“We’re on track” to reopen April 12, San Diego Unified School District Area 5 Superintendent Mitzi Merino told the La Jolla Cluster Association during its March 18 meeting, referring to the district’s plan to have students return to campuses for up to four days a week of in-person instruction in a hybrid model with online learning. At La Jolla High School — which had 1,338 students enrolled as of Feb. 21 — 56 percent of families chose the onsite option. Those students were split into two groups — by last name — to attend classes in person two days a week, Principal Chuck Podhorsky said. One group goes to campus Mondays and Tuesdays, the other on Wednesdays and Thursdays.
