Can I remove a Gold Membership from a kid account and reassign it to someone else? (coach)

Absolutely. Once you've purchased a set of Gold Memberships, they are yours to assign as you choose.
 

Enabling and disabling a student Gold Membership is a one-click function.
From your Coach account Home screen:

  • Click the "My Kids" tab.
  • Click the "Gold Membership" icon (the one with the red/green dots) next to the kid account you'd like to enable or disable the membership for.
  • If you see a gold level icon next to your Kid’s Username, then the Gold Membership is active. If it's a grey level icon, he/she has a basic membership.
