No, I’d prefer practical experience over all the certificates in the world. Most anyone can sit and pass a test, but the real world demands much more. I’d take certificates with a grain of salt. If it was between someone who had experience and someone who had just a certificate but little or no experience, Experience would win hands down. Certificates can alway be acquired if needed, but experience is $$$ you are spending training or teaching once hired. The certificate has not done anything other than prove that they can learn and retain, but haven’t put into practical use nor exhibitied the other traits needed (Dealing with users, customers, other staff, how they handle problems, sress, etc.).
