According to a U.S. Government Accountability Office report released this month, there have been multiple instances nationwide of schools hiring sex offenders to fill teaching positions. In the 15 cases reviewed in the report, six of those employees went on to abuse children at the school where they were hired.
Approximately 38 states require criminal background checks for public schools employees, while requirements for private schools vary. Kansas and Montana do not require background checks for any school employees, the New York Daily News reports.
In several cases, schools have allowed sex offenders to resign from their jobs and have even provided letters of recommendation on their behalf. This practice allows a sex offender to seek employment at another district, says the news source.
