Sounds to me like your school doesn't HAVE an authentic GT program, and they aren't happy that your little camper isn't willing to march and sing with the other campers and pretend that it IS the real deal...
Have you asked your DS why he thinks his performance has been, er-- lackluster?
These are the things that stand out for me in your post:
entrance scores were "rare" for their population.
school offers little differentiation and they have already said they won't subject accelerate
won't do math or science in his gifted class
Most of their work follows this model: look something up and record it in some manner
Sounds to me like this is merely the 21st century version of "send the disruptive (GT) kids to the library so that the rest of the class can learn something..."
{sigh}
What are your other schooling options like?
