Potters Bar Clinic School opened on July 1 in its current premises at the clinic on Barnet Road, where its current pupils are inpatients.
The independent special school is owned by private mental healthcare provider Elysium Healthcare, which also owns Potters Bar Clinic and Rhodes Hospital School in Hatfield.
The majority of the pupils, aged between 11 and 19, have social, emotional and mental health needs. They have been using the hospital ward breakout areas as their classrooms, but by September 1 they will have their classes in purpose-built accommodation on the second floor of the clinic.
An Ofsted pre-inspection published in June stated that the school is likely to meet the requirements for all standards it measures, including quality of education, safety, social development, transparency, premises, and leadership.
The mixed-gender school, which will exclusively serve children with SEN, can accommodate 30 pupils and will have seven full-time and four part-time teaching staff.
At least some of these teachers will be brought over from Rhodes Wood, and pupils will also be supervised and supported, sometimes over 24 hours, by key workers employed by the clinic.
