To play a 17-year-old in senior rugby, the club must follow a two-stage RFU approval process:
1) Secure annual Club Approval via the CB (Constituent Body) on GMS to prove they have suitable safeguarding and risk assessments. (requires annual renewal)
2) submit an Individual Player Approval Form. The 17-year-old cannot play adult rugby until both approvals are confirmed.
