A Van Alstyne Middle School assistant principal has been put on administrative leave after an arrest in Collin County this week for alleged child sex abuse.

Collin County jail records show Kirby Glynn Smith, 50, was arrested by McKinney Police Tuesday and has been charged with continuous sexual abuse of a child — a first-degree felony. In a social media post published Wednesday, Van Alstyne Independent School District Superintendent David Brown confirmed the arrest of an employee, but did not directly name Smith.

“It is with a saddened heart we acknowledge that the Van Alstyne ISD administration received a report from the McKinney Police Department that an employee was arrested and charged with sex abuse of a child,” Brown said in the statement. “Van Alstyne ISD is fully cooperating with law enforcement in the Collin County investigation. The employee is on administrative leave and is not allowed on Van Alstyne ISD property.”

Van Alstyne ISD administrators did not immediately respond to a request for additional comment Wednesday, but the McKinney Police Department issued a brief statement and described the victim as a juvenile male. The department also said Smith was a teacher at Cockrill Middle School in McKinney at the time of the alleged offense.

No other victims are currently known. Smith was named 2012 Teacher of the Year for Cockrill Middle School and recognized as one of 27 "Math Heroes" by U.S. defense contractor the Raytheon Company in 2014 for "creative and interactive techniques to make math real and relatable" for students.

“We believe our number one priority is maintaining the safety and security of our students,” Brown said in his statement. “Due to the fact that this is an ongoing investigation, we have very little information at this time.”

Smith remains in custody Wednesday afternoon on $500,000 bond. It wasn’t immediately clear whether he had secured representation. As of Wednesday afternoon, Smith did not appear among the listing of staff pictures and email addresses on the Van Alstyne Middle School website.

His Texas Educator Certificate on file with the Texas Education Agency shows Smith holds valid certifications to serve as a principal, as well as to teach mathematics and general classes for grades four through eight, English as a second language supplemental for grades four through 12 and mathematics for grades seven through 12.
