The “Mites” programs for which I worked all were associated with top universities, and a number of those kids did take college courses there early. Not at community colleges. Not a one over a long period of time.
However, most of these kids did not end up going to highly selective colleges, either. A lot of them finished early as commuters. Perhaps because of their younger ages, their parents did not want them goingvaway to school. Many finished college very early too. I know several who went to Pace Law school after college and graduated still too young to take the bar! One kid I know isn’t even 20 and hitting Broadway with her college degree completed. She went to Bowling Green for an early program. Could have had her PHD in two more years had she continued with it
There are a lot of non traditional paths out there. I also urge the OZp’s don to look at Soka college, Minerva University and Deep Springs. All three very much off the beaten path.
