California Code, Education Code - EDC § 48900.1

(a) The governing board of each school district may adopt a policy authorizing teachers to require the parent or guardian of a pupil who has been suspended by a teacher pursuant to Section 48910 for reasons specified in subdivision (i) or (k) of Section 48900, to attend a portion of a schoolday in the classroom of his or her child or ward. The policy shall take into account reasonable factors that may prevent compliance with a notice to attend. The attendance of the parent or guardian shall be limited to the class from which the pupil was suspended.

(b) The policy shall be adopted pursuant to the procedures set forth in Sections 35291 and 35291.5. Parents and guardians shall be notified of this policy prior to its implementation. A teacher shall apply any policy adopted pursuant to this section uniformly to all pupils within the classroom.

The adopted policy shall include the procedures that the district will follow to accomplish the following:

(c) If a teacher imposes the procedure pursuant to subdivision (a), the principal shall send a written notice to the parent or guardian stating that attendance by the parent or guardian is pursuant to law. This section shall apply only to a parent or guardian who is actually living with the pupil.

(d) A parent or guardian who has received a written notice pursuant to subdivision (c) shall attend class as specified in the written notice. The notice may specify that the attendance of the parent or guardian be on the day the pupil is scheduled to return to class, or within a reasonable period of time thereafter, as established by the policy of the board adopted pursuant to subdivision (a).
