The research used a descriptive-analytical method and a sample of (350) female field teachers to examine the effects of preschool education on the administrative and educational competencies of students in Oman's first cycle of basic education. The research came to the following conclusions: Students who entered preschool education had a high arithmetic average of (3.93) for administrative competencies, and their educational competencies were also rated highly as the arithmetic average reached a high level (3.85). Administrative skills were ranked in the following manner for the first axis: (Planning, Communication, Organization, and Leadership). In terms of the second axis, which is concerned with educational skills, the study's results for reading, listening, and writing all fell within a high degree (3.67-4.09) of the arithmetic mean. This result is consistent with many international studies and trends in all countries, which concurred on the significance of the preschool education stage. Despite its significance, the research indicated that this stage is still optional in the Sultanate of Oman. The research suggests that the Ministry of Education makes preschool education mandatory by supplying and utilizing all the resources. [For the full proceedings, see ED654100.]
