Questions that come up
About exams and certificates.
01What's the difference between a skill track and a career track?
A skill track covers one subject end to end, such as Core Details, and closes with an exam and a certificate. A career track pulls courses from several subjects in the order one role needs them, such as Studio-Ready Drafter.
02What is the track exam like?
40 questions in 60 minutes: multiple choice, calculations and reading drawings. You pass at 75 percent. The clock keeps running once you start, so set aside a quiet hour.
03What if I don't pass?
You can retake it after 7 days. Your results show which parts are weak, so use the time to redo those chapters.
04What does the certificate count as?
It's proof you passed a Detarva Academy track exam. It isn't a professional competency certificate or a licence to practise. Many people use it in their portfolio when applying, and how much it counts is up to the employer.
05Can I share it online or print it?
Yes. Each certificate has its own number and can be downloaded as a PDF or shared through a link.
