Check with your Realtor. They'd know - by knowing the general area, and then check with the district.
However, you might want to be a little careful about buying homes in Fremont due to schools.
My brother lives there for years, first bought the house due to the schools - Mission S.J, and then the district got re-zoned, they built a new school around his house, He saw house price dropped $100K overnight. The new school is finally catching up with the old school so he is seeing steady increase to be equal to the homes in Mission SJ. area.
I just heard them (brother, niece and nephew) said that Fremont is looking into busing the kids to different schools to create equality in the school quality. So, that's a new twist for the home buyers/sellers when talking about which school a house belongs to in Fremont.
Be careful are the words.
