Despite the growing international focus on neurodiversity, its explicit identification and incorporation into educational and workplace practices remain underdeveloped in Saudi Arabia. This study explores the indirect presence and characterisation of neurodiversity within Saudi Arabia through existing inclusive practices. The study aimed to analyse the prevalence and characteristics of neurodiversity practices in Saudi Arabia, using inclusive education, mainstreaming education, inclusive society, and inclusive work as indicators, and to develop a conceptual model for neurodiversity applicable both locally and globally. A content analysis was conducted on 33 studies related to inclusive practices in Saudi Arabia. Data were categorised into emergent themes to construct a conceptual model that encapsulates neurodiversity practices. The findings revealed eight categories representing neurodiversity practices: Teacher Preparedness and Training, Policy and Implementation, Inclusive Educational Practices, Assistive Technologies and Resources, Socio-emotional and Health Support, Specialised Training and Professional Development, Student and Peer Perspectives, and Inclusive Infrastructure. The proposed conceptual model synthesises these categories, providing a structured depiction of neurodiversity practices in Saudi Arabia and offering a framework with international applicability. This study uncovers an implicit acknowledgment of neurodiversity and a foundational approach to inclusive practices within the Saudi Arabian context, parallel to global inclusive trends.
