It shows how far top of the scale Band 2 is from Band 5. A 2 pay point rise hardly get you half way down Band 5.The rest is a suggestion to get people in for a few years to get your numbers up.TWR and APP radar controllers who are OJTI do not need assessment.You either validate or don't.I don't think it's out of order but it's NEVER going to happen.It's a good way to help your dwindling staff numbers out with some experience.Plenty companies in the big bad world do it.Who's short of staff?
Mind you my replacement probably hasn't started at the college yet.

Ps OK I'll just take the Nats car loan.
