How Castleport Builds Exam Preparation
Exam prep is a trust business. Here is exactly how we earn it — and how you can check our work.
1. Official-source fact mapping
Before we write a word about an exam, we build a fact map from the exam owner's official materials: test plans, candidate handbooks, policy pages. Each fact — question count, time limit, domains, scoring, retake rules, cost — is recorded with its source and a last-checked date. Facts we have not finished verifying are labeled 'pending verification' on the page, not silently published as certain.
2. Version control for exams
Exams change, and stale prep is worse than no prep. Every exam we cover has version records with effective dates. When an exam changes — like the ASWB examinations on August 3, 2026 — both versions exist in our system, and candidates are aligned to the version they will actually take based on their test date.
3. Original question writing
Every practice question is written for Castleport against the current official blueprint. Questions are never scraped, purchased from recycled banks, or generated by paraphrasing competitors. Each question carries a full rationale: why the correct answer is correct and why each distractor fails. Questions that cannot support a defensible rationale are cut.
4. Named review before approval
Content moves from draft to approved only after review. Our standard requires review by named, credentialed professionals in each field — and until a real reviewer has reviewed a page, that page says so honestly. We never invent reviewer names or credentials; the current reviewer status for every exam is published on our reviewers page.
5. Corrections and re-verification
Published facts are re-checked on a schedule and whenever an exam owner announces a change. Errors reported by readers are investigated, corrected, and logged publicly on our corrections page. A correction is a normal part of publishing, not an embarrassment to hide.
This methodology applies to every page on this site. If you find a page that fails it, report it — that is what the corrections process is for.
