I agree, I just don’t think it matters in the 3rd grade. Find the high performers in middle school and high school. If there are students that really need help earlier than that, or have learning disabilities they can either be pulled out, or given extra attention if possible, maybe a tutor. I’d lean towards a bit of extra attention. And yeah, it’s definitely a chip on my shoulder, it’s a motivator for me. When someone tells you you’re not smart, you can accept it or prove them wrong.
