One of my daughters went to Ashley Falls and all schools in the Del Mar School district are excellent.( Pretty sure the highest in the county over Poway as well ) They get the required stuff out of the way 2/3 of the way through the year and the last third is spent on advanced material. Yes the Asian kids pull up the API but most of these kids come from well educated parents. The way they get around the 1 teacher to 20 kids class size is they will sometimes have a teacher’s assistant and many times 2 parent volunteers ( who generally hold 4 year or advanced degrees.) Definite advantage to have 3 to 4 “teachers” assisting at all times. The school district also raises quite a bit of money for the foundation which is used for more specialized classes.
