Sierra School of San Diego is where students with academic, emotional, and behavioral needs uncover their potential through individualized learning that goes beyond what most classrooms can offer. In our private day schools, we meet each student where they are.

Smaller class sizes and high-quality, student-centered instruction allow our teachers, therapists, and staff to build strong connections with each student in nurturing, respectful, structured, and positive learning environments. Drawing from a comprehensive range of specialized services, Sierra School educators implement Individualized Education Programs (IEPs) to help each student shine—at school, at home, and in the community.

Our students benefit from SESI’s Integrated Multi-Tiered Systems of Support that:

    • Individually support each student’s academic, behavioral, and emotional needs
    • Prevent barriers to learning in our classroom environments
    • Connect our team with students, staff, families and district partners to ensure the growth of essential skills outside of the classroom setting

Through evidence-based, data-driven instruction that is aligned with your student’s strengths and IEP goals, we meet your student where they are. In other words, we do not tier your student, we tier our supports to uniquely meet your student’s needs.

Strong relationships with our students, families, and school district partners are our highest priority. Together, we shine a bright light on the possibility and untapped potential of every Sierra School student.

Related services offered at this school include BCBA (Board Certified Behavior Analyst), counseling services, speech-language therapy, transition and life skills program, and occupational therapy programs tailored to student needs.
