SD Realtor, Torrey Pines, is San Dieguito schools. Torrey Pines, all the way north to La Costa Canyon, is all the same school district (in terms of high schools).

So basically Del Mar, Carmel Valley, Solana Beach, Cardiff, Encinitas, Rancho Santa Fe, and South Carlsbad (La Costa) are all the same school system, much like RB, Poway, RP, and Mt. Carmel are all Poway schools.

There are also smaller, lottery type high schools (Canyon Crest, and San Dieguito), but basically anyone living in the towns mentioned are tied to either Torrey Pines, HS or La Costa Canyon, HS.
