In 2014, the Convention on the Rights of Persons with Disabilities has come into force so that it was thought to be important to summarize the recent trends and movements of the “special needs classroom (tentative)” initiatives by reviewing the recent research studies and literatures that contribute to the construction and promotion of the inclusive education system. The purpose of the current study was to create the basic material to prepare for the future educational legal reform in special needs education by gathering the findings of the studies and literatures on the“ special needs classroom (tentative)” initiatives. The results, which were discussed from the viewpoint of the inclusive education system construction and promotion, suggested that it was important to give valuable supports for all students, including students who have disabilities 1) to provide the best practices based on students’ educational needs by building effective“ special needs education teams” and promoting collaborations between regular education and special needs education, and 2) to introduce environmental adjustment, accommodations, and modifications for the purpose of managing inclusive classrooms.
