Thanks for all your contributions - even those who couldn't resist bringing secondary schools into the discussion! :p
It's clear that most of you consider complex password for infant children unnecessary and undesirable, and I can see your point. My problem (and I'm acutely aware of it) is that I have worked in the financial services industry for (way) too long and am used to a completely risk-adverse culture whereby you normally need DNA samples to log on :) I accept that the school environment does not require such strong security measures, although I am still slightly concerned around data protection. Being able to log on to the school's network so easily is a gift for anyone attempting to gain access to school records etc.. I know it's a "closed network" to the extent that there are inherently physical access controls (locks on the doors!) in place, but it still niggles ... guess I'll just have to get over it :)
Re keeping the children's work secure ... my understanding is that now that ICT is becoming a core primary education subject, there is increasing emphasis on monitoring and assessing the child's progress in ICT, which means being able to keep a "portfolio" of work as the child progresses through the school. Therefore, other children saving their work in the wrong folder etc. and confused ownership will become a real issue, if it isn't already. Certainly, at my school, my ICT Coordinator is already pulling her hair out because she knows some children's work has got mixed up.
Anyway, thanks again all for your comments ... keep them coming!
