Special Episode - The National Literacy Trust Independent Evaluation of Lexonik Advance - the results are in!

Our latest Vocabulary Detectives podcast episode centres on the news that the National Literacy Trust has completed its 12 month assessment of our Lexonik Advance intervention.

Sarah and Lisa discuss the outstanding conclusions of the NLT impact evaluation, and delve into the issue of why an educational provider might seek to get its product or service externally assessed.

Not only was the NLT able to conclude that Lexonik Advance had had significant impact on students – in terms of reading age gains and literacy confidence – but, significantly, that there was positive and marked impact on the teachers being trained.

Summary findings in the report include:

  • The median increase in reading age for participating students was 24 months over a 2.2-month period
  • On average, standardised scores increased by 7.8 for those aged 11 to 12, by 11.5 for those aged 12 to 13, and by 15.4 for those aged 13 to 14
  • The programme was particularly beneficial for students who began with decoding skills below the national average
  • Score changes were sustained long after the programme ended
  • Over 3 in 4 teachers (77.4%) felt that participating students made more progress than their peers
  • More than 1 in 2 (54.7%) had noticed a change in students’ overall confidence
  • More than 2 in 5 (44.2%) felt students’ independence had improved
  • Staff members also benefited from the programme in terms of their own practice and confidence supporting students’ reading
  • 9 in 10 (90.2%) felt that the programme increased their confidence to support struggling readers effectively
  • Nearly 9 in 10 (89.0%) thought the programme was valuable for their professional development
  • More than 9 in 10 felt that they had a better understanding of how to support students’ vocabulary development
