One role at a time: we publish a career only when its job data has been checked by hand.
How our research works
Most course reviews repeat the sales page. We start from the job market and work backwards.
01
We read the job market
Every open posting on the public job boards of thousands of companies. We extract the skills, count how often each one is asked for and check the extraction by hand.
02 Coming next
We score every course against it
Each syllabus is mapped to the same skills. The Skills Match Score shows what a course covers and, more importantly, what it leaves out.
03 Coming later
We ask graduates what happened
Verified alumni tell us if they got hired, how long it took and what they'd do differently. Syllabi make promises; outcomes keep them honest.

Independent by design
Nothing here is sponsored. The numbers come from public job postings, and no one pays to change a score, a ranking or what we write.
Read our methodology- Same formula for everything, every role and certification is counted the same way.
- Unflattering results get published. If a certification barely shows up in job ads, we say so.
- Open data. Every report comes with a downloadable dataset.
