Because schools can't bullshit maintenance certification curricula and aren't willing to pay qualified faculty.
See also: the alarming number of schools where CS and Data Science courses are still taught by mathematics faulty (because they can't find CS faculty who are willing to work for $70K).
This model of "pay unqualified people to teach a good enough version of the course and hope our consumers don't notice they're being shafted" only works in unregulated fields. Most trades are not unregulated.
My alma mater finally merged CS and SWE, then moved the new CS/SWE degree to Engineering because engineering basically prints money.
Yeah, the crucial thing that most people miss in these discussion is that most schools don’t actually effectively teach what they claim to be teaching. Teachers and students go through the motions, but the students don’t actually end up learning much of anything, and the teachers who nevertheless give them passing grade face no consequence. If a typical high school started offering aircraft maintenance certification, instead of increasing the graduates value on job market, it would simply make the certification to be held as worthless.
That’s far more time than a typical creative writing minor.
I guess in the UK you'd try for an apprenticeship with day release to college for the academic elements (or take a job in a technical field and do an Open University or other distance learning course for the academic side?).
(They specifically asked about a certification not just “some coursework”.)
I think they did answer this: it's because hands-on practical/technical skills are hard to learn and people who can teach them are generally expensive.
so it is a much easier sell a creative writing major in a faculty senate or something similar than Aircraft Maintenance. And when you do get Aircraft Maintenance it usually gets tucked into the engineering or business schools in order to survive.
