Hi a warm welcome to the site. Holistic plans are ones that take the whole child into consideration, not just single areas of learning and development.
Ask in your setting/workplace/placement to see how they plan for all the child to have access to the outside play areas eg. through a continuous planning approach, a daily routine, free-flow approach. Is the planning adapted so that children with specific needs go outside eg. aids to make sure children can take part - ramps, low level door handles, staff ratios
The
level 3 early years educator handbook - on amazon.co.uk has good reading if you use the index and look for 'holistic'
