"SENbetweener" is not an official or standardized term in UK education policy or legislation, but it is an informal description used by educators, parents, and advocates. It combines "SEN" (Special Educational Needs) and "inbetweener", referring to learners who fall between the boundaries of being formally identified as having SEN and being considered as having typical learning needs.
These students often face challenges that go beyond what can be addressed by standard classroom differentiation, but do not meet the threshold for formal SEN recognition or support plans (such as an Education, Health and Care Plan, or EHCP). They may struggle academically, socially, or emotionally, but their difficulties may be less severe, less clearly defined, or temporary, meaning they are sometimes overlooked or do not qualify for additional resources, leading to concerns that they "fall through the cracks" in the education system.
