Self-Directed Learning

Our school projects allow for flexible pacing as students progress through our challenging college-prep curriculum. Teachers support and coach students as they solve problems, discover their learning styles, and demonstrate their knowledge.

Teachers as Mentors

Every student has a dedicated teacher mentor who guides and advises them and their family through their school experience. Students are part of the same mentoring group through graduation where they set goals, share successes and struggles, and build lasting relationships.

Real-World Experiences

Students develop skills and knowledge aligned with their passions and interests through a program called Expeditions. Students are exposed to job shadowing and take specially-designed electives in music, science, the arts, and more.

Real-World Experiences



“Summit Sierra has engaged and inspired my child. My shy son has grown into a gifted and confident writer and speaker, and discovered he has a deep interest in government and history. He has developed strong connections with his teachers and his peers. Summit’s Expeditions program year has been a huge highlight. Summit met my kid where he was, kept him interested, and gave him the confidence and curiosity he needs to move on to the next step.”
