You aren't guaranteed your choice of force. This could be really, really inconvenient. Let's say you live in Southampton, but Hampshire isn't in the scheme this year - you might face the choice of Wiltshire, Kent or Met - and relocating home.
You are posted as a Neighbourhoods Officer for the lifetime of the PN programme (2 years). This might work for some people, but not for others. It does also mean that you may have significant experience gaps when you move forward. Most non-PN officers start in Response or do a rotation that includes Neighbourhoods, but it isn't too common to go directly to Neighbourhoods and stay there as PN officers do. It's unlikely that you will deal with domestic offences or traffic. This might not seem like a big deal now, but these are critical skills / experiences to have as you move on.
PN training is quite intense and on an accelerated timeline. This means that you usually get sent pre-reads to do before you start the course. Essentially, you are not being paid for some of the study, which everyone else is.
In terms of the force this year cohort is ONLY for the MET so people applying is or become aware of in the Assessment Centre if they get to that stage. Furthermore, this scheme is very very competitive at an acceptance rate of 5.5%.
I do know what neighbourhood police officer involves as I have spoken to an PN person still in the force, and he's experiences on top of all my research.
Honestly you get paid from day one of training, but yes you need to do work pre training which I am a final year student anyway, and don't mind doing it.
I will be moving back home to London anyways, so I will not be paying rent other than keeping up with the bills. I think after graduating starting with nearly £37K is not that bad.
I have been in the police cadet for 4 years, and have lots of ideas what they do and have actually assisted them couple times.
It is always soemthing that I've wanted to do since I was kid for multiple reasons (I can write an essay)
