The CAS stages (adapted from Cathryn Berger Kaye’s “five stages of service learning”, 2010) offer a helpful and supportive framework and continuum of process for CAS students as they consider what they would like to do in CAS, make plans, and carry out their ideas. The CAS stages are applicable to the three strands of creativity, activity, service, and the CAS project.
These CAS stages represent a process and sequence that can assist students in many aspects of their life. They follow a process whereby they investigate an interest that often raises questions and curiosity, prepare by learning more, take some form of action, reflect on what they have done along the way, and demonstrate their understandings and the process. By applying these stages to CAS, students have a reliable yet flexible structure they can then apply to future situations with confidence.
There are two parts as noted in the diagram. The centre represents the process with four key parts: investigation, preparation, action, and reflection (occurring intermittently in response to significant experiences). The outer circle has two parts and guides students in summarizing their experience: reflection and demonstration.
The five CAS stages are as follows.
Investigation: Students identify their interests, skills and talents to be used in considering opportunities for CAS experiences, as well as areas for personal growth and development. Students investigate what they want to do and determine the purpose for their CAS experience. In the case of service, students identify a need they want to address.
Preparation: Students clarify roles and responsibilities, develop a plan of actions to be taken, identify specified resources and timelines, and acquire any skills as needed to engage in the CAS experience.
Action: Students implement their idea or plan. This often requires decision-making and problem-solving. Students may work individually, with partners, or in groups.
Reflection: Students describe what happened, express feelings, generate ideas, and raise questions. Reflection can occur at any time during CAS to further understanding, to assist with revising plans, to learn from the experience, and to make explicit connections between their growth, accomplishments, and the learning outcomes for personal awareness. Reflection may lead to new action.
Demonstration: Students make explicit what and how they learned and what they have accomplished, for example, by sharing their CAS experience through their CAS portfolio or with others in an informal or formal manner. Through demonstration and communication, students solidify their understanding and evoke response from others.
The CAS stages provide a framework that enables students to:
increase self-awareness
learn about learning
explore new and unfamiliar challenges
employ different learning styles
develop their ability to communicate and collaborate with others
experience and recognize personal development
develop attributes of the IB learner profile.
For singular CAS experiences, students may begin with investigation, preparation, or action. For ongoing CAS experiences, beginning with investigation is advised. In these ongoing experiences, the action stage may lead students back to investigation or preparation as they further develop, expand and implement new or related ideas.
The CAS coordinator ensures that CAS advisers and other supporting staff, as well as CAS students, understand the CAS stages so they are readily applied to advance the students’ CAS programme.
