Thanks for your question. As the others have already mentioned, you can check with the Fremont Union High School District office for the actual boundaries of all of the various high schools in the area.
As someone already noted, the zip codes for Homestead High School are: 1) 94087 (West Sunnyvale); 2) 94086 (a small fingerlet that borders El Camino Real from Bernardo to Pastoria) and a portion of 3) 95014 (where the bridge across the freeway meets Mary Avenue on the Cupertino side of the community and the area around the bridge to Hollenbeck).
Cupertino High School's boundaries include zip code: 1) 95014; 2) 95051 (the section of Santa Clara bordering Stevens Creek and 3) 95129, that section of San Jose along Stevens Creek from Lawrence up to almost Saratoga and then from Saratoga near Moorpark)
Remember, however, that Fremont High School also shares 94087, 95014, and 94086, and Cupertino High shares its zip codes with surrounding schools too including the HS in Santa clara, so it's very important to consult the district boundary map if going to a specific school is very important to you.
