The FAFSA is making me crazy again, who knows information about it?

I hate filling out the FAFSA, it is just unpleasant. That being said, it is a necessary evil and I need help!

Does anyone know, when you’re filling out your parents educational levels, how to rank a parent that completed a technical course? My father completed the course to get licensed as an electrician, do I put him his highest level as “high school”, “college or beyond” or “other”?
