He was suspended on full pay while an investigation was completed.
A year-long investigation by the school, led by an independent investigator, found he had behaved inappropriately and the teacher was fired from his job in June for serious misconduct.
During the course of the investigation it was also discovered that the teacher had downloaded pornography onto his work computer.
The teacher has since taken his dismissal to the ERA, saying he was unjustifiably dismissed and was seeking interim reinstatement while his dismissal was investigated.
The school's Board of Trustees opposed interim reinstatement.
Findings released today found he would not be reinstated in the interim, pending a full investigation into his dismissal.
