Depending on the positions involved, candidates may enter directly from school, or on completion of a third level qualification from college or university.
Usually, applicants may be of any age provided they meet the eligibility criteria listed in the job advert.
There is no limitation on the types of courses acceptable except in the case of professional and technical positions where appropriate qualifications/experience is required.
