The Net Effect of Mother’s Qualification:
Reading
In terms of parents’ highest social class of occupation (family SES), compared with ‘professional
non-manual’, all other categories were associated with lower attainment levels for both Reading
and Mathematics. Statistically significant lower attainment was found for children whose parents
belong to the groups ‘skilled non-manual’, ‘skilled manual’ and ‘semi-skilled’ in Mathematics. In
Reading the category ‘unskilled’ was associated with significant lower attainment in addition to
the categories reported for Mathematics. Results in terms of effect sizes are illustrated in Figure
1.5 for Mathematics. Effect sizes can be quantified as small to moderate in the range between
0.11 and 0.36 for Reading outcomes and between 0.16 and 0.31 for attainment in Mathematics.
