Why is it important?

The study showed strong correlation between phonological awareness at 5 years and academic achievement in Grades 4, 7 and 10. There was also a significant but lower correlation with oral comprehension skills. Regression analysis showed that the preschool oral language assessments in phonological awareness and oral comprehension explained between 35% and 43% of the variability in scores on national tests in Icelandic and between 20% and 39% of the variability in scores in mathematics


Preschool language knowledge is a reliable predictor of later academic achievement. It is very important to improve and assist children to master the language at school
