The aim of the current research was to theoretically analyze the Rothwell’s model for succession planning and to clarify its sequential steps for the preparation of the alternative leader, as well as to theoretically analyze the job description card (form) for the school principal in the Egyptian Ministry of Education, in order to come up with some suggestions for the preparation of the second-line leadership at school or the alternative leader in a model scientific manner that is proven successful. To achieve the aim of this research, the descriptive research method was adopted in order to describe and clarify the studies related to the two variables of the present research, in addition to attempting to come up with theoretical generalizations that can be used. This research concluded with a proposal to plan the succession of the school principal in light of the Rothwell’s model, which consists of seven steps, each step includes a set of executive procedures that take place inside the school and through which succession planning can be achieved for the school principal.
