πŸŽ–οΈ Real Soldiers in the Making: The Khao Chon Kai ChallengeA massive shoutout to our Year 2 Ror-Dor recruits (Batch: 6–8 February 2026)! As we speak, our students have traded air-conditioned classrooms for the rugged terrain of Kanchanaburi, stepping into a true test of grit and resilience.By now, we suspect it’s not just your determination that’s on fireβ€”your faces are probably looking a little extra crispy, perhaps even β€œmedium-rare,” under that relentless sun! πŸ”₯🚩 β€œWelcome to Hell” Survival Checklist:β€’ The Dust: Forget PM 2.5β€”this is PM 100. Thicker than baby powder and clinging to everything you own. πŸ’¨β€’ The Heat: A sun brighter and fiercer than a 10,000-watt stadium light. β˜€οΈβ€’ The Vibe: Homesickness heavier than the charcoal smoke rising from your field rations. πŸ₯˜You may return as the β€œSunburnt Squad,” but those tan lines are more than skin deep. They are natural medalsβ€”earned through discipline, endurance, and mental toughnessβ€”proof that you survived one of the toughest challenges in the curriculum.Stand tall. Wear them with pride.#CISMILITARY #G1_2026 ... See MoreSee Less

As you are aware, the Air Quality Index (AQI) has been at high levels over the past two days, and we are taking this matter very seriously to ensure the health and safety of our students.Please follow our school AQI policy at all times during this period:No students are allowed outdoors without a proper PM2.5-rated face mask.PE classes should be conducted in classrooms and not in the basketball court.During breaks, students should briefly purchase snacks and return to their homeroom immediately.At lunchtime, students should spend minimal time in the canteen and return to class as soon as they finish eating.We appreciate your cooperation in enforcing these measures and ensuring that students adhere to them strictly. CIS now has its own AQI monitoring device connected to AirVisual, and we are closely tracking real-time data to make informed decisions.Thank you for your continued support in prioritizing student safety. If you have any questions or need clarification, please reach out. ... See MoreSee Less
