I'm interested in your reasoning, Neil; how many grades of technician are you thinking of, and what is the rational behind it?
Are you trying to apply different salaries for each grade, and are annual increments in the offing?
Or are you simply hoping to make distinctions for special responsibilities and (or) skills?
In my experience, five levels of Technician has always been enough:-
1) Junior Technician (trainee)
2) Technician (many of these)
3) Senior Technician (team leader and (or) specialist - highest level at small sites)
4) Chief Technician (overall leader - only one per location, if at all)
5) Master Technician (Greybeard, and rarely seen)
Or, if you prefer:-
2) Technician : Class III
3) Technician : Class II
4) Technician : Class I
5) Technical Manager (Project Manager, or "Engineer")
There you have a clear path for career progression, hopefully based on merit, as well as increased responsibilities, specialist courses attended, and so forth; and tempered (only) by time served.
In many cases (small hospitals, and the like) only levels 2) and 3) would be needed; in situations where a lonely tech was always the only one in residence, level 3) would be preferred. But in most cases ("normal" sized district hospital), we would deploy techs at levels 2), 3) and 4).
We had something like this in Saudi MoH hospitals many years ago, and pay was based on grade (Chief, Senior, Tech), specialisation (eg,
anaesthesia, dialysis, dental, lab, sterilizers, x-ray etc.
) and - it must be said - nationality. As most situations were contractual, with a span of only a few years at most, promotion was, shall we say, rare; although salary increases were not unknown in certain cases. I would suggest that the NHS model is really about career progression and internal Pay Grades.
You will have noticed that I haven't mentioned educational attainments (what we used to call C&G, ONC, HNC etc.
and their international equivalents); but obviously your Job Specs need to mention those somewhere. But something like this is what we used to look for:-
2) Technician : C&G
3) Senior Technician : ONC
4) Chief Technician : HNC
But, I must admit that, back in "my day", we did not place too much emphasis on all that; but rather were always more interested in "hands-on" (and in some positions, leadership) skills.
