All students learn the academic and personal skills they need to be truly prepared for postsecondary success and able to pursue their dreams.
Student Achievement -- Above All
Student achievement is the civil rights issue of our time and the reason we exist. Each staff member is responsible for our students’ success.
We disrupt systemic racism and the inequities that limit our students’ choices. We nurture a culture where all staff, students, and families are seen and valued.
We serve students and their families first. Our business is their success.
The High Road
We do the right thing. We are fair and treat folks with respect.
Joy and Humor
Our positive, caring culture supports student and staff success. We like fun. We love to laugh.
We face reality, communicate honestly and respectfully, and hold each other accountable.
Everybody is welcome to talk to anybody. We are open and transparent.
We seek a better way — always. We are engaged in an ongoing cycle of goal setting, action, measurement, and analysis.
We are in this together. We may disagree, but at the end of the day, we support each other 100%.
