The Kentucky Parole Board Monday ordered Michael Carneal to spend the rest of his life in prison for his shooting massacre at Heath High School in West Paducah in which he killed three fellow students and injured five.
The serve-out ruling means Carneal, 39, will never be considered for parole again.
All seven members present voted for a serve-out.
Chair Ladeidra Jones told Carneal that "due to the seriousness of the crime" and because "lives were taken, it is the decision of the parole board" that "you will serve out your sentence."
In a statement, the parole board said its decision was made "in compliance with Kentucky law and in an effort to maintain a delicate balance between public safety, victim rights, reintegration of the offender and recidivism."
She said the board is prohibited by law from discussing its deliberations as they occurred in closed session.
Given the large number of victims, it was unlikely that Carneal would be freed. But he may have eliminated any chance of that when he testified last week that he still hears voices in his head - like the ones he said told him to open fire on Dec. 1, 1997.
Though he said he can resist those voices now, a parole board member said his prognosis was poor and that he was experiencing "paranoid thoughts with violent imagery."
He said on Sept. 20 that he had heard voices two days earlier telling him to jump down a stairway.
Heath High School shooting:Kentucky school shooting survivors say Michael Carneal sentenced them to life of suffering
Carneal opened fire on a prayer circle gathered before school with a semi-automatic pistol he had stolen from a neighbor's garage.
It was one the first mass school shootings in the United States, coming 17 months before Eric Harris and Dylan Klebold killed 12 students and one teacher and injured 21 more at Columbine High School in Colorado.
Carneal pleaded guilty to murder, attempted murder and burglary of the gun and was sentenced to life. But because he was only 14 at the time, he was entitled to parole consideration after 25 years.
He was believed to be one of the first school shooters to come up for parole; the rest died in their attacks or were condemned to life.
His father, John Carneal, had pleaded for his release, citing his age at the time of the crime. And he and his wife offered to take him into their home and ensure he continued to get mental heath treatment.
He was diagnosed with paranoid schizophrenia and takes three medications for it, he testified.
But his victims and their families testified that there is no guarantee he would continue to take it after he was released.
All but one testified against paroling him.
Asked if he deserved parole, Carneal said: "I don't know: Sometimes I think I deserve to be killed." But he said he would "like to do something good for society - even if it is just to listen people."

He killed three fellow students - Kayce Steger, 15, Nicole Hadley, 14, and Jessica James, 17, and injured Missy Jenkins Smith, who was paralyzed from the chest down; Hollan Holm, Shelly Schaberg, Kelly Hard Alsip and Craig Keene.
Jenkins Smith, who visited Carneal in prison, said she had forgiven Carneal but that "he is doing well behind bars and he should stay there.
"Why mess with something that isn't broken?" she said in an interview.
Nicole Hadley's mother, Gwen, told the board that "Nicole didn't get a second chance. The shooter should stay where he is."
Andrew Hadley, her younger brother, said he has suffered from anxiety and depression since she was gunned down and struggles to come up with an answer when his own daughter, 5, asks when she is going to meet her Aunt Nicole.
