The evaluation by the Education and Training Inspectorate of the Science, Technology, Engineering and Mathematics (STEM) Careers Education, Information, Advice and Guidance (CEIAG) Programme was undertaken to inform the Department and the Education and Library Board Strategic and Operational STEM CEIAG groups of the effectiveness of the programme. The findings also have important implications for Departmental policy and strategy to support the effective delivery of support for STEM in schools in the future.
