Using data from the National Child Development Study, the paper develops a
complex path model predicting the occupational grade achieved by 4,298 empl
oyed British males at age 33. Most British social mobility research has bee
n based in the 'class structurationist' tradition, and the paper begins by
comparing this with the 'status attainment' tradition, which is more common
in the USA. The class structurationist approach has rarely analysed the fa
ctors influencing individual occupational attainment, and those working in
this tradition in Britain have often assumed that people from working-class
origins fare worse on average than those from the middle class because of
factors associated with their class disadvantage rather than any difference
in individual characteristics such as ability or ambition. Status attainme
nt research, however, has generally found that individual ability and motiv
ation are the key factors influencing occupational attainment, and that cla
ss origins count for comparatively little. Using various measures of class
origins, parental support, qualifications, and individual ability and ambit
ion, the paper goes on to develop a linear structural equations model which
achieves a good fit to the data. The model demonstrates that individual ab
ility is by far the strongest influence on occupational achievement, that m
otivation is also important, and that factors like class background and par
ental support, while significant, are relatively much weaker. The paper con
cludes that occupational selection in Britain appears to take place largely
on meritocratic principles.
