This study presents data collected towards the end of their school car
eers from pupils originally studied at pre-school age as part of the B
ristol Language Development Study. Data were originally collected on v
arious aspects of the early language development of these children and
, in particular, on naturally occurring language in the home, based on
recorded samples of verbal interactions. More recently, data have bee
n collected on the 16+ examination performance of these children as th
ey reach the end of compulsory schooling. The analysis demonstrates a
considerable degree of continuity between early language development a
nd later examination performance, and also a strong relationship betwe
en family background and examination results and a moderate relationsh
ip between family background and early language measures. Further anal
ysis provided some support to a model which accounts for the relations
hip across time in terms of the influence of social background on both
early and later measures. A model which has early language as a key f
actor in explaining the relationship between family background and exa
mination results received little support from the data.
