The school would of course, be a Comprehensive, as opposed to the Army's Grammar Schools and the Navy's Public Schools, as befits the Service's relative position in the grand scheme of things.
All the uniforms would be polyester, with a black tie.
The promotion prospects for the staff are terrible. Some of the staff wear chevrons on their arm, and it's not unusual for them to take until they're 40 to get just two of them. Had they joined a Grammar School, they'd have had those two by the time they were 25. For the ones that wear the stripes on their shoulders, most of them stop at two. Again, the Grammar Schools have their "average Joes" stopping at the equivalent of two AND a little thin one in between.
If the school ran out of a certain colour of exercise book, a UOR would be issued for its replacement at huge cost, and emergency supplies would be procured on Govt credit card. As opposed to simply issuing blue ones instead of the green ones that had been exhausted.
One of the primary metrics of a school is the number of exam passes the pupils obtain. Unfortunately, the school hasn't achieved a single exam pass since World War Two.
The school buses are 40 years old on average, and are incredibly noisy and expensive to maintain. There are two types, the school is the only operator in the world and has been for many years of one of them. The other one is dying a death with other operators, and is likely to be retired by the end of the year. Despite needing a fleet of 40 or more, the RAF has entered into a deal with devil so that they can get a handful of modern 'buses. If not required for school purposes, the buses will be made available to their owner for other purposes. The bus drivers for the new fleet will only be part time, and paid substantially less than drivers of other similar buses.
The school also has a number of vans. These are of two types. One is the older model, they've been thrashed to death, but still do the job. They are literally dying on their feet, there's only a few left of these, but only those models can do certain jobs. The newer ones are still more than 10 years old and have also been thrashed to death. The van drivers have pissing contests on a weekly basis. New larger vans have been ordered, but that was 10 years ago and they still haven't been delivered.
The vans and buses all got moved into the same garage, and it's just been a clusterf*** (see piss up/brewery comment).
Coincidentally, the garage with the vans and buses also houses 6 trucks, which are perfect, but expensive and can only be ordered one at a time.
The Board of Governors are utterly out of their depth when competing with the Grammar Schools and Public Schools for funding. They get outflanked left, right and centre every time. They did manage to get funding for some new logos and a clothing range however. In order to pay for this though, they had to hand over lots of the playing fields and the old van garage to the Grammar Schools, and lose a lot of the sporting equipment (whole fleets) that they used to have on the playing fields.
