The programmes that RIVM manages on behalf of various government ministries are assessed annually by the commissioning parties. This assessment is conducted by means of a dialogue between the commissioners and RIVM. We sit down together to reflect on the programme, mapping out the positive and negative experiences over the past year. Using that overview as a starting point, we work together to improve our products and coordinate them more effectively. All the government bodies that have commissioned work from RIVM are satisfied with the execution of the programmes and have given RIVM an average mark of 8 out of 10.
