I've worked with and for a time within a few different public school systems.
>'I know of multiple school districts that are absolutely plagued by overzealous IT admins, including the director, who lock down teacher and student computers to the point where they're unable to install or use the software they need to learn...'
Locking down desktops is a pretty basic part of successfully managing more than a handful of them, particularly when they're distributed across an entire county. Obviously, there should be a better process for identifying and distributing (in a controlled manner) the software that will benefit these classes, but handing out administrative rights isn't likely a realistic option.
>'Watching educational YouTube videos? That's not even open for discussion.'
The reasons for this should be obvious and you allude to it just below.
As soon as one of the kids catches a glimpse of some cleavage in a recommended video or YT pre-rolls an ad featuring a girl in a bikini the system is looking at a lawsuit, the teacher - unemployment.
>'Most people here wouldn't believe what is going on in many school districts because of overzealous and incompetent IT admins.'
It's a bit much to pile this on the admins. In my experience, those jobs don't pay enough to attract/keep the level of talent they need nor are they given the autonomy to effect change on their own.
I think it's right to call it a structural problem, one with a whole slew of factors. To name a few...
* Vendors abusing E-Rate funds and the like to oversell districts on things they can't afford to maintain or properly utilize.
* The wacky funding schedules of school systems. They tend to get lump sums for 'modernization' and the like, but are restricted from spending it on services with recurring costs or technical hands to run them.
* Individual schools run like fiefdoms which work against centralizing for efficiency. A notable example of this from my own experience is project which could have served an entire county of 100+ schools for well under <$1M being dashed in favor of a grossly inferior, $50k per school solution.
* Super parents pushing their own agendas and self-interest. It's not at all uncommon for someone who coincidentally works for a particular vendor to decide that the vendor they work for is the only viable solution for the district and raise hell until they get their way.
* Inability to retain qualified help. IT people who want to get paid don't work in education. Experienced IT people who want to work in education anyway know to avoid primary education and aim at colleges and the numerous benefits like free-rides for their own children.
