An Intervention is a piece of work you need to do in order to achieve your chosen outcome. You will need to select two different interventions, one for the Whole School Outcome and one for the Children in Challenging Circumstances Outcome.
To get an idea of good quality interventions, have a look at the Intervention Directory. The interventions suggested are all evaluated or are based on NICE good practice guidelines and so can be relied on to make a positive difference if implemented correctly.
The choice of interventions is deliberately small. This is to ensure that the work is reliable and that schools will be successful.
Some interventions may incur a cost to the school.
