An attempt to determine the relationship of SES to students' educ'al aspirations, & to demonstrate the degree to which this relationship is modified by each of 3 types of intervening variables: evaluation of educ, evaluation of self, & evaluation of society. Data were obtained from 5,632 M & F junior & senior HSch students' responses to a survey M. It was found that the relationship between SES & educ'al desires was strongly positive when the modified version of the Hollingshead 2-Factor Index of Soc Position was employed. Educ'al values were found to be independently related to SES & educ'al desires, & to be cumulative in effect. It was also found that each measure of self-evaluation used affected the original relationship between SES & desire for a Coll educ. The effect, however, is greater the lower the SE group. The effect of students' evaluation of society was pronounced for all classes. Among Uc students with positive evaluations, 83% desired Coll educ's as compared to 66% of those with negative evaluations. %'s for Lc students are 53.5% & 32.9%, respectively. The theoretical & action implications of these findings indicate that SC is basically a demographic variable with little explanatory power in & of itself. Only as we learn why & how SC diff's produce variations in goals, values & behavior can we understand the meaning of poverty or affluence. E. Weiman.
