The purpose of the present investigation was to determine the extent to which social class, family system and family occupation determine the achievement motivation. For this 120 intermediate students were administered McClelland's Need Achievement Test. The results indicated that middle class socio-economic status, nuclear family system and entrepreneurial occupations are associated with high achievement motivation while upper and lower class socio-economic status, joint family system and bureaucratic occupations are associated with low achievement motivation. The interaction effect of social class X family system was only significant. Other interactions were not significant.
