1. I just wanted math acceleration but they couldn't figure out how to do it. When they finally figured out I wasn't going to drop it they offered whole grade (I know bizarre turn of events but he was a good candidate for that too...I just wasn't asking for it). We thought about it for about an hour and went for it. He moved the next day to the next grade up.

2. He won't be repeating a grade later on. It is possible he might even skip again or compact two grades during middle school. We have discussed that this will give him time to have a year as an exchange student in high school if he wants... But I wouldn't count that as repeating a year.

3. Trade offs...hmmm none that I know.

4. My son's skip took place about 4 weeks into the new school year, but it was out of the blue. We didn't plan it, it just happened.
