Surge suppressor is the buzzword you are looking for.  They will help, but 
nothing will stop a lightning strike that is near enough.  The only question 
is how-near.

The wiki page looks good:
Note the discussion about MOVs getting used up.

Some outlet strips include a pair of phone jacks and/or cable TV connectors.  
That's the quick, simple, and low cost approach.  You can also get industrial 
type units at higher prices.  Google has lots of hits.

I'm far from a wizard in this area.

How many schools are you talking about?  If it's more than 2 or 3, it might 
be worth a phone call to one of the non-cheap places to see if they have 
suggestions.   (Or see if they have some documentation on the web.)

These are my opinions.  I hate spam.
