Your Question states the zipcode 91756 which is the city of Monterey Park but the zipcode on your profile reflects 91765 which is DIamond Bar. Just want to make sure if you are asking about Monterey Park or Diamond Bar. The school your child will attend all depends on where you live within the city as well as his/her grade level (i.e. pre-school, elementary, middle, high school)
Since I'm not sure which city you are requesting, here is a link you can use to help find your answer.
If you have any questions please feel free to ask me
