Philippines Department of Education implements four-tier heat response system

The Philippine Department of Education (DepEd) has issued Memorandum No. 64, series of 2026, establishing a four-tier response framework to protect students and staff from extreme heat. The policy, signed by Education Secretary Sonny Angara, introduces a tiered system ranging from 'Hayo' to 'Hinto' to address rising temperatures expected during the 2026–2027 El Niño episode.

Under the new guidelines, schools will adjust activities based on specific heat index levels. At Level 1 (Hayo), face-to-face classes continue with adjustments like water breaks and shaded activities. Level 2 (Hinay) allows for modified schedules or hybrid learning. Level 3 (Hinga) mandates the suspension of face-to-face classes when the heat index reaches 33 to 41 degrees Celsius, replacing them with learning packets. At Level 4 (Hinto), all school activities, including home-based learning, must stop once the heat index hits 42 degrees Celsius.

The framework shifts away from a uniform national approach, granting school principals the flexibility to make decisions based on actual classroom conditions rather than general weather reports. DepEd has also directed schools to conduct environmental audits to assess facilities and essential services in preparation for the anticipated 'super-El Niño'.
