Jellyb,
Every district has their own policy for Gifted education and acceleration. For HG kids, challenge classes may not be enough anyway and I would request for acceleration.
I don't know how many tests your DS has to take. My DD10 will have to take 7th grade, 8th grade, Iowa Algebra readiness test and 8th grade TEKS test before admission to Algebra I.(That is the district policy so she has to do it).
I am sure your DS will choose to take the test than bored stiff in regular 6th grade class. Check the district policy and talk to the Gifted Coordinator if they have any. The more you know about what can be done, the better chance of success in your advocacy.
