Three Los Angeles Unified School District high schools are starting school today as part of a new shortened summer schedule adapted by LAUSD.
Arleta, Sun Valley and Francis Polytechnic high schools are starting classes today using the "Balanced Traditional Calendar," according to a LAUSD statement.
Classes will now be broken up into two 90-day sessions with six-week breaks in between the sessions, the statement said.
Other LAUSD schools also are moving up their class start date.
Next Monday, 17 other LAUSD high schools and one elementary school are scheduled to start their school year.
The change to the new calendar is to maximize retention between school years, according to the press release.
"The two calendars ... minimize 'summer learning loss,' an erosion of knowledge and skills during the long break from the classroom," the statement read.
