Mark Craster-Chambers

Introduction

Mark Craster-Chambers is a former teacher at John Ruskin School in Coniston, Cumbria, who was banned from teaching for life in August 2022 after a Teaching Regulation Agency panel accepted his convictions for two offences of engaging in sexual activity while in a position of trust — offences committed against a former pupil of the school who complained to police in 2017. Craster-Chambers, who had taught at John Ruskin from 2001 to 2005 and later held other teaching posts, pleaded not guilty and was convicted after trial at Carlisle Crown Court, receiving concurrent prison sentences of six and eighteen months. He attended the regulatory hearing in person, unrepresented, and gave sworn evidence but did not accept the factual allegations behind the convictions.

Background Information

Craster-Chambers taught at John Ruskin School from September 2001 to August 2005, then moved through a number of other teaching posts. In 2017 — more than a decade after he had left the school — a former pupil complained to police that she had engaged in sexual activity with him while the position-of-trust relationship applied. A police investigation followed, and he was charged with two offences of engaging in sexual activity (other than sexual intercourse) with a person under 18 when in a position of trust, contrary to the Sexual Offences Act 2003. The police referral also brought the matter to the TRA.

He pleaded not guilty. After a trial, a jury convicted him of both counts on 4 March 2021 at Carlisle Crown Court. On 16 April 2021 he was sentenced to six months and eighteen months’ imprisonment, to run concurrently, was placed on the Sexual Offenders Register for ten years, and was put on the DBS Barring List — the separate safeguarding mechanism that already barred him from work with children regardless of the teaching ban.

The Controversy or Incident That Led to Their Cancellation

Convicted after trial of two position-of-trust sexual offences against a former pupil; contested the facts at the TRA but the certificate of conviction was conclusive.

At the hearing on 8 August 2022 at Cheylesmore House in Coventry, Craster-Chambers accepted he had been convicted of the offences but did not accept the factual allegations behind them, and gave sworn evidence to that effect. The panel was bound by the framework for conviction cases: where a teacher has been convicted of a relevant offence, the certificate of conviction is conclusive proof of both the conviction and the facts necessarily implied by it unless exceptional circumstances apply. The panel had before it a certificate from Carlisle Crown Court dated 4 February 2022 setting out his name, date of birth, the two counts, the sentence, the register requirement and the barring decision. No exceptional circumstances were found.

The panel found the allegation — conviction at any time of a relevant offence — proved, and the facts amounted to conviction of a relevant offence. His sworn denial of the underlying facts could not displace the jury’s verdict: the position-of-trust convictions by their nature establish that the sexual activity occurred within a relationship the 2003 Act protects, here teacher and former pupil. Because the victim’s identity and age are redacted from the published decision, the public record does not state when the relationship began, only that the complaint reached police in 2017 and the conduct predated it.

Public Reaction and Consequences

The decision records no press or social-media coverage of either the trial or the hearing; the Cumbrian local record of the 2021 sentencing is not part of the published decision. The panel recommended a prohibition order with no provision for a review period. In mitigation it considered only what was before it: his attendance, his sworn evidence, and nothing that spoke to insight — his position remained that the jury was wrong. The absence of any acceptance of responsibility weighed against any lesser outcome.

Decision maker Alan Meyrick agreed that a prohibition order was proportionate and in the public interest, and on 10 August 2022 — two days after the determination — decided that Craster-Chambers shall not be entitled to apply for restoration of his eligibility to teach. The combination meant the ban was the severest available: indefinite, with the restoration route closed.

Current Status

Craster-Chambers is prohibited from teaching indefinitely and cannot teach in any school, sixth form college, relevant youth accommodation or children’s home in England. The restoration right was removed at the point of the order, so the ban is permanent short of a successful High Court appeal within 28 days of notice. Independently of the teaching ban, his ten-year registration on the Sexual Offenders Register (from April 2021) and his placement on the DBS Barring List restrict any work with children across regulated sectors. The eighteen-month sentence, reduced by the customary early-release provisions, was served around the time of the regulatory hearing; he gave evidence in person in August 2022, a free man. The published decision is the standing public record of the convictions and the finding that he engaged in sexual activity with a former pupil while in a position of trust.

Impact on Their Career/Life

The ban ends any teaching career in England permanently, and the barring decision extends the exclusion beyond schools into any regulated children’s work. The case illustrates the position-of-trust offence’s long reach: the conduct’s relationship to his teaching role mattered even though the timeline sat more than a decade after he had left the school where the pupil knew him, and the 2017 complaint — twelve years after his John Ruskin departure — still produced a jury conviction on two counts. His decision to fight the facts at both trial and the TRA, without ever accepting the jury’s finding, cost him any mitigation that insight or remorse might have offered, and the decision maker closed the restoration door entirely rather than leaving a review period. For the victim, the 2017 complaint produced both a conviction and a published regulatory record naming the conduct.
