The Douglas County Sheriff's Office said in a tweet that officials are still "in (the) process of identifying and locating shooter(s)" in the incident at STEM School Highlands Ranch in Highlands Ranch. The office called the scene "unstable" and "active."
STEM School Highlands Ranch is located about 7 { miles southeast of Columbine High School, where 13 people were killed on April 20, 1999.
Local outlet KMGH reported that one suspect was down and authorities were continuing to look for two other suspects.
Calls to the sheriff's office by the New York Daily News were not immediately returned.
"Unstable situation, shots fired at STEM school at Ridgeline and Plaza. Avoid area," the office wrote in another tweet. Authorities first responded to shots fired at 1:53 p.m. local time.
The charter school runs from kindergarten to 12th grade and serves 1,800 students, according to KMGH.
Kelley Paulson, the mother of two students at the school, told the news outlet she first heard about the shooting through a text message from a friend who was in the school.
"She said 'guns, shooting, oh my god, oh my god.' And she could hear them and that's how I first knew," she said. "The next thing I know, I heard my son, who is calling me because all of the kids who were in middle school ... all immediately ran out of the building."
