The better one is http://www.iea.sg. Site of the Institute of
Estate Agents. There you see Continuing Professional Development
activities, CPD Core, and CPD Non Core. Think no exam but you need
to clock hours for renewing your licence.
If I am not wrong, Financial Advisers( Insurance Agent), Medical
and Dental Doctors as well as some other professionals have similar
requirements to renew their professional licence.
