Victoria's largest Jewish school will become the first in the state to employ armed guards, in a significant boost to its security.

From this week, guards with guns will be stationed at Mount Scopus Memorial College's three Melbourne campuses.

Principal Rabbi James Kennard said the decision to beef up security had not been triggered by a specific threat to the college.

"This enhancement of the guards' equipment reflects the heightened security levels now in place across Australia and worldwide, and is not in response to any particular threat to the College," he said in a statement.
