No college degree is officially required. Candidates with aviation related degrees probably have a better chance of making it through. But there are plenty of working controllers who have only a high school diploma or learned the job as enlisted military personnel.

"Have either one year of general work experience or four years of education leading to a bachelor’s degree, or a combination of both"

Since the chances of landing an ATC job are so slim with the degree, what kind of job options does that degree afford you? What kind of job did she end up taking (or doing while waiting on the FAA)?

While waiting for the FAA and since declining the ATC position she's worked at her family's auto repair shop. Pre-FAA she did repair work and for the last few months since returning she's more on the management side. She hasn't yet decided if the family business or something else is the career she wants.
