The Teaching Regulation Agency (TRA) panel heard he gave pupils gifts including condoms and that he sent a Valentine’s Day card to a pupil containing an inappropriate message.
A panel found his behaviour “was not a momentary lapse of judgement but was a calculated course of action in pursuit of sexual gratification”.
In a written statement, which he submitted to the TRA in 2023, Shilling said he was “deeply apologetic and upset for any hurt, anxiety or stress” caused.
But the TRA’s panel said his apology was “self-serving” and did not recognise the severity of his misconduct.
In a statement, the school’s spokesperson said: “The safety of our students is our highest priority.
“As soon as safeguarding concerns were raised about a member of teaching staff, we acted immediately by suspending the individual and raising a report to the TRA.
“We are reassured by the resolution of this case and will continue to uphold the most rigorous safeguarding standards.”
