One of the ultimate goals in improving students’ quality of life is to provide them with quality learning experiences in schools. This goal has led many developed and developing countries to establish educational policies that encourage school practitioners to implement systems and practices that maximize students’ positive outcomes in both special education and inclusive school settings. Policy initiatives have influenced schoolwide practices and processes in many ways to change the requirements of schools and implement new approaches. Schools are directed by policies and then either strengthen or hinder implementation. Translating policies into practices can be sometimes complex and difficult. Many schools are faced with implementation failure due to a variety of factors, ranging from teacher problems with confidence, skills, and knowledge or issues in adapting to the changed practices of larger systems. Meeting these challenges requires the involvement of teachers, schools, stakeholders, and policymakers to close the gaps between existent policies and actual school practices. One promising approach to closing the gaps is known as implementation science, which is centered on a systematic process to promote the adaptation of research-based practices and other evidence-based policies into a regular routine. Core components include ongoing coaching, staff selection and training, and support systems. These components need to be employed and sustained at a high level for successful implementation. To achieve better outcomes, schools and all stakeholders require a systematic process of transferring policies. Stages of implementation considered as a formal protocol include exploration, installation, initial implementation, full implantation, innovation, and sustainability. Community-wide efforts are required to improve the uptake and effectiveness of policies in school contexts.
