The San Dieguito High School District has 5 high schools. Torrey Pines and La Costa Canyon are traditional high schools and attendance is based on where you live.
San Dieguito Academy and Canyon Crest Academy are schools of choice (similar to a magnet school). Anyone who lives in the district can apply to go to these schools and they hold a lottery for enrollment if too many kids want to go there.
Therefore, if you lived in PHR you technically have three public high school choices: Torrey, Canyon Crest, and San Dieguito.
(BTW – the 5th high school is Sunset – a continuation school).
