You definitely need to know who the HCPC is…
The College of Paramedics might be useful too, free CPD (videos, podcasts), insurance, info
Best group/forum you’ll join. But read the pinned post outlining the rules! So you want to be a Paramedic?
Oh, and the NHS website about the job.
You’d be an idiot if you didn’t read this too- Taking Healthcare to the Patient (Bradley Report)
Paramedic Evidence Based Education Project (PEEP Report) – looks at education of paramedics and discusses the future of standardisation
(You may need a College of Paramedics membership to follow those links, you can Google them otherwise)
