Forest School is a long term developmental programme that takes place on a regular basis, typically once a week, for a minimum of 6 sessions, but usually longer. To lead a Forest School programme it is necessary to be a Level 3 certificated and qualified Forest School practitioner, and hold a current and appropriate Outdoor First Aid qualification.

Forest School takes place in a range of situations across the UK. In Scotland and Wales it is part of the broader aims of Outdoor & Woodland Learning Scotland (previously known as the Forest Education Initiative or FEI).
