Certified Scrum Trainer (CST)

Be an integral national and international ambassador of Scrum and the agile movement

About the Trainer Approval Community (TAC)


The TAC (Trainer Approval Community) is a peer-review arm of the Certified Scrum Trainer® application process. TAC members are Scrum Alliance volunteers that have held their CST® certification for at least two (2) years and instruct over 300 CSM® and/or CSPO® students annually. 


The Role of the TAC

The role of the TAC is to uphold and assess the CST certification standards. TAC members offer their time reviewing CST applications, participating in feedback calls, and attending in-person interviews for CST candidates. 


In order to ensure unbiased assessment, we request that aspiring CSTs and prospective candidates do not reach out to TAC members with requests to connect, provide guidance, or offer mentorship. However, other CSTs may have more time available for such outreach and mentoring. Please visit Frequently Asked Questions for more information on connecting with CSTs for co-training and mentorship.
