It sounds great.
Did they discuss how they will have everyone do the same topics at the same time with a population selected for interest but not aptitude? It seems they'd have even more problems with pacing than a standard classroom. And to inspire passion, would they not want to follow the interest of a given student/group of students rather than being restricted to the topics the whole school is doing that month?
IME with elementary school kids they need to account for level, pace and processing speed when dividing into math groups which means one group of kids working at a fifth grade level in August gets divided into at least four groups (normal/fast pace, normal/slow processing speed). And these are kids within 2 sd IQ of each other.
I might go and look at their website, that's probably the place to answer my questions.
