A. To be able to quit studying B. To be in compliance with regulatory guidelines C. To obtain certificates that indicate a level of prefessional competence D. To prove they know safety rules and regulations
I agree that proof of professional competence is essential ('C')l, but I think that 'D' should be added as well since there is no better way to demonstrate knowledge of essential rules and regulations than with a comprehensive examination. Thank You, Carlos Velez.
