(JTA) — David Kramer, a former teacher at the Yeshivah College day school in Melbourne, Australia, has been sentenced to three years and four months in prison for sexually assaulting four students.

Kramer, however, could leave prison after a little more than three months because he has been in prison while awaiting his sentence, according to Australian publication The Age.

Following the sentencing Wednesday, abuse survivor and advocate Manny Waks said, according to The Age, that the sentence was “”a little bit lower than we anticipated, but justice has been served.”

Kramer was convicted of sex abuse in the United States, but was extradited to Australia for the Yeshivah College accusations last year.

The abuse occurred between 1989 and 1992. All of Kramer’s victims were 10 or 11 years old.

Yeshivah College Principal Yehoshua Smukler, according to The Age, issued an apology after the sentencing for the school’s not informing police of the abuse allegations when they came to light.

The school “sincerely regrets and unreservedly apologizes for not informing the police at the time the allegations arose,” the statement read. “If any allegations were to arise today, they would be immediately reported to the police and the relevant authorities.”
