Year 12 Step Out of Their Comfort Zones on Residential Trips for CAS

Every year, the Year 12 CAS (Creativity, Activity, Service) trips mark a significant milestone in our learners’ journey in their International Baccalaureate (IB) Diploma. This year, our Year 12 learners split across three distinct locations—West Jawa, Bintan, and Chiang Mai—with a unified mission: to step out of their comfort zones, embrace independence, and make a meaningful impact on the communities around them.

Read on to find out more about how our learners spent their week across Southeast Asia.

Replanting the Rainforest in West Jawa, Indonesia

The West Jawa experience kicked off with an early morning flight to Jakarta, before adventuring to their glamping campsite in Pangrango National Park. After braving a 550m suspension bridge to get to camp, our learners were rewarded with a delicious soto ayam (chicken noodle soup) and local curry.

This trip to Indonesia asked our learners to explore sustainable forestry. They immediately got their hands dirty building a plant nursery from scratch. They spent their days learning how to identify native saplings, collecting seedlings and mastering replanting techniques to ensure the survival and long-term reforestation of the national park.

Learners also spent time with the children and staff of Puncak Manis school, where they completed a wonderful cultural exchange and led activities for the younger children. Whilst some learners ran activities like group art projects, reading and sudoku puzzles, other Year 12s started on construction, helping to build a waste management system and ecobricks using litter cleared from the site. 

The learners in West Jawa also had some time for rest and relaxation, visiting a waterfall and enjoying the local wildlife, including a family of langurs playing in the trees next to camp.

Working with Local Communities in LooLa, Bintan

For the learners heading to LooLa Adventure Resort on Bintan Island, the focus was all about working with local communities to learn more about sustainable coastal living and supporting local schools. Arriving with bags full of donations brought from Singapore, our learners quickly familiarised themselves with their service projects before diving straight into some manual labour.

The core of their service involved learning about and installing a ‘Safe Water Garden’ for a local family, which required plenty of digging, shovelling, and building a small water tower from the ground up. In addition to painting the family’s home, the group gifted water filtration systems to five local families. The community generously returned the favour, teaching our learners local handicrafts and showing them how to cook delicious, fresh banana fritters.

The cultural exchange continued with a visit to a local primary school. Welcomed by a traditional dance and morning aerobics, our Year 12s spent time in the classrooms playing word games, handing out toy donations, and ending the visit with an energetic football match.

To balance out their hard work, the group explored the local marine ecosystem. They went on a scenic mangrove walk, braved rock climbing and a ‘flying fox’ zipline, and spent an afternoon snorkelling and jumping into the ocean with a boom net experience. The week concluded around a traditional campfire, giving learners the perfect opportunity to reflect on the community connections they made over the course of the week.

Sustainable Tourism in Chiang Mai, Thailand

Over in northern Thailand, our learners took on a highly sophisticated CAS project focused on Community-Based Tourism (CBT) in the rural districts of Ban Pong and Mae On. The journey began with cultural immersion in Ban Pong, where learners observed a successful CBT model firsthand and participated in hands-on activities like embroidery, tie-dye, weaving, and traditional snack making.

For the rest of the week, learners lived in seven separate homestays across Mae On, fully integrating into the community by helping host families prepare meals and sharing conversations around the dinner table. They also tackled physical challenges, hiking up a mountain to explore ancient caves, caving, abseiling, and rock climbing across five levels of difficulty at the stunning Crazy Horse Buttress.

Back in the village, learners rotated through local cultural practices—like making paper decorations, preparing traditional salted duck eggs, making soap, and baking Thai desserts—while shifting into their roles as real-world tourism consultants. Working hard in specialised product and marketing teams, they analysed how to make these local experiences sustainable, profitable, and respectful of local heritage.

The trip culminated in a massive milestone: seven of our learners stood up in front of community members and representatives from all eight sub-communities of Mae On. They delivered an incredibly professional slideshow presentation—complete with social-media-style promotional videos they produced themselves—outlining strategic recommendations to help grow local tourism. The week wrapped up with a powerful reflection session at the community centre, where learners shared the moments that impacted them most before heading back to Singapore.

Developing Globally Conscious Leaders

Residential trips like these represent the very best of an experiential education. By stepping away from screens and familiar routines, our Year 12 learners didn’t just fulfill a curriculum requirement—they developed genuine resilience, empathy, and leadership skills. Whether they were planting future forests in West Jawa, engineering clean water solutions in Bintan, or collaborating on professional sustainable tourism strategies in Chiang Mai, they returned to Singapore with a deeper understanding of global citizenship and stronger bonds with one another.
