In the 2009/10 school year, the Department of Health together with the Education Bureau launched the EatSmart School Accreditation Scheme (ESAS) under the "EatSmart@school.hk" Campaign (ESS Campaign), with the aim of motivating and helping all primary schools in Hong Kong to formulate and implement healthy eating school policy, build up a learning environment conducive to healthy eating, and cultivate and strengthen a good eating habit among schoolchildren.

The ESAS encourages family, school and the community to work together in formulating specific objectives in stages, so that the school will ultimately become an ideal EatSmart School.
