After children experienced the "Introductory Level" of Kids' ISO 14000 Programme, 80 % of them are stimulated and start to challenge "Primary Level"

In "Primary Level", children learn and make practice the methodology of envrionmental management. The target is "House hold", which is familier since they have already experience in the Introductory level. In the Primary Level, children turn the PDCA cycle (Plan - Do - Check and - Act Cycle) for 3 times, and also the child, as the leader of this project, decides the role of the family members to work with this programme in the home.

It will take 8 weeks to finish the Primary Level and it may be hard work to continue for this period, however, the most of the children completes the work with the workbook. This comes from their previous experience with the Introductory Level.
