This study aims to know the impact of informal groups on decision-making within educational institutions and contribute to providing a solution to this problem. Also, it attempts to clearly demonstrate the impact of informal groups on the decision-making process. This study relied on the use of a descriptive analytical approach. The researcher devoted part of the research to the applied or field study, in which the researcher used the questionnaire as a tool to collect information related to the research hypotheses, which were distributed to a group of educational institutions (general education), and then reached a set of results, the most prominent of which are:-:There is a clear impact of informal groups on the educational process within institutions, and this is evident from the data included in the study, as the data proved (the issue that informal groups affect the decision-making process within the educational institution) Also, the impact of informal groups on the decision-making process with regard to the functional aspect, which led to a negative impact on decision-making, in addition to the weak ability of some of those in charge of public education institutions to make decisions that would raise the efficiency of the institution as a result of the unofficial intervention of some groups of an unofficial nature, as well as the weak efficiency of some administrative leaders who manage some educational institutions... etc. The matter also confirms the validity of the hypotheses under study, which say that some educational institutions in Libya are unable to make some of their own decisions that serve the interests of the institution due to the influence of informal groups. Among the recommendations and suggestions that the researcher reached through the study and the data collection tool, the most prominent are:-: 1- Keep informal groups away from interfering in any official work and evaluating competencies and placing them in the appropriate place 2- Excluding those with influence and personal interests from influencing decision-making within educational institutions 3- Excluding people who do not have administrative or scientific competence from their leadership positions in order to raise the administrative and scientific level. Keywords: informal groups, decision making, educational institutions, social environment.
