The Stratford High School assistant band director who was fired after allegedly having sex with a male student appeared before a judge Monday to hear charges in her case.

Michelle Strickland, 23, was arrested and charged with improper relationship with a student after officials received an anonymous tip that she was having an inappropriate relationship with an 18-year-old band student.

Spring Branch ISD says Strickland served during the 2013-14 school year, and was removed from the classroom and away from contact with students after the allegations surfaced.

Court documents state the teen said during the spring 2014 semester he engaged in sexual relations with Strickland in a storage room in the Stratford band hall.

Investigators say the student told them he also had sex with Strickland over spring break at his home around March 19.

The principal told investigators he reviewed the student’s phone communication between the teen and the teacher that suggested an ongoing sexual relationship and she was fired.

“Spring Branch ISD’s number one priority will always be the safety of our students. We will take swift and decisive action against any employee who ever endangers a student. This type of behavior will never be tolerated in Spring Branch ISD. The bond of trust between our parents and students and the employees of the school district is critically important,” a district statement read.

A judge ordered Strickland to not have any contact with the student in the case. She also can’t teach anyone under the age of 18 until the case is resolved.
