OSS CORE VALUES

Students identify their strengths, work on their challenges, and strive for accuracy in pursuit of academic and personal excellence.

Excellence

OSS students learn to value all ideas and identities, support others, and engage in open discussions, “seeking first to understand, not to be understood.”

Community

Civic Engagement

Through civic engagement, OSS students learn to identify community needs, conduct research before action, and take the initiative to support their school and local community.

Leadership

OSS empowers students to become strong leaders by guiding them to think flexibly, seek mentors, and to find the courage to speak up for what they believe in.
