Examining local level variation in Special Educational Needs and Disabilities (SEND) service provision and associated data sources in England: a scoping review.

The Special Educational Needs and Disabilities (SEND) system in England was reformed in 2014, including the introduction of child-centred legally binding education, health and care plans (EHCPs) and expectations for improved multi-agency working coordinated by local authorities (LAs). Since then, service-user satisfaction has declined, and children's outcomes have not improved. Critics cite local variation in SEND provision and limited accountability for implementation failures as contributing factors. This scoping review summarises peer-reviewed and grey literature as well as open-access data sources reporting LA and multi-academy trust (MAT) level variation in SEND provision to identify key reasons for local variation SEND services, and data sources that could be used to better monitor local public bodies. We identified and graded 120 articles/reports (18 peer-reviewed, 102 grey) and 8 open-access data sources. The literature investigated nine topic areas; most studies were low quality. Eight open-access data sources included information about SEND prevalence, demand and provision complaints. Our review highlights that LAs were underprepared and under-resourced to implement the reforms. The administration involved in EHCPs contribute to variation in multiple ways. Greater standardisation and guidance for professionals could reduce variation. Existing data sources could be better used to improve monitoring and accountability for local provision, which should include MATs given their potential to influence SEND provision. Low-quality studies dominated the grey literature. More rigorous methods and reporting standards could also improve decision-making and service planning.
