Barbara Jeanne Anderson, a former Kentlake math teacher, trial will start on Sept. 12 for a charge of first-degree sexual misconduct.

The King County Prosecutor’s office filed the charge against Anderson on April 4 after it was discovered in March that she allegedly had an inappropriate relationship with one of her male students.

Anderson pleaded not guilty to the charge in April.

If convicted, Anderson could face six months to a year in jail.

According to the prosecutor’s probable cause document, the relationship was discovered after the boy’s mother found hundreds of text messages between the two in the space of about three weeks.

School district officials contacted the King County Sheriff’s Office March 8, and an investigation began, which resulted in Anderson’s arrest March 17. She was released the next day.

An ongoing relationship through text messages and a social networking website allegedly led to sexual contact between Anderson and the boy, according to the probable cause document.

The statute used in this case is written to prohibit teachers (or other school employees) from having sexual intercourse with students who are 16 or 17 years old, when the employee is at least five years older than the student.

The age of consent for a sexual relationship is 16 in Washington state.

A pre-trial hearing is set for Aug. 12.
