint domain with a weakest-domain pointer into the study guide.

   Every Architect Foundations item carries a calibrated difficulty band

   The last 90 unclassified study drills were each read and banded (53 straightforward, 34 moderate, 3 hard), completing per-item difficulty plus exam-task assignments across all 319 items. The build now refuses any item without a calibrated band, so an unclassified question can no longer ship.

   Developer Foundations and Architect Professional simulated exams go server-graded

   Both timed forms are now served and graded by the same server-side exam engine as Architect Foundations, so answer keys never reach the browser.

   Spaced-repetition flashcards

   A flashcard deck with spaced-repetition scheduling joins each study surface, built from the existing reference cards and glossary terms.

    Applied labs for Developer Foundations and Architect Professional

    Hands-on lab scenarios join both newer study surfaces alongside the drills.

    Developer Foundations and Architect Professional study surfaces launch

    Both certifications gain dedicated study pages with blueprint-mapped practice drills — 25 Developer Foundations and 38 Architect Professional study items at launch, drawn from dedicated question banks with full blueprint-node coverage and answer-length cues measured out before shipping.

    Architect Foundations bank reaches 319 items across 19 cases

    90 simulation-ready items across six exam scenarios plus 229 study drills across thirteen drill cases.

    Per-option study notes rewritten for shuffled delivery

    262 per-option notes referenced option letters (“B would be correct if…”) that no longer match once options shuffle at draw. Every note now names the approach instead of a letter, so the review sheet cannot mis-cite an option you never saw.

    Answer-cue remediation, measured against official sample items

    Two guessing cues were measured and removed: the correct answer was the uniquely longest option on 96% of drill items (now 11%, versus 17% on Anthropic's own published samples), and one option position held 63% of answer keys (now 25%). Options also shuffle with relabeling on every draw.

    A timed, strict-format simulation drawn from four blueprint-validated form profiles, graded server-side on the official 100–1000 scale.
