(e) Each local and regional board of education shall develop, adopt and implement policies and procedures in conformity with section 10-154a for (1) dealing with the use, sale or possession of alcohol or controlled drugs, as defined in section 21a-240, as amended by this act, by public school students on school property, including a process for coordination with, and referral of such students to, appropriate agencies, and (2) cooperating with law enforcement officials. On and after January 1, 2022, no such policies and procedures shall result in a student facing greater discipline, punishment or sanction for use, sale or possession of cannabis than a student would face for the use, sale or possession of alcohol.

(b) Each local and regional board of education shall develop and implement a safe school climate plan to address the existence of bullying and teen dating violence in its schools. Such plan shall:

Whenever used in sections 10-233a to 10-233g, inclusive:

(a) Any local or regional board of education may authorize the administration of the schools under its direction to suspend from school privileges a pupil whose conduct on school grounds or at a school sponsored activity is violative of a publicized policy of such board or is seriously disruptive of the educational process or endangers persons or property or whose conduct off school grounds is violative of such policy and is seriously disruptive of the educational process. In making a determination as to whether conduct is seriously disruptive of the educational process, the administration may consider, but such consideration shall not be limited to: (1) Whether the incident occurred within close proximity of a school; (2) whether other students from the school were involved or whether there was any gang involvement; (3) whether the conduct involved violence, threats of violence or the unlawful use of a weapon, as defined in section 29-38, and whether any injuries occurred; and (4) whether the conduct involved the use of alcohol. Any such board may authorize the administration to suspend transportation services for a pupil whose conduct while awaiting or receiving transportation to and from school endangers persons or property or is violative of a publicized policy of such board. Unless an emergency exists, no pupil shall be suspended without an informal hearing by the administration, at which such pupil shall be informed of the reasons for the disciplinary action and given an opportunity to explain the situation, provided nothing herein shall be construed to prevent a more formal hearing from being held if the circumstances surrounding the incident so require, and further provided no pupil shall be suspended more than ten times or a total of fifty days in one school year, whichever results in fewer days of exclusion, unless such pupil is granted a formal hearing pursuant to sections 4-176e to 4-180a, inclusive, and section 4-181a. If an emergency situation exists, such hearing shall be held as soon after the suspension as possible.

(b) In determining the length of a suspension period, the administration may receive and consider evidence of past disciplinary problems which have led to removal from a classroom, suspension or expulsion of such pupil.

(c) Whenever any administration suspends a pupil, such administration shall not later than twenty-four hours after the suspension notify the superintendent or such superintendent's designee as to the name of the pupil against whom such disciplinary action was taken and the reason therefor.

(d) Any pupil who is suspended shall be given an opportunity to complete any classwork including, but not limited to, examinations which such pupil missed during the period of suspension.

(e) For any pupil who is suspended for the first time pursuant to this section and who has never been expelled pursuant to section 10-233d, the administration may shorten the length of or waive the suspension period if the pupil successfully completes an administration-specified program and meets any other conditions required by the administration. Such administration-specified program shall not require the pupil or the parent or guardian of the pupil to pay for participation in the program.

(f) Whenever a pupil is suspended pursuant to the provisions of this section, notice of the suspension and the conduct for which the pupil was suspended shall be included on the pupil's cumulative educational record. Such notice shall be expunged from the cumulative educational record by the local or regional board of education if a pupil graduates from high school, or in the case of a suspension of a pupil for which the length of the suspension period is shortened or the suspension period is waived pursuant to subsection (e) of this section, such notice shall be expunged from the cumulative educational record by the local or regional board of education (1) if the pupil graduates from high school, or (2) if the administration so chooses, at the time the pupil completes the administration-specified program and meets any other conditions required by the administration pursuant to said subsection (e), whichever is earlier.

(g) On and after July 1, 2015, all suspensions pursuant to this section shall be in-school suspensions, except a local or regional board of education may authorize the administration of schools under its direction to impose an out-of-school suspension on any pupil in (1) grades three to twelve, inclusive, if, during the hearing held pursuant to subsection (a) of this section, (A) the administration determines that the pupil being suspended poses such a danger to persons or property or such a disruption of the educational process that the pupil shall be excluded from school during the period of suspension, or (B) the administration determines that an out-of-school suspension is appropriate for such pupil based on evidence of (i) previous disciplinary problems that have led to suspensions or expulsion of such pupil, and (ii) efforts by the administration to address such disciplinary problems through means other than out-of-school suspension or expulsion, including positive behavioral support strategies, or (2) grades preschool to two, inclusive, if during the hearing held pursuant to subsection (a) of this section, the administration determines that an out-of-school suspension is appropriate for such pupil based on evidence that such pupil's conduct on school grounds is of a violent or sexual nature that endangers persons. An in-school suspension may be served in the school that the pupil attends, or in any school building under the jurisdiction of the local or regional board of education, as determined by such board. Nothing in this section shall limit a person's duty as a mandated reporter pursuant to section 17-101a to report suspected child abuse or neglect.

(a)(1) Any local or regional board of education, at a meeting at which three or more members of such board are present, or the impartial hearing board established pursuant to subsection (b) of this section, may expel, subject to the provisions of this subsection, any pupil in grades three to twelve, inclusive, whose conduct on school grounds or at a school-sponsored activity is violative of a publicized policy of such board and is seriously disruptive of the educational process or endangers persons or property or whose conduct off school grounds is violative of such policy and is seriously disruptive of the educational process, provided a majority of the board members sitting in the expulsion hearing vote to expel and that at least three affirmative votes for expulsion are cast. In making a determination as to whether conduct is seriously disruptive of the educational process, the board of education or impartial hearing board may consider, but such consideration shall not be limited to: (A) Whether the incident occurred within close proximity of a school; (B) whether other students from the school were involved or whether there was any gang involvement; (C) whether the conduct involved violence, threats of violence or the unlawful use of a weapon, as defined in section 29-38, and whether any injuries occurred; and (D) whether the conduct involved the use of alcohol.
