if the training is considered part pf the 5 years work experience
Classroom preparation for module examinations on a so-called course cannot be considered as valid work experience!
5 years work experience CAN be combined with preparing for and taking the Module examinations, and many people do this. But the work experience must be full-time and relevant, so the study and exams must be in the student's own time.
The only things that need to be paid for are the home study material, possibly some short intensive courses for each Module (ie a week or two at most) and the Examination fees.
