NELI is best delivered by the same member of staff to ensure a consistent approach to the intervention. If the staff providing the programme to pupils is absent for a prolonged time, please feel free to extend the number of delivery weeks to run the programme for longer through the summer term. When you restart after a prolonged break, revise the sessions of the topic already covered and then move forward to the new sessions for that topic.
If the likely absence length means the 20-week programme no longer fits into this academic year you can instead request for another member of staff to access the online training so they can deliver the programme to pupils in their place. Splitting the delivery of the intervention between staff is much better than not being able to deliver the intervention at all.
