The principal may further disseminate the information regarding a petition, after the juvenile has been taken into custody, whether or not the child has been released, only to those students and school personnel having direct contact with the juvenile and need of the information to ensure physical safety or the appropriate educational placement or other educational services. If the division superintendent believes that disclosure of information regarding a report received pursuant to § 66-25.2:1 to school personnel is necessary to ensure the physical safety of the juvenile, other students, or school personnel within the division he may disclose the information to the principal of the school in which the juvenile is enrolled. The principal may further disseminate the information regarding such report only to school personnel as necessary to protect the juvenile, the subject or subjects of the danger, other students, or school personnel.
