A certificate is a qualification comprising 10 to 29 credits. All certificates have similar size or duration but may vary in the complexity of their content. Complexity of the content of the certificate is indicated by the CXC-QS level, for example, Level 1 through to Level 6. A Level 6 Certificate is also called a post-graduate certificate while a Level 1 certificate is a (10-29 credit) qualification which prepares the learner to use knowledge, skills and understanding to carry out simple tasks and activities with support. Certificates usually have wider theoretical bases than awards. The CXC-QS describes typical educational and occupational levels and what the certificate holders should be able to do at each level.
