Definition

Learning difficulties is a broad term used for different conditions that affect the normal learning ability of individuals (Burt, 2004, p. 786). Learning difficulties can be identified with Read Codes (primary care) and/or ICD-10 codes collated from previously validated code lists or were compiled in collaboration with clinicians (John et al, 2022).
