One thing that I feel throws panels when Job matching (and I am a matcher) is that the list for Specialised Med. Eng. is not exclusive, but if Renal, Annaesthetics etc. is not in the job description then Band 5 here you come.
The requirements for factor 2 could be clearer ie What is 'experience at diploma level' for a profession that is, by definition, practically based? I am hoping (!) that these may be corrected when the promised modified profiles are released (ok - I'm an optimist).
