I'd say we had the opposite reaction of syoblrig. The school, sort of unofficially, encouraged us to get testing. Once we had the IQ results and shared the general percentile via email, without ever sharing actual numbers or the report, they then did several assessments, ending with the KTEA, which they had previously said they were unable to do.
All of this helped to get a skip and further subject acceleration with their blessing, which we'd originally been told had only been done once in over a decade. IMO, it was the achievement test scores and the one-on-one interactions the testing led to which caused them to look further at what DS would need, rather than working from generalities about what "typically works" for gifted kids, which had left him rather bored this past year. Good luck!
