Four B.C. teachers have lost their teaching certificates after admitting to professional misconduct for everything from telephone sex with a student to voyeurism, the provincial teachers' college announced this month.

The information was published on the B.C. College of Teachers website as the colleges moves to comply with government orders to be more transparent about its discipline process.

Mark Edward Dyck lost his right to teach for two years when he admitted to developing an inappropriate relationship with a female student through e-mail and engaging in telephone sex with the girl.

"The communications included comments about having sexual intercourse with her as well as sexual fantasies he had that involved her," said the college statement.  No date was given for the incident.

Chi Yung Luu was a B.C. high school drama teacher when he was arrested on voyeurism charges in Washington state in 2005 for videotaping boys in a change room. He pleaded guilty and was sentenced to seven months in jail. After he served his time in a U.S. prison, Delta police arrested him for child pornography found in his B.C. home. He was given a 12-month conditional sentence.

The college will not issue Luu a teaching certificate "for an indeterminate period," according to the website.

Michael Rickards Hernandez admitted to conduct of an inappropriate sexual nature with a girl taking part in a theatre program where he was the teacher.

"Mr. Hernandez purchased and placed candies on parts of her face and removed them by using his mouth," said the college statement. No date was given for the incident. Hernandez pleaded guilty to a criminal charge of assault and was given a conditional discharge and 18 months probation.

He has agreed not to seek readmission to the college, the website said.

Howard Wallace Lee admitted to developing an inappropriate relationship with a female international student.

 "Mr Lee gave the student a card bearing a personal, handwritten message expressing his love for her … gave her gifts and engaged in French kissing with her on two separate occasions," said the notification. 

His certificate of qualification was cancelled.
