The Forest School process has 6 principles, created, and agreed upon by the Forest School community.
These are:

1. Forest School is a long-term process of frequent and regular sessions in a woodland or natural environment, rather than a one-off visit. Planning, adaptation, observations, and reviewing are integral elements of Forest School.
2. Forest School takes place in a woodland or natural wooded environment to support the development of a relationship between the learner and the natural world.
3. Forest School aims to promote the holistic development of all those involved, fostering resilient, confident, independent, and creative learners.
4. Forest School offers learners the opportunity to take supported risks appropriate to the environment and to themselves.
5. Forest School is run by qualified Forest School practitioners who continuously maintain and develop their professional practice.
6. Forest School uses a range of learner-centred processes to create a community for development and learning.
