Yo no lo traduciría. Lo dejaría como está, y pondría en parentesis una breve explicación. Aparentemente estos tickets sirven para incentivar su buen comportamiento. Estos vales después van a un sorteo, no son para canjear directamente.

Eagle Tickets

--At various times during the school year, specific behaviors will be selected as target behaviors that are to be encouraged by the faculty/staff (sharing, helping,taking turns, etc.)
--When these behaviors are observed, a student will receive an Eagle Ticket as a token of recognition (Eagle Tickets may also be received for other appropriate behaviors as well).
--At the end of each week, each teacher will collect all of the distributed Eagle Tickets and have a classroom drawing. At least three Eagle Tickets will be randomly selected from each classroom. A student whose ticket is drawn will receive a small reward or a special classroom privilege.
