This paper will introduce a model of in-service professional development applied in the Israeli Education system: The Pedagogical Flexibility in Teachers’ Professional Development. This model has been applied and administered in Israeli schools by school principals recently. In addition, this paper will illuminate the two state reforms operating in the Israeli education system, which constitute one of the contexts in which principals work. It will be argued that among the plethora tasks school principals are in charge of, this task is less prioritised.
