How a Lombok School Expedition Satisfies IB CAS Requirements

Article Summary

Lombok school expedition ib cas. This article explains how a school expedition to Lombok, Indonesia can satisfy IB CAS requirements across all three strands – Creativity, Activity, and Service – as well as key CAS Learning Outcomes including leadership, collaboration, and ethical decision-making. Venture Beyond Expeditions offers three program levels on and around Mount Rinjani: the Sembalun Valley trek, the Crater Rim trek, and the Full Summit. Written for IB Diploma coordinators and Heads of Outdoor Education at international schools considering an overseas expedition program.

Introduction

When a Head of Outdoor Education at an IB school contacts us about a Lombok expedition, the conversation usually starts with the mountain. It should also include the CAS coordinator.

A well-structured expedition to Lombok does not just sit alongside a student’s IB CAS programme. It can anchor it. Our three program levels – the Sembalun Valley trek, the Crater Rim trek, and the Full Summit – each provide genuine physical challenge appropriate to the group. The surrounding community of Senaru offers meaningful service opportunities, and the experience of preparing for and completing a serious expedition develops exactly the kind of reflective, self-directed engagement that IB CAS is designed to cultivate.

This article sets out how a Lombok expedition maps to the three CAS strands, and what schools can build into their itinerary to ensure students leave with strong, evidenced CAS experiences.

What IB CAS Requires

IB CAS is a mandatory core component of the IB Diploma Programme. Students must engage meaningfully across three strands – Creativity, Activity, and Service – over a minimum of 18 months, and must demonstrate evidence of seven CAS Learning Outcomes through documented reflection.

The IB no longer specifies a fixed hour requirement. What matters is that experiences are genuine, sustained, and evidenced through student reflection. A Lombok expedition, properly structured, satisfies that standard across all three strands in a single program.

Activity: The Expedition Itself

The Activity strand requires physical exertion contributing to a healthy lifestyle. It encourages students to step outside their comfort zone and develop a commitment to physical wellbeing.

A Lombok expedition satisfies this strand directly and unambiguously.

The Sembalun Valley trek is our entry-level program, designed for school groups new to multi-day hiking. Students trek through the highland meadows of the Sembalun Valley, building endurance and confidence over consecutive days in a genuine mountain environment. For many students, this will be the most physically demanding thing they have done.

The Crater Rim trek takes students to the edge of one of Southeast Asia’s most dramatic volcanic landscapes. The ascent involves sustained physical effort over varied terrain, with genuine exposure and a demanding final push to the rim. Students who complete this program have earned it.

The Full Summit is our flagship program, reserved for groups with the preparation and commitment to attempt Rinjani’s 3,726-metre peak. It is a serious physical undertaking that requires sustained aerobic effort across multiple days.

All three programs generate strong evidence for the Activity strand. The physical challenge is real, the environment is demanding, and the effort required cannot be simulated. Students know the difference, and so do their CAS coordinators.

Service: Community and Environment in Senaru

The Service strand requires collaborative and reciprocal engagement with a community in response to an authentic need. It must be genuine – the IB is explicit that service is not a box-ticking exercise.

This is where a Lombok expedition has an advantage that most school programs cannot match.

Venture Beyond Expeditions is based in Senaru, a village on the northern slopes of Rinjani. Our local partner, Rinjani Dawn Adventures, founded the Sasak Warriors initiative, which has provided earthquake relief, water, food and medical aid to local communities following the 2018 earthquake, and continues to deliver learning materials to local schools. Our relationships with the Senaru community are long-standing and genuine.

Schools that want to incorporate a meaningful service component into their expedition can do so through us. Options include:

• School visits and teaching: Students can visit a local Senaru school and deliver a presentation or teach a class. This requires preparation before departure, making it a genuine CAS project rather than a passive experience.
• Fundraising for a local initiative: Schools that want their students to fundraise for an education or environmental project in Lombok can have that funding directed to a specific, evidenced community need through the Sasak Warriors network.
• Environmental work on the mountain: Litter collection on the Rinjani trail is practical, visible, and directly relevant to the environment students are trekking through. It connects the Activity and Service strands in a single experience.
• Local farm visits: A visit to a local organic farm in the Senaru area introduces students to sustainable land management and food systems in an Indonesian context.

All of these options can be built into the expedition itinerary at the planning stage. Schools should discuss their CAS Service requirements with us early, so the right activity is scoped and documented properly.

Creativity: Reflection, Planning, and Cultural Engagement

The Creativity strand is the most flexible of the three. It covers original thinking and expression across a wide range of activities, and does not require a traditional arts component.

