Right. There is no certification state-wide that requires an associates degree in any state to fix fucked-up shitters. But alas, in order to be properly trained in most cases, that is how it's done: on the job training with a local chapter of a trade union in conjunction with classroom courses. IE, apprenticeship. For a random trade-based example: Construction Tending & Hazardous Material Abatement For sure. I know an HVAC who was trained by his dad, dropped out in the 9th grade. But he's asking how it's usually done, in most cases, without extraordinary circumstances. Namely, innate abilities and family ties. Most of the time, it's done via classroom education and on-the-job training. I think we're just mis-communicating. Whether or not a physical degree- be it associates or otherwise- is required, depends on circumstance. Ultimately in trades you just need a resume, as there is no degree requirement for any certs (and there often aren't even certs). The point is that you need an education, usually reinforced in a classroom, in order to be learned. Whether or not you get a certificate, a hand shake, or a sexy degree isn't the point I'm trying to make. That's just parsing. Also this. Relax, Brosepharian.
