I wish I knew more about the UK social work diploma. I've been told by the GSCC that the US BSW degree is too general and therefore they need you to have some actual experience on top of that to become registered or you have to go on and get your MSW, and then you can apply right after receiving the MSW...which is what I did. Or am currently trying to do.
But anyway, I want to look into the coursework/practicum involved in a UK social work diploma, just for curiosity's sake. Because in the past, I thought UK social work diploma holders were an automatic acceptance to the GSCC register, but if the diploma holds less weight than the degree... I can't see where the strictness with the BSW is coming from, unless the newly mandated UK social work degree is more involved than a US BSW degree...
My head aches trying to understand the red tape.
From my point of view, to understand UK education in relation to social work, there is the Certificate of Qualification in Social Work, which ended in the early to mid 90s and was replaced by the Diploma in Social Work. Both qualifications are less than a degree. The DipSW was replaced in the 2000s by a BA / BSc (Hons) Social Work and a MA / MSc in Social Work. An honours degree is a single subject degree, usually for three years. You study only that subject. Of course, the purpose of the GSCC is to verify the qualifications which determine ability to practice social work. Hence, all English qualifications, and likely British / Irish ones are likely to be recognised by default because they are the culturally inculacated appropriate social work course of study. And social work is a culturally laden profession.
Undergrad social work degrees in Canada and the US tend to have 2 years general study (psychology, women's studies, social sciences, etc.) before specialising in social work in the final two years. So that would be two years specialisation where a British degree is 3 years specialisation - the onus is to prove that the first 2 years of study relates to social work and how it does so.
Plus, practice placement requirements are not the same, in terms of number of hours or days: UK Bachelors and Masters require 200 days of placement, usually 100 days for 2 placements, one being governmental. This is often much more than US / Canadian placement requirements. If you have done a BSW and a MSW, likely, if you add up number of placement days, it should be equivalent to or more than 200 days. I think under the DipSW, the total number of placement days was less, like maybe 180 in total, but I am going from memory....
Hopefully that explains the situation a little better?
