Where should schools spend their money?

In the current economic climate this question has been more pertinent than ever when it comes to a school's investment in ICT and technology. If you work for a state school, the demands on government money are greater than ever and when budgets are tight, technology investment falls quite far down the list. For private institutions which rely on pupil numbers for funding, drops in student numbers have led to similar financial pressures. Therefore the question of what technology to invest in has become an essential one which haunts every budget holder.
