Summary

Diamond Technology Institute (DTI) is a small, standout public high school serving about 87 students in grades 9-12 within the generally lower-performing Pajaro Valley Unified district in Watsonville, CA.

DTI excels in several key areas, particularly in English and Science, where its student proficiency rates significantly outshine nearby schools like Aptos High and Watsonville High, and even beats the state average. The school is exceptionally effective with its student population, boasting a strong 95% graduation rate and very low chronic absenteeism. Interestingly, it achieves these strong results while spending considerably less per student than other high schools in its district.

A notable challenge for DTI is mathematics, where proficiency is low, similar to other area schools with comparable demographics. When compared to other small, alternative schools in the region, such as Renaissance High Continuation or New School Community Day, DTI's academic performance is far stronger, proving that its specific model is highly effective. Overall, DTI is a high-performing school that successfully supports its students toward graduation, with clear strengths in literacy and science instruction.
