District 4 Supervisor Carmen Chu will urge the San Francisco Unified School District to completely revamp its school-assignment process — especially with an eye toward sending children to their neighborhood schools — at a hearing today.

Chu’s district includes the Sunset district, where some of the highest-demand schools, including Lowell High School, are located.

The district ran an “instant lottery” Wednesday night for the parents of 23 incoming kindergartners who learned two weeks ago that they’d been bumped from Spanish-immersion classes at Flynn and Alvarado schools.

A competing group of kindergarten parents, still waiting for one of their preferred schools in the fall, are circulating a petition to protest the district’s handling of the assignment situation, according to parent Abigail Marks.
