About Us

California School of the Arts – San Gabriel Valley (CSArts-SGV) is a public charter school that provides a creative, challenging, and nurturing environment offering bright and talented students a rigorous college-preparatory education and pre-professional arts conservatory training.

The school’s unique culture and innovative curriculum allows its students to grow and thrive as artist scholars and to develop their confidence and talents. Small student/teacher ratios in academic and arts classes allow for personalized attention. CSArts-SGV students receive opportunities to participate in master classes, guest artist presentations, field trips, and performances, as well as a variety of campus clubs and activities.

CSArts-SGV is a tuition-free, donation-dependent program made possible through a unique public-private partnership with the Duarte Unified School District. While approximately 10% of students reside in Duarte, CSArts-SGV draws students from more than 80 cities within and outside of the San Gabriel Valley, creating a diverse culture of artistically focused students.

Our History

CSArts-SGV is the first regional campus to open in a network of public charter schools created by the California School of the Arts Foundation. The campus was opened to provide more students with the same life-transforming arts and academic programming celebrated at Orange County School of the Arts (OCSA). In its 30-year history, OCSA has become one of the most selective high schools in the nation. In an effort to serve as many deserving students as possible, leaders at OCSA established the California School of the Arts Foundation, which opened CSArts-SGV on August 14, 2017.

Admissions Overview

After becoming familiar with the various conservatories and the skills characteristic of those conservatories at one of CSArts-SGV’s Preview Days, prospective students are invited to fill out an application and participate in the Conservatory Workshop/Review Process to help them decide which conservatory is the best fit for them. Applicants will then select their desired conservatory for enrollment. Should the number of applicants exceed space available, a lottery is conducted, by conservatory, to determine which students are admitted. CSArts-SGV admits all applicants on a space-available basis.

Unparalleled Value

CSArts-SGV offers an unparalleled value to its bright and talented students through the school’s rigorous academic program, combined with the 10+ hours of weekly intensive arts instruction.

CSArts-SGV is a tuition-free, donation-dependent school, provided through a unique public-private partnership. As a public charter school, CSArts-SGV receives funding from the State of California based on Average Daily Attendance (ADA) to fund the school’s college preparatory academic program.

Private funds must be raised for CSArts-SGV's comprehensive arts instruction. While no student is admitted or denied based on family financial capacity, parents are encouraged to participate in the annual Parent Giving Program, which involves a voluntary, tax-deductible donation to the school. Funds raised through the Parent Giving Program are used to cover all costs related to the arts instructional program, and every dollar donated goes directly toward students' arts conservatory education.

Families are encouraged to actively participate in their child’s education, through financial and volunteer-based commitments. Together, these attributes contribute to the dynamic school culture at CSArts-SGV, which promotes a cohesive educational community for parents, students, and staff.
