Not significantly.  All this shows is that the data to be imported is 
likely incomplete, i.e. there are a significant number of schools not 
included.  It does not give any indication if the items in your data 
set actually exist in reality or not.  Since you cannot tell this 
reliably from imagery alone this requires on-the-ground evaluation.  If 
you don't evaluate the data in advance regarding this you will likely 
end up with a significant number of phantom schools that only exist as 
the result of a bookkeeping error of some sort.  Experience from past 
imports tells that this kind of error is very persistent and 
significantly affects the map usability in the long term or in other 
words incorrect information in the database is much more harmful than 
missing information.

On a general note: Usually this kind of assessment should be made very 
early in the planning stages of an import.  From someone like you who 
has already proposed a significant number of imports here in the past i 
would expect this to happen naturally meanwhile.
