The Zones of Regulation is a range of activities to help a student develop skills in the area of self-regulation. The various ways students feel and the states of alertness they experience are categorized into four coloured zones: Red, Yellow, Green, and Blue. Well-regulated students are able to be in the appropriate zone at the appropriate time. The aim is to have all students in the green zone throughout the day.
