Nuffield Early Language Intervention

This page covers the first (efficacy) trial of Nuffield Early Language Intervention, which tested whether it could work in schools under best possible conditions. To read about the second (effectiveness) trial - testing a scalable model under everyday conditions in a large number of schools - click here.

The Nuffield Early Language Intervention (NELI) is designed to improve listening, narrative and vocabulary skills. Three to five weekly sessions are delivered to small groups of children with relatively poor spoken language skills. The 30-week programme starts in the final term of nursery and continues in reception year. The 20-week programme is delivered in reception only.

EEF Summary

The attainment gap between disadvantaged children and their more affluent peers opens early and continues throughout schooling. There is a wealth of evidence to show that early intervention has great potential to narrow the gap, but few nursery and reception year programmes have been rigorously tested for impact. This is why the EEF funded the Nuffield Early Language Intervention.

Children receiving the 30-week version (beginning in Nursery, and continuing in early Reception) made about four months of additional progress in language skills compared to children receiving standard provision. The impact of the 20-week version (delivered solely in Reception) was smaller. These impacts on language skills were still seen 6 months after the intervention.

On average, children with better language skills also have better literacy skills, so it might be expected that by improving language skills we can also improve literacy. However, this evaluation provided no reliable evidence that the programme had a positive impact on children’s word-level literacy skills in the short term.

The EEF is funding a further trial of NELI to find out if the results can be replicated when the programme is delivered to a larger number of schools. This will also allow follow up of longer term outcomes.

Were the schools in the trial similar to my school?

Across the schools involved in the trial, 26% of pupils were eligible for free school meals. One percent had special educational needs, and 11% had English as an additional language. 

Could I implement this in my school?

 The EEF is testing this scalable approach that could be made available to schools across the country.

The Nursery element, and the 30 week version, are not currently available to buy.

How much will it cost?

The programme is relatively cheap to buy but requires significant delivery time from TAs. The cost of the training and materials for one TA to deliver the 30-week intervention in the evaluation was just under £2,500. The TA could then deliver the intervention repeatedly. In terms of staff time, for the 30-week intervention there is a total requirement of 110 hours per group of four children.

The commercial cost of a resource pack and training for the available 20 week programme is £1,040 and is available from Oxford University Press.

Evaluation Conclusions

  1. The Nuffield Early Language Intervention had a positive impact on the language skills of children in the trial. This is true for both the more expensive, 30-week version, starting in nursery, and the 20-week version, delivered only in school.

  2. Children receiving the 30-week version experienced the equivalent of about four months of additional progress, compared with about 2 months additional progress for the 20-week version. Both results are unlikely to have occurred by chance, though results for the 30-week version are more secure.

  3. The evaluation did not provide reliable evidence that either version of the programme had a positive impact on children’s word-level literacy skills.

  4. Teaching assistants delivering the programme reported that they found it difficult to devote enough time to it, and that support from senior staff was required to protect the programme time.

  5. Staff in participating schools reported that the programme had a positive impact on children’s language skills and confidence. They thought that the factors which contributed to this included the small-group format, the activities covered, and the focus on narrative and vocabulary work.
