Johnny Gonzales, 33, also pleaded guilty to aggravated sexual assault of a child, according to a story in Monday's edition of the Houston Chronicle.
The charges against Brandy Gonzales involve four students in the same fifth-grade class and a fifth boy from a different class in 2004 at Piney Point elementary, where she was a teacher.
Assistant District Attorney Denise Oncken has said the students alleged that Gonzales would touch them under desks during class.
The sexual contact escalated when Gonzales would meet the boys at a movie theater. Prosecutors said the boys' parents would leave them at the theater with Gonzales, thinking she was a good teacher.
The former teacher is accused of sexually assaulting one of the boys at her apartment. The husband also allegedly performed sex acts on the boy, according to Oncken.
The couple was arrested in December 2006.
A pre-sentence investigation has already been held. State District Judge Michael McSpadden is scheduled to sentence them in October.
