The present work was about the esteem of oneself and cleverness of communication of the agents of the public corporations of the city of Goma/DRC case of the DPI, ONC and FPI So, we resorted to a questionnaire as scale of Likert managed in a direct manner to a sample uncertain of 55 agents pulled by the systematic technique. To strip and to treat the data, we resorted in the software SPSS, version 18. After the survey, we got the following results: The first hypothesis stipulated that the agents of the public corporations would use a weak level of the communication cleverness (relational, of precision and summing up) at the time of their benefits. The found results clearly show that the hypothesis is varied, because, more of the half of the topics develop the cleverness of communication in a moderate manner. The results referring to the effects of the social and demographic variables as age, the sex, the level of survey, the seniority and the organization don't have can be decided in the present article. As for the second hypothesis, one expected what the esteem of oneself encourages the communication of the agents of the public corporations positively at the time of their benefits. The results to which we succeeded show with precision that the hypothesis is invalidated, because, the results advanced by agents reflect weak and non-meaningful interrelationships with the esteem of oneself. The communication is a very large survey field but the cleverness of communication is even more precise concepts. Some aspects are sometimes appreciated partially, what constitutes some points of reference marks concerning the cleverness of communication for the future research.
