Kemball admits students with a wide range of special needs. These vary from profound and complex, to moderate learning difficulties. Many students have additional complications including medical and physical needs, some of them life limiting. There has been a recent influx of students with moderate learning difficulties, often with additional emotional problems. Students can join the school at any age; those with profound and severe difficulties often join when they are very young but those with more moderate learning difficulties often join the school in Years 5, 6 and 7. About a half of students are known to be eligible for pupil premium funding (extra money provided to schools by the government for students being looked after and those known to be eligible for free school meals); this is well above the national average. There are about twice as many boys as girls; most students are of White British heritage. A new deputy headteacher has been appointed since the last inspection and there are some new teachers. The school provides guidance for many mainstream schools to help their staff develop the skills they need to meet the needs of children with learning difficulties. The school is due to move in September 2013, to newly built premises on the same site as a secondary academy school.
