@trulybadlydeeply I think that's highly specific to your force, as it won't be the same everywhere. I was a Controller as we were called in our Force, so came into the role doing 'dispatching' (we never called it that), we didn't build up to it. It certainly wasn't seen like a degree at all! Police Officers were heavily replaced by civilians well over 20 years ago in that force area.
However as a Controller you ran the incidents and the officers did as directed, we didn't just send people to them - that is dispatching.
999 call handling (and controlling) is a fabulous job, I loved it and all it's vagaries. Call handling alone is a separate role, but Controllers did this as well in their shifts.
The calls range from heart rending to nuisance to repetitive. I've spoken to sobbing rape victims, convinced women to leave the house and get to a safe place while I get someone to deploy the firearms teams to meet them because their husband has a shotgun / knife / machete and is threatening to kill anyone that approaches him. I've taken reports of toddlers that have gone missing from houses, shops and gardens and fortunately all were found safe and well. I've had to deal with perverts wanking whilst pretending they were in danger, and ensuring their phones were cut off in response. Old ladies who can't recognise their husbands and call 999 thinking there is an intruder in the house claiming to know them are some of the saddest. Phonecalls about death are very common - they may be matter of fact from a GP, ambulance control room or carer, or very distressed from the public.
On the other hand, some calls are hilarious as well!
The woman who rang 999 having a very angry rant because she couldn't find B&Q got short shrift from me about misuse of 999. Kids calling 999 is super common and some of them are really cute when they are just babbling away - their parents are always mortified when you speak to them!
RTCs called in by people who haven't the faintest idea where they are are really common, so you soon learn how to map read REALLY well and work out all sorts of rural locations in your county/counties....
However, it is ultimately still a 24hr call centre and there is a high turnover of staff on the call handling only side of it.
I loved it so much that when I joined up as a police officer after doing this job for a few years, I carried on doing this for overtime work throughout the rest of my career. I do miss it.
