A 31 year-old Cowra man charged with break and enter at a local school was jailed for nine months at the Local Court on April 21.
Joshua Aaron McDonald entered a plea of guilty to the offence when he represented himself to answer the charge.
Sentencing magistrate Jillian Kiely imposed a non-parole period of five months.
The court was told that between 4pm on January 12 and 7.45am on January 27 this year McDonald had gained entry to a classroom at the Cowra school through an unlocked window and removed an Apple Mac computer.
He also removed a pair of denim jeans from a cupboard.
Forensic police had discovered fingerprints belonging to McDonald at the scene.
Two sets of prints were found on the exterior and one set on the interior of a window McDonald had climbed through to gain entry.
When questioned McDonald told police he believed the fingerprints may have been on the window from when he was younger and "when I was breaking into schools and drinking".
The school's cleaner countered this argument stating that the windows at the school had been cleaned inside and out during the October school holidays.
Before sentencing McDonald, magistrate Kiely noted "he's had a number of opportunities to serve sentences in the community".
"He's back before the court for the same (type) of offence," she said before imposing the jail sentence.
