Chief Scientific Advisers

Most government departments have a Chief Scientific Adviser (CSA) to provide scientific advice.

Departmental CSAs work together under the leadership of the Government Chief Scientific Adviser to support each other and to resolve cross departmental problems.

They do this primarily through the CSA network.


The network advise the Government Chief Scientific Adviser on all aspects of policy on science and technology. In particular, they:

  • provide advice to ministers, through the Cabinet committee system
  • discuss and facilitate implementation of policy on science, technology, engineering and mathematics (STEM)
  • identify and share good practice in STEM-related areas, including the use of scientific advice in policy making
  • facilitate communication on particular high profile STEM-related issues and those posing new challenges for government
