Evidence library
Published exam sources
This library lists the official and licensed references that support facts in our study guides and practice questions. Each entry identifies the publishing organization, jurisdiction, last verification date, and original location so you can check the source directly.
What published means
A source appears here only after it completes our publication workflow. Draft, blocked, stale, withdrawn, and other unpublished records stay private. Publication means the record passed the site's required automated evidence checks; it does not mean the publishing organization endorses this site.
How to use these references
Automated verification can miss changes or make mistakes. Exam rules, fees, eligibility, code editions, and test-provider instructions can change after the displayed verification date. Before registering or relying on a requirement, open the official source and confirm the current details with the responsible agency or provider.

Source registry
Records remain hidden until they complete the publication workflow. You can still browse the available exam-prep catalog or review how publication decisions are made in our methodology.
