5. Each school district shall report to the department of education, in a manner prescribed by the department, an annual count of all incidents of violence that result in injury or property damage or assault by a student in a school building, on school grounds, or at a school-sponsored function, and any time a student is referred for the use of or transfer to a therapeutic classroom. The report shall include but not be limited to demographic information on students reported as victims and reported as perpetrators of incidents of violence that result in injury or property damage or assault, including but not limited to disaggregated information on race, gender, national origin, age, grade level, and disability, along with any other data required for the department to implement the federal Elementary and Secondary Education Act, as amended by the federal Every Student Succeeds Act, Pub.

A teacher or administrator who submits a report in accordance with this section and who meets the requirements of section 280.27 or section 613.21 shall be immune from civil or criminal liability relating to such action, as well as for participating in any administrative or judicial proceeding resulting from or relating to the report pursuant to the provisions of sections 280.27 and 613.21. The provisions of section 70A.29 shall apply to a teacher or administrator who submits a report in accordance with this section or who reports an incident of violence or assault to a local law enforcement agency in good faith and without fraudulent intent or the intent to deceive. Personal information regarding a student in a report submitted pursuant to this section shall be kept confidential as required under the federal Family Educational Rights and Privacy Act, 20 U.S.C. 1232g, and in the same manner as personal information in student records maintained, created, collected, or assembled by or for a school corporation or educational institution in accordance with section 22.7, subsection 1.

The procedures may include a provision which does not require a report when the school officials have determined that a school at-risk or other student assistance program would be jeopardized if a student self reports.
