A new government report says crime rates in the nation's schools are about half what they were 10 years ago.
But the report also found that the rates have essentially leveled off, showing no change since 2000.
That mirrors the general trend in the United States, in which crime is at a 30-year low.
Some school safety experts credit the installation of metal detectors, hiring more security guards and paying more attention to bullying.
But others say the annual report routinely understates crime in schools because it is based on limited surveys and self-reporting.
They also say the data is already is outdated.
The report released today by the U.S. departments of Education and Justice found there were about 28 crimes of rape, sexual assault, robbery and physical assault for every one-thousand students in 2003. T
hat's down from 59 per one-thousand a decade earlier.
