Principal's Message

Welcome to Castle Rock Elementary School where our goal is to be a school that nurtures "...students to become critical thinkers of today and global leaders of tomorrow.”  I am pleased to be the principal of a school that believes that all children can learn at the highest levels and strives to put them first in all we do.  We believe that all children must be supported and challenged to develop academically, socially, emotionally and physically, and our many programs here at Castle Rock endeavor to empower this growth and development.
Since 2006, Castle Rock has been an International Baccalaureate (IB) school.  The IB Units of Inquiry weave seamlessly throughout our teaching and learning, and provide opportunities for student growth in oral, written, and visual communication.  Our teachers incorporate the California State Standards into the IB Primary Years Programme and across all subject areas.  Our goal is to construct meaning through teaching using the trans disciplinary skills of communication, research, thinking, and self-management.  These skills are used to shape learners who incorporate the IB Learner Profile of "being", including being caring, a thinker, a risk-taker, knowledgeable, balanced, an inquirer, open-minded, a communicator, reflective, and principled. We also believe strongly in student agency and voice, and encourage our children to take action and promote change on and off our campus.  Those who take a walk through our campus are bound to see evidence of student agency all around.
This year we will continue to focus on developing global learners who are possess the skills of the 21st century.  A continued emphasis on STEM education, critical thinking, cooperation and collaboration with others will drive curricular initiatives.  We thank our learning community for their ongoing support in these endeavors, as only true partnerships between school and home will result in lasting success for our students. 

I look forward to working with students, staff, parents and our community this year!  We represent a unique learning environment that helps students to develop into responsible, global citizens ready to make an impact on their communities.  See you at the Rock!
