Sa pagsisimula ng pagdiriwang ng Buwan ng Wika 2026, buong pagmamalaki nating ipinakita ang ating pagmamahal sa wikang Filipino at mayamang kulturang Pilipino sa pamamagitan ng pagsusuot ng ating mga kasuotang Pilipino.

Ang bawat barong, baro’t saya, Filipiniana, at iba pang tradisyunal na kasuotan ay sumasalamin sa ating pagkakakilanlan, kasaysayan, at pagmamahal sa ating bansang sinilangan. Sa temang “Wikang Filipino at AI: Kasangkapan sa Pananaliksik at Tulay sa Yaman ng Impormasyon,” nawa’y maging inspirasyon ang pagdiriwang na ito upang patuloy nating gamitin, pahalagahan, at paunlarin ang ating sariling wika kasabay ng responsableng paggamit ng makabagong teknolohiya.

Maraming salamat sa lahat ng mga g**o, kawani, at mag-aaral na nakiisa sa pagbubukas ng pagdiriwang. Sama-sama nating ipagpatuloy ang pagpapayabong ng ating wika at kulturang Pilipino.

Mabuhay ang Wikang Filipino! Mabuhay ang kulturang Pilipino! 🇵🇭💙❤️💛

BUWAN NG WIKA 2026

“Wikang Filipino at AI: Kasangkapan sa Pananaliksik at Tulay sa Yaman ng Impormasyon.”

Sa pagdiriwang ng Buwan ng Wikang Pambansa 2026, sama-sama nating ipagdiwang ang kagandahan, kasaysayan, at kahalagahan ng ating wikang pambansa. Patuloy nating yakapin ang makabagong teknolohiya tulad ng Artificial Intelligence (AI) bilang katuwang sa pananaliksik at pagkatuto, habang pinahahalagahan at pinauunlad ang ating sariling wika at kultura.

📢 Inaanyayahan ang lahat ng mga g**o, kawani, at mag-aaral ng Mataas na Paaralan ng Ramon T. Diaz na magsuot ng Kasuotang Pilipino sa Lunes, Agosto 3, 2026, sa ating Flag Raising Ceremony, bilang hudyat ng pagbubukas ng pagdiriwang ng Buwan ng Wikang Pambansa 2026.

Makiisa, magsuot ng ating tradisyunal na kasuotan, at ipagmalaki ang pagiging Pilipino!

🌿♻️ANOTHER DAY, ANOTHER PICK UP FRIDAY ♻️🌿

Small actions create a big impact! 💚

The YES-O officers and members actively participated in another Pick Up Friday (July 24, 2026), collecting plastic waste around school campus as part of our commitment to promoting a greener, cleaner, and more sustainable learning environment.

By working together and practicing environmental responsibility, we help protect our campus and inspire others to reduce plastic pollution. Every piece of litter picked up is a step toward a healthier future for everyone.

🌱 "Clean surroundings reflect responsible hearts." Let us continue to care for our environment—one plastic at a time!

Note: RTDNHS has utilities that maintain the cleanliness of the school ground. The YES O renders assistance as part of its advocacy for a greener and cleaner surrounding.🌿🫶

Be greener. Be cleaner. Be an

"One Tumbler, One Change"

Plastic is everywhere — in our bags, in our trash bins, even in our oceans. But change starts with one simple choice.

That’s why the YES-O Officers of Ramon T. Diaz National High School conducted a campaign and advocacy on Project TUMBLER to encourage every student to bring their own tumbler to school.

It may seem small, but imagine this: If 1,000 students use one tumbler instead of 1 plastic bottle every day, that’s 1,000 pieces of plastic saved. In one week, that’s 5,000. In one school year, that’s thousands of plastics that will never end up in our canals, playgrounds, or landfills.

Bringing your own tumbler is more than just a trend. It’s discipline. It’s responsibility. It’s caring for our school and for the environment we share.

To every RTDNHS student: You have the power to make a difference. Refill. Reuse. Repeat.
Let’s prove that youth can lead the way. Let’s prove that small habits create big impact.

Start today. Bring your tumbler. Be the change.
Because a greener RTDNHS begins with YOU. 🌱
Be greener. Be an
