DataStax Academy FAQ
DataStax Academy migrated to a new learning management system (LMS) in July 2020. We are also moving to a new Cassandra Certification process so there are changes to exam bookings, voucher system and issuing of certificates.
Check out the Academy FAQ pages for answers to your questions:
- Haven't heard back about exams or vouchers? [NEW August 7]
- When can I book an exam? [NEW August 10]
- How do I qualify for an exam voucher? [NEW August 10]
- How long are the coupons valid for? [NEW August 10]
- Why can't I see my old exam result or certificate? [UPDATED August 10]
- What happened to my previous exam voucher? [UPDATED August 10]
- Why is my previous course progress not shown on the new Academy?
