CAM
Several Certificate of Advanced Mastery courses are available at Century, including Health Services, Digital Technology, PAC, Business, and FAME. Students choose their CAM in their junior year and start taking the prerequisites for the classes. The CAM classes give students time to work on their senior project, which must be completed before they can graduate.
CIM
The CIM is an acknowledgment that a student has met rigorous standards by acquiring skills in several academic areas. Both CIM and CAM requirements are being phased out of the Hillsboro School District.
