Fortuna School caters for pupils who have behavioural, emotional and social difficulties. Many have additional needs, such as attention deficit hyperactivity disorder (ADHD). All pupils have a statement of special educational needs or an education, health and care plan. Most pupils are White British and few pupils speak English as an additional language. There are approximately five times more boys than girls. A high proportion of pupils, approximately two thirds, are eligible for pupil premium funding. This is additional funding for pupils known to be eligible for free school meals and those in care of the local authority. Although the school is designated for pupils aged from four years old, the youngest pupils attending the school during the inspection were in Year 1. This is similar to the time of the previous inspection when the youngest pupils attending were in Year 2. Most pupils start at different times during the first half of the autumn term each year, although 21 new pupils arrived together at the beginning of September 2014. Most pupils have experienced previous disruption to their education and a significant number, nearly one third, have been excluded from their previous schools. Since the last inspection, the nature and severity of pupils’ needs has increased. For example, there has been almost a five-fold increase in the number of pupils referred to the school who are in local authority care.
