No, a CSK assessment must be conducted every three years or as per expiry date.
CSK is an on-going process as the test is a condition of registration or licencing for certain client types. Post the initial Reregistration project, new Registrants/ Licensees would have to complete the test prior to applying to be registered/ licenced. Also existing registrants/ licensees will have to rewrite the test as CSK qualification is only valid for 3 years.
