We are in a high performing district (like 40% gifted), the classroom is taught to the 90th percentile, but still there is a wide range of abilities. I would say your experience will depend on your class size and your teacher's ability to differentiate. We had 29 kids so I felt like our kids' needs weren't served (as the teacher put it, "I have 28 other kids so there is a limit to what I can do.") So while my kids had peers at their level, they weren't taught at their level.
