What is it about?
To investigate the relationship between language knowledge at 5 years of age and later academic achievement throughout 10 years of compulsory school in Iceland

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
