Nurseries wishing to participate were invited to training sessions in their regions. These sessions aim at contributing to a better understanding of the indoor environment quality and at providing with training in self-assessment. Voluntary nurseries then received the questionnaire and the explanatory guidelines by mail (creches2).
The participating nurseries had to observe their indoor environment and had to answer the questions within two weeks’ time. The project managers provided for the necessary support (help desk).
Some nurseries were asked to take part, on a voluntary basis, in this second phase of the project, during which the SAMI has visited them.
