I noticed the peer to peer coaching requirement for certification, are there any other requirements, such as completing an exam?

There are only three key requirements to get your certification.
Pass all assessments: You can take the assessments as many times you need to, but you need to pass them all.
Attend at least 80% of Peer Coaching Session: You need to attend 80% of your selected peer coaching session. You only have one peer coaching session per week and you will have 8 different times to choose from.
Sign all related agreements between the institute and student around terms of use, code of ethics and such.
