Worcestershire has seen a "shocking" rise in the number of children with special educational needs and disabilities (SEND) being home-schooled, often "by default", and running the risk of falling "out of sight" of the education system.
From fewer than 50 in 2016, the number has risen to almost 300.
A further 88 children with education, health and care plans (EHCPs) were being home-schooled as of September 2024, according to Worcestershire County Council.
One campaigner said parents felt they had no choice but to pursue home schooling, because "the system is letting them down" over school places.
