Here is the AfC web site with lots of useful links and
here is the AfC handbook that gives you all the guidance for assessing job descriptions.
Remember the qualifications are also "or equivalent". Ward sisters tend to be band 7 but how many have a masters degree are even first degrees for the older ones?
Have a look at the Healthcare Scientist job profiles
here. The section has
Medical Technology Technician profiles from band 4 to band 8b.
Make sure your JD has all the right buzz words to match the grade it should be.
