Just talk turf with them. You should be able to better gauge it by talking with them instead of testing them. Ask them about turf varieties (throw some Bermuda, Zoysia, Kikuyu, etc at them although they obviously don't apply in Rockford).
Ask about chemicals used, throw ai names at them not the Trade name (ie, trinexipac-ethyl instead of primo)
This should help you get an idea of where they are at turf education wise. It won't however tell you about their work ethic per say, although if they claim to have to turf school and have little to no turf knowledge they may have skated through and not put in the study time.
Maybe reach out to a few turf professors for some turf 101 quizzes. I'd start with Branham (Illinois), Christians (ISU), and Rogers(MSU).
Good luck filling the position as there seems to be a shortage of assistants right now.
