Hi Pia,
This is on me frankly...I'm the holdup. I am in the process of finalizing the first tranche of communications, etc. Most people who took the course and passed the exam still owe us the referral letter confirming experience requirements. You can find this in the syllabus found here (see Certification Prerequisites section):
TBM Executive Foundation Syllabus (September 2017)
Many have passed the exam so this is should be the only requirement left.
Please respond with any additional questions.
Todd
