Master your IB CAS reflections with this complete guide. Learn what to include, methods of reflection, and how to build your crucial CAS portfolio for the IB Diploma.

If you checked out last week’s blog on 100 CAS ideas, then you should be well on the way for having some exciting, unique and fun experiences with CAS! But guess what – the fun doesn’t stop there. As an IB Diploma student you are expected to reflect on your CAS projects and experiences. But what exactly are CAS reflections, I hear you ask? Read on for the ultimate guide to producing CAS reflections…
Over your 18 months of CAS, you’ll be expected to produce reflections. These are thoughtful, honest accounts of what you’ve gained by completing CAS experiences. A big part of CAS is how your experiences and projects lead to personal development. The IBO states that students should “identify goals, develop strategies and determine further actions for personal growth”. So, analysing your goals, decisions, successes, problems, and ways of overcoming challenges are a few suggestions of what should be included in CAS reflections. Here are the IBO’s top things to consider when producing your reflections:
Other good questions to consider when producing your reflections include:
I found having a CAS diary incredibly useful. After completing a CAS experience or part of a CAS project, I would write down the date, activity and a few thoughts about what I did and how I had found things. I sometimes used the seven learning outcomes (see below!) as guidance for what to write. By making notes (however brief!) in my CAS diary, this then made my life much easier when it came to producing my detailed reflections. It can really save you time in the long run!
The Lanterna Tip: Purposeful reflection is about quality, not quantity. You are not expected to write detailed reflections after every single one of your CAS experiences. Rather, you should simply identify moments worthy of reflection, such as:
Whilst most of my CAS reflections were written paragraphs, this doesn’t have to be the case. Find forms of expression that suit you and your various CAS experiences. Other methods of reflection could include:
So, if you’re not a fan of writing down your thoughts and feelings, use another creative method to make the process easier and more natural!
Your reflections make up what’s known as your CAS portfolio; this is your evidence of engagement with CAS. It not only includes your reflections, but you can also include images, posters, videos etc. In addition, your portfolio should include evidence of achievement of each of the seven learning outcomes. These are:
Some of these learning outcomes may be achieved multiple times, while others may be achieved less frequently. But you must provide evidence of having achieved each learning outcome at least once through your CAS journey. Read more about each outcome, HERE.
Whilst your CAS portfolio is not formally assessed, it is a crucial part of your IB Diploma. Remember, if you don’t pass CAS, you won’t achieve your Diploma. And that would be very sad after all of your hard work!
I hope this week’s blog will make your life easier when it comes to producing your CAS reflections. For me, a key takeaway is quality over quantity. Purposeful reflection is not about constant reflection after every single one of your CAS experiences, but rather identifying important moments for reflection. Remember, CAS is not meant to be a burden, and neither are your reflections! If you’re not a fan of writing out your reflections, and you’d rather create fun and interactive video diaries, go for it! Think of ways to make the reflective process much more enjoyable!
