Evidence-based assessments and interventions for nurseries and primary schools

From the creators of the Nuffield Early Language Intervention (NELI). Based on extensive University of Oxford research into children’s educational development and used by over 10,000 schools.

Proven to improve educational outcomes for the children who need most help.

National roll-out of Nuffield Early Language Intervention (NELI) boosted young children’s language skills by four months


A new independent evaluation of NELI found that children who took part in the programme made on average four months’ additional progress in their language skills. It also found that children eligible for Free School Meals (FSM) made on average seven months’ additional progress as a result of receiving the programme, suggesting that NELI could help to close the language development gap between socio-economically disadvantaged children and their peers.
