In Saudi Arabia, it is generally perceived that private special education institutes (SEIs) provide a higher quality education than their public counterparts. Parents tend to trust and invest in private rather than public institutes. This is principally attributed to the greater financial capacity of private special institutes, which ensures services can be provided more effectively. Investigating this perspective, this study seeks to bridge the gap often observed and commented upon between public and private SEIs, and to reflect critically on how the needs of all students with intellectual disabilities can be met within the public system. A comparative case study of two SEIs in Saudi Arabia for students with intellectual disabilities, one public and one private, was designed. Semi-structured interviews were conducted with parents, teachers and principals. A key finding of this study is that there is a major difference in the workplace cultures of public and private institutes. This results in several observable factors that were found to contribute to the quality of provision for learners.
