A former Colorado educator, once considered a contender for the 2025 state Teacher of the Year, has been sentenced to 14 years in prison following allegations of a sexual relationship with a student, as well as continued contact with the student after legal charges were filed against her.
Tera Johnson-Swartz, 45, who previously taught at STEM School Highlands Ranch and is also a writer, admitted guilt to charges of sexual exploitation of a child and cybercrime, the Douglas County Sheriff’s Office reported on March 19. The cybercrime charge was linked to her ongoing communication with the student involved.
The case came to light when the parents of a 16-year-old student discovered text messages containing sexual content in January 2025, as detailed by The Denver Post.
Johnson-Swartz, who had been acknowledged as one of the seven finalists for Colorado’s Teacher of the Year just five months prior to the investigation, faced charges in two distinct cases. The first case arose from a grand jury inquiry into the alleged relationship in early 2025, while the second related to her continued interactions with the student.

Documents show the relationship started with texting but quickly escalated, with Johnson-Swartz giving the student cigarettes, letting him use her marijuana vape pen, and eventually engaging in a physical relationship, the local outlet reported.
She was reportedly suspended from the school once the allegations surfaced and was later fired and banned from campus.
Less than a month later, the involved student was caught on camera leaving campus and getting into a car that matched Johnson-Swartz’s vehicle, according to CBS. The teen reportedly admitted to investigators that his former teacher had picked him up and driven him to a nearby neighborhood.
The incident sparked an investigation, and in February 2025, detectives with the Douglas County Sheriff’s Office Special Victims Unit arrested Johnson-Swartz on charges of kidnapping and contributing to the delinquency of a minor in connection with an inappropriate relationship with a student.

Johnson-Swartz secured a $100,000 bond with the assistance of a professional bondsman and was released the following day, the outlet said.
However, over the Fourth of July weekend that year, authorities were alerted by the student’s parents, who reported that the two were still in contact, according to CBS.

The two reportedly encountered one another for two consecutive nights and Johnson-Swartz began calling and texting in the days that followed.
Johnson-Swartz was arrested again. In addition to her prison sentence, she was reportedly ordered to complete six years of sex offender probation after her release, which includes registering as a convicted sex offender.
