DS7 started K early so he is accelerated one year. He’s the youngest second grader at a large public elementary and is doing great. He doesn’t have social or behavioral issues and just qualified for the gifted program for next year.

It would be a poor fit if he were in first grade this year. He’s at the top of his class in second grade. He’d be really bored in first. For him being the youngest is no issue at all.
