Amazing Experience!! Just switched from PUSD to WUSD. What a difference a school can make. Only two weeks in and I'm blown away with all aspects of the school.

If you are looking for a school that still has programs such as PE, Computers, Library, Art, Music, and foreign language this is it. Kids even learn cursive here. Awesome group of teachers who give it their 110%. You wont regret it. IB program is intellectually superior to rote memorization. Do your research and see how an IB private school will cost you 12,000 a year but here its equal access to all kids.

If you are looking for the best elementary school within the Walnut Unified School District, Castle Rock Elementary wins hands down! This is an IB School and you can see the enrichment from this education system flowing through the staff and the smiles from the parents, but most of all the happiness that show on each and every childs face! Learning has been made fun! The teachers work together as a team and support each other, and with a great Principal who really does care about helping and supporting your child, this really is the best foundation for your childs first experience of school. Great API scores and happy kids.

I love Castlerock Elementary !! My daughter has been a student there for the past three years and I am very pleased to see the academic and social progress she has made. This school is academically challenging, however is able to provide the students with numerous fun activities that motivate them to love going to school every day. The IB program is excellent and has helped my daughter become a very well rounded and socially responsible young lady. You always feel very welcome when you come on campus. It's a family atmosphere, parents are very involved with making this school a great place. Mrs. Brown is a great Principal who is supported by a staff of wonderful teachers !!

Love our principal Mrs. Brown and our IB coordinator Mrs. Vera. They are approachable and strong at the same time. It feels like a family here. I appreciate the blend of academics and IB attitudes such as respect, empathy, cooperation, and inquiry. The community club is organized, enthusiastic and diverse. The teachers here have alot of experience and knowledge.

Castle Rock Elementary School should be a good school in a nice Diamond Bar community.

Entire school is participating in the IB program. Parents are not given the opportunity to waive participation for their child. Particiaption should be optional, as it is in the local high school.

We do not like the principal. Twice he has shown really poor judgement.

About the tests


In 2012-2013 California used the California Standards Tests (CSTs) to test students in English language arts in grades 2 through 11; math in grades 2 through 7; science in grades 5, 8 and 10; and history-social science in grades 8 and 11. Middle and high school students also took subject-specific CSTs in math and science, depending on the course in which they were enrolled. The CSTs are standards-based tests, which means they measure how well students are mastering specific skills defined for each grade by the state of California. The goal is for all students to score at or above proficient on the tests.
