A female teacher was arrested on allegations of sexual assault on a student in exchange for providing him with favorable grades.

Lena Stewart, a 26-year-old teacher at Nixa High School in Missouri, has been charged with multiple counts of statutory sodomy and statutory rape, as well as sexual contact with a student and sexual misconduct, according to the KY3 news channel.

The accusations pertain to alleged incidents that took place in October 2022. The student involved was 16 years old at the time, and in the state of Missouri, the legal age for consenting to sexual activity is 17.

According to investigators, the student reported that Stewart was amiable toward him in class.

He claimed that he didn't have to exert much effort to receive an A and expressed worries that his grades might decline if he did not comply with her sexual advances.

A police report said: "CV was interviewed as the CAC in October 2022. Lena and CV arranged to meet while CV was visiting a friend for the evening."

"CV told the interviewer that on two separate occasions, Lena met them at their friend's house and the two engaged in sexual contact."

"In both instances, Lena arrived in her vehicle and CV got into the vehicle with her. During the first contact, CV said the two kissed and undressed."

"CV said they got uncomfortable and told Lena that they needed to go home. During the second meet-up, CV said they kissed, undressed, performed oral sex on each other, and engaged in sexual intercourse."

In December, Stewart was placed on administrative leave by the Nixa School District.

In a statement, Zac Rantz, a representative of the education authority, stated: "We learned today that charges have been filed against Lena Stewart, a teacher at Nixa High School."

"We take any allegation of inappropriate conduct extremely seriously, so when an allegation was made in December, the district followed policy and procedure and then placed Lena Stewart on administrative leave and will continue to follow board policy and procedure when addressing this situation."

"The district will be working with the appropriate authorities as they conduct their investigation and will cooperate fully with anything they need."
