I'd be delighted not to get involved in it but isn't this going to be Compulsory?
No - it can't possibly be compulsory for everybody - how can you be involved if you're considered by your peers, i.e. those included on the VRCT, not fully qualified (
as a Clinical Technologist)?
As a result, through no fault of your own (unless you just refuse if you are eligible for VRCT/HPC) if your employer can't give you a job title of Clinical Technologist, because you're not been on the VRCT or eligible to be included on the HPC register, you will have to be supervised by fully qualified individual in that case I suppose. And given a different job-title I suppose (or keep the one you have if it's not protected).
HPC regulation is mandatory for those
given protected titles - in future (if it materialises) not being considered fully qualified under HPC regulation, i.e. not on the HPC register, then how could you be given such a title by your employer (who has to meet mandatory requirements)?
You will probably remain where you are supervised by others considered to be more qualified than you, irrespective of your previous career choices, or sadly, ability in electronics (we do not all just fix kit) - your choice. I'm only guessing how things will be implemeted in the future but this is likely given the way other regulated profession seem to operate.
Not everyone is going to be required to have a protected title. So why worry if you're not eligible for VRCT. Maybe you should wait and see what happens if and when HPC regulation is implemented.
