A Merseyside head teacher has denied breaching health and safety laws after a student in his care fell through a school roof skylight.
John Summerfield, head of Sacred Heart Catholic College in Crosby, is alleged to have taken a group on to the roof when the 18-year-old fell 8ft (2.5m).
He suffered a fractured skull, broken ribs, permanent eye damage and a perforated eardrum.
Mr Summerfield pleaded not guilty at Liverpool Crown Court.
He is charged with breaching the Health and Safety at Work Act by failing to take reasonable care for the safety of his students.
Mr Summerfield of Moorland Avenue, Crosby was bailed until his trial on 27 September.
