Predicting curriculum and test performance at age 11 years from pupil background, baseline skills and phonological awareness at age 5 years

Background: Phonological awareness tests are amongst the best predictors of literacy and predict outcomes of Key Stage 1 assessment of the National Curriculum in England at age 7. However, it is unknown whether their ability to predict National Curricular outcomes extends to Key Stage 2 assessments given at age 11, or also whether the predictive power of such tests is independent of letter-knowledge. We explored the unique predictive validity of phonological awareness and early literacy measures, and other pupil background measures taken at age 5 in the prediction of English, Maths, and Science performance at age 11. Method: Three hundred and eighty-two children from 21 primary schools in one Local Educational Authority were assessed at age 5 and followed to age 11 (Key Stage 2 assessment). Teaching assistants (TAs) administered phonological awareness tasks and early literacy measures. Baseline and Key Stage 2 performance measures were collected by teachers. Results: Phonological awareness was a significant unique predictor of all nine outcome measures after baseline assessment and pupil background measures were first controlled in regression analyses, and continued to be a significant predictor of reading, maths, and science performance, and teacher assessments after early literacy skill and letter-knowledge was controlled. Gender predicted performance in writing, the English test, and English teacher assessment, with girls outperforming boys. Conclusions: Phonological awareness is a unique predictor of general curricular attainment independent of pupil background, early reading ability and letter-knowledge. Practically, screening of phonological awareness and basic reading skills by school staff in year 1 significantly enhances the capacity of schools to predict curricular outcomes in year 6.
