Lincoln High has come to represent everything that troubles large urban high schools: continuous staff turnover, lagging test scores, eruptions of violence and students segregated by race, poverty and language. This year, Lincoln will get a new school board trustee and a new principal. Both leaders will face the improbable task of reversing decades of low performance and low expectations for students at San Diego Unified’s most embattled campus.

A few years ago, the San Diego Unified School District adopted a plan to improve academic achievement for black students. But despite years of task force meetings and buy-in from a handful of schools, the plan was never fully rolled out districtwide. Now, the district appears to be either overhauling the blueprint or scrapping it altogether. Meanwhile, it’s moving forward with a new plan to build a coalition focused on equity.
