(b) Prior to granting a license to or otherwise approving any individual to care for children in either a family day care home or a day care center, the department shall check the Child Abuse Registry pursuant to paragraph (3) of subdivision (b) of Section 11170 of the Penal Code. The Department of Justice shall maintain and continually update an index of reports of child abuse by providers and shall inform the department of subsequent reports received from the child abuse index pursuant to Section 11170 of the Penal Code and the criminal history.

The investigation shall include, but not be limited to, the review of the investigation report and file prepared by the child protective services agency that investigated the child abuse report. The department shall not deny a license based upon a report from the Child Abuse Registry or based on child abuse and neglect complaint records of the county child protective services agency unless child abuse is substantiated.

On and after July 1, 1993, the department shall implement this section for records maintained by all counties.
