The trial of a former Nova Scotia teacher facing sex-related charges involving two teenaged boys has begun in Pictou.

Carolyn Amy Hood has been charged with one count of sexual assault, one count of sexual interference, two counts of luring minors over the internet for a sexual purpose, and two counts of sexual exploitation of a young person.

She has pleaded not guilty to all charges.

Pictou District RCMP started investigating Hood in the fall of 2013 after receiving a complaint from Thorburn Consolidated School.

The 39-year-old Stellarton woman was arrested in January 2014 following an 11-week police investigation.

The charges date from March through September of 2013 and allege sexual contact with two boys -- one under the age of 16 and the other under 18.

Hood taught Grade 6 at Thorburn Consolidated School at the time of the alleged offences, although they did not take place on school property.

Ten days have been set aside for the trial.
