A Texas charter school teacher is in jail after being accused of sexually assaulting a 12-year-old student. The visiting international teacher had been reprimanded and then fired for placing his hands on students, but the school later rehired him.

International Leadership of Texas teacher Jose Adrian Hernandez Grimaldo, 46, was arrested last month and charged with one count of aggravated sexual assault of a child, a first-degree felony punishable by 5 to 99 years in prison.

At the time of the alleged assault, Hernandez Grimaldo taught at the ILTexas K-8 school in College Station. He later transferred to the school’s Lancaster K-8 campus where he worked at the time of his arrest.

According to an arrest report from the College Station Police Department, the female victim alleges the teacher attacked her in a bathroom in February 2023. She told police he threatened to kill her if she told anyone about the attack.

Hernandez Grimaldo denied the allegations, but according to a report by KBTX, he failed a polygraph test.

ILTexas Superintendent Eddie Conger confirmed in a statement Friday that, as a result of the arrest, Hernandez Grimaldo was terminated from ILTexas on May 24.

The ILTexas statement included a timeline of Hernandez Grimaldo’s employment with the school system.

Hernandez Grimaldo, who is in the U.S. on a teaching visa, was hired in August 2022 to teach Spanish at ILTexas’ College Station K-8 campus. According to the timeline, he cleared a standard background check and additional security clearance from the Department of Homeland Security.

He was placed on administrative leave and reprimanded in October 2022 for putting his hands on a student.

In March 2023, Hernandez Grimaldo was terminated from ILTexas following more complaints about him touching students.

He then filed a grievance and the district overturned his termination in May 2023.

The teacher was offered a transfer and began working at ILTexas Lancaster K-8 in August 2023.

In September 2023, a parent reported to the ILTexas College Station principal that inappropriate sexual interactions took place between their then-6th-grade student and Hernandez Grimaldo.

He was again placed on administrative leave in October 2023.

Superintendent Conger said ILTexas investigated but was unable to substantiate the sexual assault claims. Hernandez Grimaldo was reinstated as a teacher at ILTexas Lancaster K-8 in January 2024.

The superintendent said ILTexas filed “required reports with the local police department, Department of Family and Protective Services within 48 hours of initial notice, and the State Board of Education as appropriate.”

Conger directed all other questions regarding the investigation to the College Station Police Department.

Hernandez Grimaldo was first arrested in Dallas County on May 22. He was transferred into the Brazos County Jail on May 29 and is being held on a $200,000 bond.

His state-issued visiting international teacher certificate shows he is under investigation by the Texas Education Agency.

Hernandez Grimaldo is among dozens of Texas teachers charged with sex crimes involving students and children.
