A teacher and coach in the Northside Independent School District was jailed after allegedly having sex with a 17-year-old female student on campus.
Chad Allen Rodriguez, 38, was arrested Saturday and charged with improper relationship between educator and student, a second-degree felony punishable by 2 to 20 years in prison.
Rodriguez is a physics teacher and football and track coach at John Jay High School.
He was immediately placed on administrative leave, according to Northside ISD.
The San Antonio Police Department made the arrest and warned Rodriguez may have more victims.
Rodriguez was booked into the Bexar County Adult Detention Center on May 16. Bond was set at $50,000.
According to an arrest affidavit obtained by KSAT, a student spotted Rodriguez through a window alone in a classroom with the girl on March 14 and told another student, who reported it to school staff. School surveillance video confirmed the student going into Rodriguez’s classroom as reported.
The girl told investigators she met Rodriguez in October 2025. He was her coach and astronomy teacher.
The student said the relationship started with flirting in the classroom, then escalated to physical contact, according to the affidavit. The girl said she and Rodriguez also exchanged explicit photos via cell phone.
Rodriguez allegedly had sexual intercourse with the student multiple times throughout the school year, both on and off campus.
Online records show Rodriguez has worked for Northside ISD since the 2016-17 school year.
Rodriguez holds a teaching certificate for physical education and science, which is currently under review by the Texas Education Agency.
A statement from Northside ISD confirmed that Rodriguez was hired in August 2016 and is a physics and astronomy teacher and a football and track coach at Jay High School.
“The district is aware of the allegations and subsequent arrest, and the employee has been placed on immediate administrative leave,” the district stated.
While we cannot share specific details due to the ongoing police investigation, NISD and Jay High School are cooperating fully with law enforcement. Our priority remains the safety and well-being of our students, and we are committed to maintaining a secure, supportive environment during this time.
In the past few years, hundreds of Texas school employees have been accused of sex crimes involving students and other children—including in Northside ISD.
In April 2026, elementary teacher Cecilia Mueller was charged with continuous sexual abuse of a 5th-grade student that allegedly occurred during the 2016-17 school year.
In 2023, Warren High School teacher and coach Stephanie Woods was arrested for having an improper relationship with a female student. Also in 2023, O’Connor High School teacher David Vetters was sentenced to more than 10 years in prison after pleading guilty to planning and facilitating the 2017 sexual assault of a 12-year-old child who was being abused by another man.
Thousands of educators have been reported to the TEA for sexual misconduct since the state began keeping organized records.
The TEA’s new Educator Misconduct Reporting Dashboard shows that the agency has opened 2,059 sexual misconduct investigations in the first eight months of fiscal year 2026, compared to 1,042 investigations in all of 2025.
