Schools should not be based on IQ levels simply because it does not analyze all aspects of learning capability as well as emotional maturity. If a child is exponentially brighter that his or her peers, the school should supplement that child's intelligence though gifted programs, rather than assign a higher grade level. Doing so would allow the child to grow intellectually without forcing them to adapt to social situations that are beyond their emotional capacity. Placing a ten year-old in ninth grade would introduce them to teenage problems that they would be inept to handle, such as pressure to use drugs and engage in inappropriate behaviors. A young child would also sacrifice their childhood and deny themselves the time to just be a kid, without all of the stresses that come along with being a student in higher grade levels.
I am for the fact that schools should be based on IQ levels! In fact they do analyze all the levels of intelligence! THey also help you move up in school and the students in the gifted school will learn more instead of having to share a class with people who have a 20+ IQ point difference
An IQ test does not analyze an child's rate of learning, mental capacity, or emotional maturity. Although one might argue that school is not a place for socialization, a child who is exceptionally bright and is placed in a class with kids older than him or her, he would be an easier target for bullying because of his innocence. In turn, the child being bullied may not be able to keep up with their schoolwork because of the torment they are receiving from their peers.
