Both developing and developed countries allocate a substantial amount of their budgets to their education sectors in an attempt to improve the learning performance of the students at each stage in the education system. The stages in the education system are typically conceived as being: Early Childhood (EC), Elementary to Secondary School (K-12), and Post Secondary Education (PSE). Each of these stages requires attention to address its unique problems, particularly when each stage is viewed as a separate, isolated component. This paper presents a modeling framework that integrates the stages of the education system into a one complete system to evaluate the implications of success in one stage to other stages. This paper illustrates that in designing effective and robust strategies to improve learning performance, it is necessary to fully understand how the problems of one stage evolve over time and if not fixed, could generate or intensify the problems in other stages. This research helps in understanding “where and why” to focus education system reform efforts in order to improve the performance of the students throughout all stages of the education system.
