Typical uses of IT in schools

Hi all, What does everyone on this list (and I know there are IT managers for schools in here) typically identify a schools requirements for IT? Do schools typically need to use productivity software such as word processors and spreadsheets or is there more customized software in use (educational titles and such like). AllI can remember of school was a large proportion of work done in productivity applications (MS Office), and not really any custom applications. Cheers, Jono
