DLSZ’s Vision Mission (VM) Week is moved to November 23-28, 2015 to give way to the NO CLASS days in Metro Manila from November 17-20, 2015.
President Benigno Aquino III. initially declared November 18-19, 2015 as a non-working holiday as per Proclamation No. 1072. Anticipating the traffic congestion during the APEC week in the Metropolis, DepEd has issued a Memo dated August 10, 2015 announcing the suspension of classes on November 17 & 20, 2015.
Here’s the link to the Department of Education’s (DepEd) Memo on latest development in the suspension of classes during APEC:
Memo from DepEd, Division of Muntinlupa City
To enable the students to make-up for these no-class days, the teachers will be providing them online modules via the Notes & Homework page on the school website.
