The rationale underpinning the inclusion on or omission from the lists of any particular occupation is driven by skills demands in the economy, and is based on, in the first instance, the research and labour market intelligence undertaken by the Skills and Labour Market Research Unit (Solas), the Expert Group of Future Skills Needs, the National Skills Council, education outputs, sectoral upskilling and training initiatives and any known contextual factors (e.g., planned expansions in sectors, if known). The observations and input of relevant Government Departments are also incorporated in addition to the public consultation process. Submissions to the review process are also considered by the Economic Migration Policy Interdepartmental Group chaired by the Department of Business, Enterprise and Innovation with membership drawn from senior officials of key Government Departments and Solas.
