Level Up! Learners Today, Leaders Tomorrow.

William Collier Elementary School proudly serves students in Transitional Kindergarten through Grade Five in the Wildomar community. Since opening in 1998, our Comets have been guided by high expectations, strong instruction, and a commitment to educating the whole child.

With the support of our dedicated staff and families, Comets engage in a rigorous, standards-based academic program enriched with arts and band opportunities. We are proud to provide social-emotional supports, including a school counselor and SEL services, ensuring every Comet feels safe, supported, and ready to learn.

William Collier Elementary offers a full continuum of Special Education services, including Speech and Language Therapy, Occupational Therapy, Physical Therapy, Adaptive Physical Education, Resource services, and full-day special education classrooms. We also offer EXCEL, our before- and after-school program, to support Comet families beyond the school day.

Together with our families and community partners, we inspire Comets to grow academically, socially, and emotionally—preparing them to shine today and lead tomorrow.
