We have resisted offers of full grade acceleration in part to avoid early college. My kids are not unusually mature for age, and my preference is that they start college with age-peers, even if that means being a bit ahead when they start.
However, one of my tenth grade twins has discovered that he can graduate one year early, due to getting high school credit for taking geometry and algebra in middle school. If he succeeds in getting admitted next fall to a college he really wants, I will support early college.
