A certificate is issued when every requirement of the course is met: all lessons completed, all quizzes and exams passed, and all assignments (including the capstone) graded at 50% or more. Track the checklist on Progress or Certificates, then press Claim certificate.
Each certificate has a unique number, a downloadable PDF and a public verification page (QR code) that shows only your name, the course, the issue date and whether it is valid.
