My twin daughters go to Oster since Kindergarten and now they are in 3rd grade. We love oster community. I really hope that the new principal is also as friendly as Mr. Martino
—Submitted by a parent
The school has a real sense of community with the teachers and parents working together to help a very diverse group of kids. Positive attitudes and appreciation all around.
—Submitted by a parent
My kids attend Oster elementary. Overall the teachers are good. But I am disappointed about the administration and curriculum. No P.E. no art class, music class only once a month due to the budget cut. The current principal is very difficult to communicate with. It's sad to see many good families are leaving. I think our children deserve better education.

Though now in middle and high school, all 3 of my children attended Oster from Kinder through 5th grade. My oldest is off to UC Berkeley in the fall. The education they received through our public schools in this district have been exceptional. Teachers are dedicated and caring, leadership (both parent and administration) is effective, and the community is involved and proactive.

My daughter transferred in when she was in fourth grade. Her teacher was incredible, and my daughter flourished. The private school education my daughter had received from Pre-K -third grade was good, but I have to say, her experiences in fourth and fifth grade at Oster were phenomenal. Oster exceeded my expectations; for that, I am truly grateful!

Wow! This school is the best! We have a fifth grade student and a third grade student and we have been here at Oster since kindergarten. We love the school and the teachers. The school has a great GATE program. I am a very active parent and the school and classrooms welcome the help and support. The test scores are high and getting higher!

This school has fantastic parent involvement. There are always lots of after school/ outside of school activities. Small town atmosphere in Silicon Valley.

January 2006- This school is great, however I have observed that it is a little behind in some things. They still have lunch tickets instead of the electronic lunch card system (almost like a credit card) to make it easier on both student and teacher. This years teacher is o.k. but I think she can improve on motivating the students a little more. My son seems to be a little bored sometimes and makes him feel like he does not want to go to school. The academic program seems to be working very well, he brings home homework and does lots of writing in class. He is doing very well in Math too. Two thumbs up for Oster.
—Submitted by a parent
My 2 children love this school. The parents and staff make it feel like family there. I really love the integration of sign language in each class. My children will be bilingual by the time they leave Oster!
—Submitted by a parent
Excellent academic programs and tremendous extracurricular activities including band, dance, chess, science and computer club. Great parent involvement, Xilinx partnership and Washington Mutual partnership. Undergoing renovation summer 2005.
—Submitted by a parent
This is a wonderful elementary school. The enrollment seems lower then most schools in the Union School District because of the mature (older) neighborhood. My son has received an excellent education here and has matured and improved academically each year. The teaching staff is exceptional! My son praises his teachers daily! He has been attending this school from 3rd to 5th grade and has the very BEST TEACHER (by far) in the school district! The teachers make learning fun and motivate the students to strive to do thier best without compromising their high standards. I am very impressed with this school overall.
