You need a Level 4 Course which includes 450 hours of classroom training, 100 client hours and your own personal counselling in order to join the BACP, who are one of the biggest, but not the only membership body. Most non-counsellors know and look for BACP.
If you do not do a BACP accredited course, you will need to take a Certificate of proficiency this is a multiple choice question test and it will take 5 weeks to be marked and come back to you. Then you are a confirmed registered member, with the increase in fees and can list yourself on the BACP list.
Costs to consider:
Training fees probably at least £6k to get to level 4 It will take at least 3 years, longer and more expensive if you consider a degree.
Supervision £65 a month if not included in your placement
Insurance Costs
Membership Costs
Time needs
On top of training, once you are at level 4 you will also have your own personal therapy, counselling placement, supervision which is 1 hour for every 8 client hours, so it can soon mount up.
Also consider that your studying and all of this is going on whilst you need to juggle work and family.
Once qualified you then realise no one wants a newly qualified Level 4 and so you spend more on training further, or you keep volunteering for free until you gain enough for accreditation (2yrs post qual)
