A female Texas teacher and coach indicted on charges of having sex with a 15-year-old girl at her school has officially resigned, according to local media reports.

The charges, stemming from an alleged sexual relationship between 39-year-old Jennifer Lea Burton and one of her junior high school students, include three counts of sexual assault and three counts related to an improper relationship between student and educator, KFDM.com reported.

The purported sexual encounters between Burton, who was a teacher and coach at Orangefield Junior High, and the teen lasted from September to November of 2008, according to the indictment filed last week.

The school district canceled a meeting this week intended to discuss Burton's future with the district after receiving her letter of resignation on Monday, KFDM said.

"The letter of resignation will enable Orangefield ... to move forward and attempt to put this unfortunate incident behind us," said school district Superintendent Philip Welch. "Every measure will continue to be taken to assure that students are educated in a safe and secure school environment."
