Hi David,
Right off the bat, this sounds like a spatial reference issue to me. Are the CAD files appearing close to where they should be or are they off the coast of Africa?
I'd try using the CAD to Geodatabase Tool (link below). This will create a geodatabase with spatial reference for the CAD Data.
If the data still doesn't line up at that point, you will probably need to georeference the data. This is a pretty straight forward workflow. Assuming all the schools in your data are off by the same amount (ie not appearing on top of each other), you may only need to do this once and then reuse the spatial reference file you create.

Cheers,
