QA / Testing courses
Finding the defect before a customer does, and writing it up clearly enough to be fixed without a follow-up.
4 free qa / testing courses, each ending in a live simulation week and a portfolio of artifacts you keep.

Digital Accessibility Tester
Test websites and services the way disabled people use them: audit against WCAG 2.2 AA, find what automated scanners miss with a keyboard and a screen reader, run fair sessions with disabled users, hold suppliers to their contracts, and write an honest accessibility statement.

QA Analyst
Decide what a sprint's testing time actually covers, review a junior's suite and bug reports for the specific gap rather than a general impression, and weigh what is worth automating against what stays manual.

Senior QA / SDET
Set quality strategy for a whole product: get a flaky suite trusted again, stop a second framework creeping in, move testing down the pyramid, give leadership measures that cannot be gamed, and write a release gate people will not route round.

Software & Web App Testing
Learn to do the QA job: turn acceptance criteria into test cases, work a defect from first symptom to verified fix, log bug reports a developer can act on without asking you anything, and sign a release off honestly.

No. Each course states its own level, and most of this catalogue starts at entry or beginner. A course assumes you can use a computer and read carefully, not that you have done the job before.
A completion certificate with a public verification link, and the artifacts you produced during the simulation week. The artifacts are the part worth showing an interviewer: they are the work, not a score.
