Enrollment record
Trill music academy enrollment records
An enrollment record was a record of all individuals who enrolled in an educational institution.
In 2371, Benjamin Sisko and Julian Bashir looked up the enrollment records for all Trill music academies in Joran Belar's lifetime an attempt to find more information on him. Instead, they found Yolad Belar, surmising (correctly) that the two were related. (DS9: "Equilibrium")
