John Jay High School Teacher Arrested for Sexual Relationship with Student

Physics Teacher Faces Serious Charges

Chad Allen Rodriguez was booked into the Bexar County Adult Detention Center on Saturday on an improper relationship between an educator and a student charge , marking another troubling case in San Antonio's education system. Rodriguez is a physics and astronomy teacher and a football and track coach at John Jay High School in the Northside Independent School District, where he was hired by NISD in August 2016 and has been placed on immediate administrative leave .

The case came to light when an unknown student was walking in the hallway on May 14 near Rodriguez's classroom when they allegedly saw the teen and Rodriguez alone in the classroom . This observation prompted an investigation that uncovered a disturbing pattern of inappropriate conduct spanning months.

Escalating Relationship Timeline

According to the arrest affidavit, the relationship began with eye contact and flirting in the classroom before it escalated to kissing and sexual intercourse, which allegedly occurred multiple times throughout the school year . The victim, a 17-year-old student, met regularly with Rodriguez in his classroom alone between October 2025 and May 2026 .

The inappropriate relationship extended beyond the classroom walls. The teen also told authorities that Rodriguez exchanged cell phone numbers with her and both would send explicit photos to each other . The arrest affidavit states Rodriguez and the student had multiple sexual relations on and off campus , indicating the severity and scope of the alleged misconduct.

Evidence and Investigation

Surveillance footage obtained by investigators allegedly showed the teen going into Rodriguez's classroom alone and remaining inside for about 10 minutes. The affidavit states another student is seen in the surveillance footage looking through the window, and the teen exits the classroom shortly after . This footage provided crucial evidence supporting the allegations.

On May 15, authorities responded to the campus in the 7600 block of Marbach Road for a case involving a teacher and a student . The NISD spokesperson said the district and the campus are fully cooperating with law enforcement , demonstrating the school's commitment to addressing the serious allegations.

Broader Pattern of Concern

This arrest represents part of a troubling trend affecting Texas schools. Similar cases have emerged across multiple districts in recent months, highlighting the urgent need for stronger safeguards and oversight in educational settings. The frequency of these incidents raises questions about screening processes, training protocols, and the effectiveness of current prevention measures.

For families in affected districts, these cases underscore the importance of open communication with children about appropriate boundaries and the need to report uncomfortable situations. Schools must balance maintaining trust and accessibility for students while implementing robust protections against predatory behavior. The investigation remains ongoing , and the case will likely influence future policies designed to protect students from exploitation by those in positions of authority.
