This paper gives a short overview of the UK government's STEM agenda and then considers one aspect in depth--the STEM Advisory Forum. It explains how the Forum operates to draw together views from across the STEM community through online discussions and face-to-face events. Four examples are given of topics that have been dealt with by the Forum. Firstly the topic of engineering, enrichment and engagement is covered through samples of various events and discussions. A major issue covered is the number of young people taking A Level mathematics. The background to the issue is explained and how views expressed on the Forum might have had some influence upon the Government's advanced level target and may yet impact on admissions behaviour in universities. A third short example of impact on the number of university places for STEM subjects is given and the piece finishes with an example of impact at local level in schools. (Contains 4 figures.)
