HELENA, Mont. -

State corrections officials are responding to a survey that finds Montana State Prison has one of the nation's highest rates of inmate rape and staff sexual misconduct.
    
The inmate survey by the U.S. Department of Justice shows 9 percent of the 191 Montana respondents reported inmate-on-inmate sexual victimization from 2011-2012.
    
Nearly 10 percent reported sexual misconduct by prison guards.
    
That places the state prison as one of 11 nationwide with high rates of sexual victimization.
    
Department of Corrections Director Mike Batista and warden Leroy Kirkegard testified Wednesday before a Justice Department review panel. Batista questions the methodology of the survey, saying it depends on a small sample of anonymous inmates whose claims can't be verified.
    
He says gaps in policies and procedures have been addressed over the last year.
