John Jay High School Teacher Chad Allen Rodriguez Arrested on Felony Charge of Improper Relationship with Student, NISD Says

A John Jay High School physics and astronomy teacher and coach has been arrested on a felony charge of improper relationship between an educator and a student, district officials confirmed.

Chad Allen Rodriguez, 38, was taken into custody Saturday and booked into the Bexar County Jail, where he remains held on a $50,000 bond, according to the Northside Independent School District (NISD). Rodriguez, who has been with the district since August 2016, teaches physics and astronomy and serves as a football and track coach at the San Antonio school.

The district said it was notified of allegations involving Rodriguez and a student and is fully cooperating with law enforcement in the ongoing investigation. As a result of his arrest, Rodriguez has been placed on immediate administrative leave.

According to the arrest affidavit, the incident came to light after a student walking near Rodriguez’s classroom on May 14 observed him alone with a minor inside. That student reported what they saw to school staff, prompting an investigation.

During interviews with authorities, the teen, identified as 17 years old, alleged that she met Rodriguez in October 2025 and that their relationship escalated over time. The affidavit states that it began with eye contact and flirting in the classroom and later included kissing and sexual intercourse multiple times throughout the school year.

Authorities also allege that Rodriguez exchanged cell phone numbers with the student, sending and receiving explicit photos. Surveillance footage reportedly shows the student entering his classroom and remaining there for approximately 10 minutes on one occasion.

In a written statement, NISD said, “The district is aware of the allegations and subsequent arrest, and the employee has been placed on immediate administrative leave. Our priority remains the safety and well-being of our students.”

The investigation is ongoing, and authorities have not released additional information regarding potential charges beyond the felony improper relationship allegation.
