In a statement after the sentencing, the Police Service of Northern Ireland (PSNI) thanked the victims for their bravery in reporting the abuse.
“This man was an opportunist, using his position of power and trust within the school environment to prey on young girls,” said Det Insp Kelly Foley.
“He thought for a long time he had got away with this, today has proven that the passage of time has no bearing on a criminal justice outcome.”
She said the PSNI had seen an increase in reports of “non-recent child abuse” over the last five years.
“Sentencings like today, I hope, will provide those who have suffered with the confidence to break the years of silence they have endured,” the officer added.
The PSNI statement also included quotes from three of Lloyd-Lavery’s victims, all of whom urged others who have been abused to report the perpetrators.
They included Sarah, who is now 63 years of age, who said: “Speaking out is hard, but staying silent is harder.
“Today we got justice against a man who thought he had got away with it.”
