I like your list Dottie. I see a lot of parallels with my DS.

1. DS has been asking to go to K since he was 2. He was not satisfied with preschool. At age 3 he told me, "I'm tired of preschool. I would rather go to medical school." He was eager to move up for both of his skips (PreK to K and K to 1st). He has a streak of ambition that you wouldn't expect in a young child.

2. He is outgoing and loves adult interaction.

3. He prefers older playmates.

4. He doesn't panic in new situations, he does his best to figure things out on his own. My DD could not have handled an early skip. She was hanging on by her fingernails just to handle first grade at age 6. By that I mean dealing with spilled drinks at lunch, being scared of fire drills, being dropped off without crying, etc.
