Relevant experience is often more highly valued than secretarial qualifications, although excellent IT and typing skills will always be an essential requirement.
Temporary work can often lead to permanent positions and, if you do not have much previous experience, a temporary or part-time job will provide an opportunity to try different types of secretarial or administrative work. This can help you to decide which aspects of this work you particularly enjoy and what sort of employer or sector you would like to work with.
