I think API (score) wise, it mainly depends on the asian student percentage, the higher the better. You can see asian family cramped in Pacific Highland Ranch, and all new communities south of 56 in CV, so it’s no wonder why CV school doing good. Similarly, if you look at 4S an Del Sur, more and more asian families moving in, it’ll not only stablize the housing price but also boosting the school reputation IMHO.
