Students attend secondary school for a minimum of five years, leading to the CSEC (Caribbean Secondary Education Certificate) examinations, which is the equivalent of the British GCSE O levels. Children with satisfactory grades may opt to continue high school for a further two-year period, leading to the Caribbean Advanced Proficiency Examinations (CAPE), the equivalent of GCE A levels. Both CSEC and CAPE examinations are held by the Caribbean Examinations Council (CXC). Public Primary and Secondary education is free for all, although private and religious schooling is available for a fee.
