UWI students from St Augustine pay per credit.  Those students wishing to do so should request on-campus accommodation when applying to CLLI.  UWI students from Cave Hill and Mona pay for tuition (depending on the number of courses read for credit), accommodation and most meals.  International students pay for tuition, accommodation and meals. 

UWI students who are sponsored by the governments of contributing CARICOM territories pay per course (for credit), but may also audit courses for their interest.  International students (from non-contributing CARICOM or other territories) can pay for courses for credit or for auditing.