A Lombok expedition can support the Creativity strand in several ways, depending on what the school builds into the program:

• Expedition journaling: Students who document their experience through daily written or photographic reflection are engaging in a creative practice that directly supports CAS portfolio requirements.
• Pre-expedition research and planning: Students who take an active role in researching the destination, the culture, the environment, and the community before departure are demonstrating creative and independent inquiry.
• Cultural documentation: Students who engage with the Sasak culture of Lombok – its language, traditions, and community life – and produce any kind of creative response to that engagement can document this as a Creativity experience.

We recommend that schools work with their CAS coordinator to identify which Creativity experiences will be most meaningful and evidenceable for their students before the expedition departs.

CAS Learning Outcomes a Lombok Expedition Addresses

Beyond the three strands, IB students must demonstrate evidence of seven CAS Learning Outcomes. A Lombok expedition, depending on how it is structured, can provide genuine evidence for the following:

• Identify own strengths and develop areas for growth – multi-day trekking in a demanding environment is one of the clearest possible contexts for this
• Demonstrate that challenges have been undertaken, developing new skills in the process – the physical and logistical challenge of the expedition speaks directly to this outcome
• Demonstrate how to initiate and plan a CAS experience – students who take an active role in expedition planning, fundraising, or service design can evidence this outcome directly
• Show qualities of a leader in collaborative situations – group dynamics on a mountain expedition, where decisions matter and students must support each other, provide genuine leadership moments that classroom-based activities rarely replicate
• Demonstrate the skills and recognise the benefits of working collaboratively – an expedition is inherently collaborative, and the evidence is lived rather than constructed
• Demonstrate engagement with issues of global significance – environmental degradation on Rinjani, earthquake recovery in Lombok, and education access in rural Indonesian communities are all issues of genuine global significance that students encounter directly on this program

Planning a CAS-Aligned Expedition to Lombok

A Lombok expedition that is designed with CAS in mind from the start is significantly more valuable than one where CAS documentation is retrofitted at the end.

We recommend the following approach for IB schools:

First, involve the CAS coordinator in the planning conversation from the beginning. The expedition coordinator and the CAS coordinator should agree on which strands and learning outcomes the program will address, and what documentation students will be expected to produce.

Second, build the service component into the itinerary at the planning stage. Whether that is a school visit, an environmental activity, or a fundraising project, it needs to be scoped, communicated to students in advance, and reflected on properly to generate valid CAS evidence.

Third, brief students on CAS reflection requirements before departure. Students who understand what they need to document, and why, will generate better evidence. Students who are told to write something up when they get home will not.

Venture Beyond Expeditions can provide program documentation to support CAS portfolios, including itinerary records, service activity descriptions, and guide-verified attendance records. We cannot write student reflections – that is the student’s work – but we can ensure the program itself is structured to make genuine reflection possible.

Three Programs, One CAS Framework

Regardless of which program tier your school selects, the CAS framework applies equally. The Sembalun Valley trek, the Crater Rim trek, and the Full Summit each offer a genuine Activity experience. The service and community opportunities in Senaru are available across all programs. And the reflective, self-directed engagement that CAS requires is built into the expedition experience at every level.

The right program for your school depends on your students’ experience and preparation, not on what will look best in a CAS portfolio. We will help you make that assessment honestly.

Frequently Asked Questions

Can a school expedition to Lombok count as IB CAS? Yes. A Lombok expedition with Venture Beyond Expeditions can satisfy all three IB CAS strands – Activity through the trekking program, Service through community engagement in Senaru, and Creativity through expedition journaling, planning, and cultural documentation. Schools should involve their CAS coordinator in the planning stage to ensure the program is structured and documented correctly.

Which IB CAS strand does trekking satisfy? Trekking satisfies the Activity strand, which requires physical exertion contributing to a healthy lifestyle. A multi-day trek on or around Mount Rinjani provides genuine, sustained physical challenge that generates strong evidence for this strand.

What service opportunities are available on a Lombok expedition? Service options include visiting and teaching at a local Senaru school, fundraising for a community education or environmental project through the Sasak Warriors network, environmental litter collection on the Rinjani trail, and visits to a local organic farm. All service components are arranged through Venture Beyond Expeditions and can be built into the expedition itinerary.

Does Venture Beyond Expeditions provide CAS documentation? We provide program documentation including itinerary records, service activity descriptions, and guide-verified attendance records to support student CAS portfolios. Student reflections must be written by the students themselves.

Which expedition program is best for IB CAS? All three programs – the Sembalun Valley trek, the Crater Rim trek, and the Full Summit – provide a valid Activity experience and access to the same service and community opportunities in Senaru. The right program depends on your students’ experience and fitness level, not on CAS requirements. We will help you make that assessment at the planning stage.
