Yes, we told them, but they were in 7th grade. They also knew that the law in PA is if you have IQ >= 130, the school must provide gifted services. Additionally, they are expected to attend the yearly GIEP meetings, so pretty much impossible to hide it from them. They know kids at the HS and elsewhere who are PG (they are not), so while they know they are "smart", they know kids who are far smarter.
