safety; school procedures;
criminal classification

Purpose

Requires each
school district governing board (governing board) to adopt a public school
safety policy that meets outlined requirements, including requirements on a
school district superintendent to notify parents, employees and law enforcement
officers (LEOs) of any incident involving life-threatening violence as
specified. Requires each school district to annually post a public safety
report that includes outlined information and data relating to the number of
incidents that occurred in the three immediately preceding school years.
Determines that a school district superintendent and each governing board
member who violates the prescribed public safety policy requirements is guilty
of a class 1 misdemeanor. Designates this legislation as
Michael's Law
.

Background

Each governing board and charter school governing body (governing body) must
prescribe and enforce policies and procedures for school personnel to report:
1) any suspected crime against a person or property that is a serious offense
or� involves a deadly weapon or dangerous instrument or serious physical injury;
and 2) any conduct that poses a threat of death or serious physical injury to
an employee, student or other person on the school property. The policies must prescribe
a process for employees to document and report the conduct, including
specifying the employees responsible for making a report to the local law
enforcement agency (LEA). Each governing board and governing body must also prescribe
and enforce policies and procedures that require the school district or charter
school to notify the parent or guardian of each student who is involved in a
suspected crime or other outlined conduct, subject to the requirements of
federal law. A person who violates the outlined reporting requirements may be
disciplined for violating the governing board's or governing body's policies and
may be subject to dismissal (
A.R.S.
� 15-153
).

Each governing board must prescribe and enforce policies and procedures
that prohibit a person from carrying or possessing a weapon on school grounds
unless the person is a peace officer or has obtained specific authorization
from the school administrator (
A.R.S.
� 15-341
).

There is no anticipated fiscal impact to the state General Fund
associated with this legislation.

timely notification to students' parents and school employees of incidents that
involve life-threatening violence, threats of life-threatening
violence or threats that involve a deadly weapon or dangerous instrument as
defined in section 13-105, Arizona Revised Statutes, is essential to
protect student safety.

2. A school district's
escalation of incidents that involve a deadly weapon or dangerous instrument as
defined in section 13-105, Arizona Revised Statutes, to law enforcement
officers is ministerial and not discretionary.

3. A school district
official's knowing or intentional failure to comply with escalation or
notification requirements for public safety incidents endangers students and
undermines public trust.

4. Criminal classification
is appropriate when a school district official knowingly or intentionally fails
to perform the official's public safety duties as prescribed by law.
