Qualifications are a "want" list buddy.

The only qualifications that matter is have Act 120, be 21, have a high school diploma or GED, and don't have a criminal record.

Even the initial hiring may be conditional where the department will pay for you to get your Act 120.

Pay is a correlation to qualifications because it shows what the market values in said qualifications for the position.

You add additional requirements and you're going to have to pay more for it.
