The CST® certification has always been and remains a rigorous certification. Scrum Alliance® strives to make the CST application process fair and thorough.
Stringent certification requirements required of prospective CSTs to ensure that only those who are qualified to meet this commitment are entrusted to engage in this role on behalf of Scrum Alliance. Applicants wishing to become CSTs are required to meet and maintain the CST Prerequisites and CST Certification Standards for Certified Scrum Trainer professionals.
As an applicant, it is your responsibility to impress upon the Trainer Approval Community (TAC) that you are qualified as a CST and meet the outlined prerequisites and standards. You should not view the application guidelines and associated templates as a certification checklist but rather as a starting place for a great application. Applicants who demonstrate not only that they minimally fulfill the stated guidelines but have gone well beyond them in several respects are likely to find the best success. Applicants who are quick to apply, having only met -- perhaps only in their own view -- the minimum guidelines, are more likely to be rejected and have to reapply.
If you are in doubt about your readiness, please don’t hesitate to reach out to Scrum Alliance by emailing firstname.lastname@example.org
