Black Diamond High School is the alternative high school for the Pittsburg Unified School District. It serves students who are 16 to 18 years of age and who are behind in credits. The program delivers a standards-based education, using the same instructional materials as are used at Pittsburg High School. However, small class size (no more than 20 students per class), a supportive environment, a focus on the importance of attendance, an intervention program, and a welcoming family-like atmosphere provide students with an opportunity to refocus themselves, earn credits, and receive a high school diploma. Students are enrolled in four classes initially, but can add more, especially during their senior year, in order to reach the 220 credits needed for graduation. Counselors and teachers work with students to help them develop a plan to earn needed credits for graduation and to provide them with information on programs and opportunities after high school.

The mission of BDHS is to provide a meaningful and measurable, learning experience for all students. BDHS is specifically designed for students who have experienced attendance, behavior and achievement problems. The BDHS community is committed to providing a positive, student centered, safe, and academically comprehensive program that is sensitive to the varied learning styles of all students. BDHS offers an individualized educational program that includes assessment of academic and behavioral needs with resources in: academics, counseling and online learning along with a work readiness training. Our goal is to empower our students to become productive, confident, active and contributing members of their communities.
