Abstract: This study examines the social representation of students from two engineering schools at the Institut National Polytechnique Felix Houphouet Boigny (INP-HB) according to their future occupations. It contributes to the general literature of social representation by focusing on the quantitative method of paired comparison. The investigation was carried out by establishing a scale of preference for nine statements expressing various professional activities performed by engineers. A group of students from two engineering schools (College of Industry (ESI) and College of Commerce and Business Management (ESCAE)) participated in this research. Results have shown that the application of the method of paired comparisons in the hypothesis of three by Thustone makes the discriminative variance process remains constant whatever the pairs considered. The calculation of scores is made from the conversion of frequency into standard deviation. This conversion has allowed us to obtain the matrix of standard deviation for each school. The average of standard deviation for each item column is calculated to obtain the average score for the items considered. According to the items selected, students have divergent choices depending on their membership to a particular school. Thus, knowledge produced by the analysis of representation is not only a mere analysis of speech or interpersonal exchanges, but it constitutes an invaluable means for the understanding of the basic system of thought and personal or collective actions of the students.
