Gifted programs in public schools are typically aimed at moderately gifted students in the 115 to 130 IQ range. A child who is either above that IQ generally or especially talented in a particular area tends to not be adequately accommodated by public school gifted programs.

To make matters worse, it's quite common for very gifted students to also have issues like ADHD or OCD, which qualifies them for a label of twice exceptional. When I was raising my now adult sons, schools typically wanted to label a child either gifted or special needs and often seemed incapable of comprehending that a child could be both.

I ended up homeschooling and as a consequence I was involved with an online voluntary health and welfare organization for the gifted. My impression was that it was pretty common for people with very gifted or twice exceptional children to homeschool due to frustration with how schools handle such students.

They need custom help that few people are qualified to adequately provide.
