Automotive trade schools are not to teach process and procedures like "how to remove a tie rod end" or "how to change a head gasket".
Sure there may be a few things like rebuilding various power train components, but it is largely an introduction to troubleshooting and diagnostics (and how things work!). Using scan tools, pressure gauges, wiring diagrams, noise, TSBs, ect ect.
A lot of people bash graduates of trade programs because they expect a higher level of mechanical inclination. Sure they might assemble 1 engine on a stand or use a few hand tools for various other simple tasks, but it is largely going to be day in, day out, understanding waveforms, voltage drop, fuel pressure test, DTCs, clutch/geartrain noise, principles of operation (how gears work or how magnets produce electricity) and learning to write a repair order.
