The CAS requirement is a fundamental part of the programme, and takes seriously the importance of life outside the academic world, providing a refreshing counterbalance to academic studies.  It is comprised of three parts:

• Creativity is interpreted broadly to include a wide range of arts activities as well as the creativity students demonstrate in designing and implementing service projects.
  
• Action can include not only participation in individual and team sports, but also taking part in expeditions and in local or international projects.  Action is about bettering one's physical self.
  
•  Service encompasses a host of community and social service activities. Some examples include helping children with special needs, visiting hospitals and working with refugees or homeless people.

Students are expected to be involved in CAS activities for the equivalent of at least three hours each week during the two years of the programme, for approximately 150 hours throughout their junior and senior years.

The CAS Coordinator for Lubbock High School is Jennifer Harris.  She is responsible for helping students find a varied choice of activities and guiding them in their completion of these activites.  It is ultimately the students' responisiblity, however, to create and/or find activities to work on. 

A system of self-evaluation encourages students to reflect on the benefits of CAS participation to themselves and to others, and to evaluate the understanding and insights acquired.  Logs and reflections must be submitted to Mrs. Harris by the dates assigned.  Additionally, students will complete a minimum of two individual interviews with Mrs. Harris to reflect upon their CAS experience.  Completion of CAS is mandatory to receive one's IB diploma.

Programmes are monitored by IB regional offices.
