Direct And Indirect Effects Of Social Class On Career Expectations And Likelihood Of Compromise In An Adolescent Sample, Sarah Wilson

Dissertations

The current study investigated the application of classic attainment models, both direct and indirect effects, in the predication of career expectations and likelihood of compromise. The results indicated that among high school students (N=200) in grades 10-12 there is no direct effect of socio economic status (SES; as measured by parent education and occupation) on career compromise (aspirations exceeding expectations). Similarly, educational expectations are not directly related to the compromise of occupational expectations. Results of exploratory analysis suggest that career compromise is best explained by academic achievement and parent expectations. In an analysis of the process by which social class …
