On Monday, March 30, 2020 at 5 AM PDT the Monthly Calendar, Grades, and Reports Card widgets will be disabled in the Portal to help further improve performance. Students and Parents will still be able to access that information through the individual Class. Currently, we do not have an estimated time as to when they will be brought back. Updates will be provided as soon as they are available. Thank you for your patience. Our apologies for any disruption this may cause.
