In the UK this is exactly what the BCS is trying to achieve - complete with [rather painfully high] membership dues. It is held back (I think) by the youth of the IT profession (compared eg with medicine and law) and by the speed of change and innovation. You cannot practice as a doctor or a solicitor without the right professional standing and qualifications, but there is no similar need to be Chartered before you can work as an IT professional. And bright younger people with the latest skills can do it now, as well or better than time-served professionals who qualified with yesterday's skills. Employers want the technically able before those who are registered professionals.

I am describing rather than criticising this situation - there are pluses and minuses - but it is why we still worry that ethics and professionalism are not embedded in IT.
