Our high school registrar did the exact same thing.
1). There was a clipboard, in the high school Registrar’s office, for “student requests for final transcripts”, with two questions: where have you committed for Fall____? Are you requesting a student copy? (It was a “confirmation” for the GC’s, and if the choice didn’t coincide with the GC info, then the student was contacted.)
2). The student had to pay $1 at the Cashiers’ office, for a sealed copy, since this transcript would be in addition to the “final” transcript, and a paper copy added extra time to the busy Registrar’s office.
3). The receipt number was then logged into the request form.
4.) The students were told to expect a 1-2 day wait.
5.) The transcript was sealed in an envelope with the stamp marked directly over the seal: “unofficial student copy” in red ink.
Most students did not want to pay the $1 fee, but an even bigger deterrent were the long lines at the Cashier’s office (yearbooks, cap and gown rentals, etc.)
