(5) A school district's discipline plan may provide that as an alternative to suspension, a student may remain in school by having the parent, guardian or custodian, with the consent of the student's teacher or teachers, attend class with the student for a period of time specifically agreed upon by the reporting teacher and school principal. If the parent, guardian or custodian does not agree to attend class with the student or fails to attend class with the student, the student shall be suspended in accordance with the code of student conduct and discipline policies of the school district.

The local school board shall adopt and make available to all teachers, school personnel, students and parents or guardians, at the beginning of each school year, a code of student conduct developed in consultation with teachers, school personnel, students and parents or guardians. The code shall be based on the rules governing student conduct and discipline adopted by the school board and shall be made available at the school level in the student handbook or similar publication. The code shall include, but not be limited to:

• (a) Specific grounds for disciplinary action under the school district's discipline plan;

• (b) Procedures to be followed for acts requiring discipline, including suspensions and expulsion, which comply with due process requirements;

• (c) An explanation of the responsibilities and rights of students with regard to: attendance; respect for persons and property; knowledge and observation of rules of conduct; free speech and student publications; assembly; privacy; and participation in school programs and activities;

• (d) Policies and procedures recognizing the teacher as the authority in classroom matters, and supporting that teacher in any decision in compliance with the written discipline code of conduct. Such recognition shall include the right of the teacher to remove from the classroom any student who, in the professional judgment of the teacher, is disrupting the learning environment, to the office of the principal or assistant principal. The principal or assistant principal shall determine the proper placement for the student, who may not be returned to the classroom until a conference of some kind has been held with the parent, guardian or custodian during which the disrupting behavior is discussed and agreements are reached that no further disruption will be tolerated. If the principal does not approve of the determination of the teacher to remove the student from the classroom, the student may not be removed from the classroom, and the principal, upon request from the teacher, must provide justification for his disapproval;

• (e) Policies and procedures for dealing with a student who causes a disruption in the classroom, on school property or vehicles, or at school-related activities;

• (f) Procedures for the development of behavior modification plans by the school principal, reporting teacher and student's parent for a student who causes a disruption in the classroom, on school property or vehicles, or at school-related activities for a second time during the school year; and

• (g) Policies and procedures specifically concerning gang-related activities in the school, on school property or vehicles, or at school-related activities.
