It's a relatively basic introduction but it's a little out of date with some of the numbers, particualrly in relation to the numers taking the Diploma. Nevertheless it's a very good introduction to the subject and it does cover all the angles from university to employers to equivalence.
Recommended if you need to know more or indeed need to help colleagues know more.
