Why is there no central clearing house for these types of professions.
We all have to go through CRB, should there not be the same professional checks for FC, Engineers and CC. Once you have passed your exams and been certified, then you get put on the list by the accrediting body. At the time of taking a new post, then a certificate is required from the clearing house in the same manner.
If there is then I stand corrected, if there is not then why not.
