Independent Impact Evaluation Studies
At Lexonik we are always eager to test the validity of our intervention programmes. That is why we commission Impact Evaluation Studies to make sure our literacy programmes are verified. You can see for yourself by downloading the studies below.
National Literacy Trust Study
This report presents the findings of this evaluation, focusing on changes in students’ reading attainment alongside changes in school staff’s teaching and classroom practice. Student data was collected using a decoding subtest of a standardised test called Wide Range Achievement Test (WRAT5), which provided standardised scores and reading age on students’ decoding before and after taking part in the programme.
Northumbria University Study
All data scrutinised was collected during the Spring, Summer and Autumn Terms of 2014. Student data, from a range of schools, was analysed to look for trends and patterns according to their year group and chronological age.
The average gain across all cohorts, as measured by reading age, was 27 months.
