Well I was talking about teaching in a classroom and an average student. Over my career, and in my experience, the older students are better. The students who were held back because their parents wanted them to have a maturity advantage were extraordinary. In fact, the best students I ever had. The students who were young for their grade were by-in-large IMMATURE.

Witnessing this in high school students and knowing I graduated at 17 (turned 18 in college), I said I don't want my children to have this disadvantage. I don't have to do a research paper to know it.

Sorry Cardfan1 that you felt disadvantage as fresh in college. I must say however that I disagree that children in their proper grade level are immature,I would argue that the holdbacks have an academic advantage and are easier to teach. Try teaching college!
