Principal's Message

Dear Castle Rock Families,

Welcome to the new school year at Castle Rock Elementary School! I hope you and your family had a restful and enjoyable summer. As we embark on another exciting academic year, I want to extend a warm welcome to both our returning families and those who are joining us for the first time.

At Castle Rock, we are committed to providing a safe, nurturing, and stimulating environment where every child can thrive academically, socially, and emotionally. In order to align our school expectations, we have adopted the acronym “CRK” to represent Castle Rock Knights as “Caring, Reflective, and Knowledge.” We offer instruction that nurtures the curious mind through local and global connections based on the International Baccalaureate Primary Years Programme.
 
Our dedicated staff has been working diligently to prepare for the year ahead, and we are eager to partner with you in your child's education.
 
If you have any questions or comments, please feel free to talk with your child's teacher or call me directly at the school office.

We are looking forward to a fantastic year filled with learning, growth, and memorable experiences. Thank you for your continued support and partnership. Together, we can make this a remarkable year for our children so that we are “learning today to be a global leader tomorrow!”
 

Go Knights,

Elizabeth Chang, Ed. D
