It was found that social class of origin predicts educational attainment in both the participant's and offspring generations. Father's social class and participant's social class held the same importance in predicting offspring educational attainment—effect across two generations. Educational attainment mediated the association of social class attainments across generations (father's and participants social class, participant's and offspring's social class). There was no direct link between social classes across generations, but in each generation educational attainment was a predictor of social class, which is consistent with other studies. Also, participant's childhood ability moderately predicted their educational and social class attainment (.31 and .38). Participant's educational attainment was strongly linked with the odds of moving downward or upward on the social class ladder. For each SD increase in education, the odds of moving upward on the social class spectrum were 2.58 times greater (the downward ones were .26 times greater). Offspring's educational attainment was also strongly linked with the odds of moving upward or downward on the social class ladder. For each SD increase in education, the odds of moving upward were 3.54 times greater (the downward ones were .40 times greater). In conclusion, education is very important, because it is the fundamental mechanism functioning both to hold individuals in their social class of origin and to make it possible for their movement upward or downward on the social class ladder.
