@LocalzUK - When I said compare it to a company with 100 - 150 employees I was mainly talking about the amount of turnover a company is likely to have. You have to think that a school has a turnover equivalent to its budget and profit equivalent to its non-essential commitments like salaries, heating lighting etc. IT Expenditure would have to come out of the equivalent of profit for the company as it does not make a direct financial return. A company with 600+ employees would have a turnover much greater than that of even a large school.
@Geoff - only certain funding is ring fenced towards IT specifically, and nothing like the amount schools should be spending in order to have the resources they need - so not really cobblers.
