Well, I'm thinking that a gifted child might be more likely to be identified in the smaller school since they would be more likely to stand out. Possibly, as a result of the greater discrepancy, a student might be more likely to be subject or grade accelerated.
OTOH, I think that at the larger school a gifted child would be more likely to find academic peers among their age peers. If several students are performing at a similar level, then enrichment might be more likely to occur. However, because the school is more used to seeing gifted kids, they may be more likely to "normalize" it or even minimalize it, even if your child's needs were above the norm. So, I would think that accelerations might be less common at the second, larger school.
Of course, the wild card issues are always the administrators and teachers. Their beliefs and experience will always trump other factors, I think.
