The aim of this study was to measure the level of social responsibility among students of the general diploma in the schools of AL Dakhiliyah Governorate in Sultanate of Oman and recognize the relationship between social responsibility and motivation of achievement in light of some variables (gender, birth order, and family income level). To achieve the aim of the study, the researcher used two measures; the first measure is the social responsibility, which consists of (40) paragraphs divided into five dimensions: (personal self-responsibility, moral religious responsibility, social responsibility and national responsibility). The second measure is the measure of achievement motivation which consists of (36) paragraphs divided into five dimensions: (goal setting and its clarity, ambition, perseverance and perceived efficiency). Their validity and steadfastness have been verified. A random sample was selected from the study population represented by the general diploma students in AL Dakhiliyah Governorate in Sultanate of Oman, 5452 male and female students enrolled in the academic year 2016- 2017. The sample consisted of (825) male and female students i.e. (15%) of the size of the study population. The results of the study concluded in the following: •The level of achievement motivation and level of social responsibility was high in the study sample. • There were statistically significant differences at the level of significance (a≤0.05) in the estimations of the study sample on the level of achievement motivation and the level of social responsibility attributed to gender variable in favor of females. There were no statistically significant differences at the level of significance (0.05=a) in the estimations of the study sample on the• level of achievement motivation and the level of social responsibility attributed to the variable of birth order. There were no statistically significant differences at the level of significance (0.05-a) in the estimations of the study sample on the• level of motivation achievement attributed to the variable of family income level.
