The short version
AI Certificates is run by Matthew Hartman. He holds the Claude Certified Architect — Professional credential, scored 965 out of 1000, and writes every question on this site himself. The practice forms, the study guides and the readiness check are all original work built from the published exam blueprints.
How the questions are made
Every item is written from the certification program’s published exam guide — the domain list, the weights and the sub-objectives underneath them. Each question is traced to the specific part of the blueprint it tests, and no question is published until its answer key can be defended from that source alone.
Every answer option carries an explanation, including the wrong ones. That is the part that takes the time and it is the part that matters: professional-tier certification items usually offer two defensible answers and credit one, so knowing why the loser loses is the skill being tested. A bank that only explains the correct answer teaches recognition rather than judgement.
What this site is not
These are not exam dumps. No question here is recalled, leaked or reconstructed from a live exam, and nothing on this site is covered by a candidate agreement. The distinction matters practically as well as ethically: dumped questions go stale silently, carry unverified answer keys, and teach memorisation of strings rather than the discrimination the exams actually test.
The site is also not affiliated with, endorsed by or sponsored by Anthropic. Claude and the Claude certification names are their marks. Everything published here is independent commentary and original preparation material, and the certification program’s own exam guide is always the authority on fees, formats and blueprints.
Corrections
If a question’s key looks wrong, say so — the contact page has the address. Reported key errors get fixed at the source and re-published, and a key change invalidates the attempts scored against it rather than quietly rewriting history.
