The Vermont state auditor says a review of the state's online sex offender registry has found critical errors in 11 percent of offender records.

Auditor Doug Hoffer said Wednesday that the errors call into question the reliability of the registry.

He says the audit found critical errors in 253 of the 2,340 records in the registry.

Hoffer says the state has taken action to improve the registry since a 2010 audit found what the-then auditor's office described as "sizeable errors," but he says progress has been mixed.

Corrections Commissioner Andy Pallito says he's pleased with the department's progress and says it will work to implement the auditor's recommendations. He says the department is working on a new information system that will help to streamline the process with few errors.
