For a school website its much better then most there is!
it sure goes in the same line as the microsoft one except a slight color change and being a 1 column layout.
The menu link color is a bad choice though, it needs to lighter or darker beacuse now it's almost blending with the grey background! wich isn't what you want from what I know :P.

I do hope your not speaking of actual html frames as they severely removes accesability for people with screen readers etc. that should be a serious nono for any school website unless you make a splash page with a text version of your site.

Other than that i don't think its anything special and if i remember it right you have done better!
work a bit more on it, try to improve accessability and such.

good job .
