California Code, Education Code - EDC § 48917

(a) The governing board, upon voting to expel a pupil, may suspend the enforcement of the expulsion order for a period of not more than one calendar year and may, as a condition of the suspension of enforcement, assign the pupil to a school, class, or program that is deemed appropriate for the rehabilitation of the pupil.  The rehabilitation program to which the pupil is assigned may provide for the involvement of the pupil's parent or guardian in his or her child's education in ways that are specified in the rehabilitation program.  A parent or guardian's refusal to participate in the rehabilitation program shall not be considered in the governing board's determination as to whether the pupil has satisfactorily completed the rehabilitation program.

(b) The governing board shall apply the criteria for suspending the enforcement of the expulsion order equally to all pupils, including individuals with exceptional needs as defined in Section 56026.

(c) During the period of the suspension of the expulsion order, the pupil is deemed to be on probationary status.

(d) The governing board may revoke the suspension of an expulsion order under this section if the pupil commits any of the acts enumerated in Section 48900 or violates any of the district's rules and regulations governing pupil conduct.  When the governing board revokes the suspension of an expulsion order, a pupil may be expelled under the terms of the original expulsion order.

(e) Upon satisfactory completion of the rehabilitation assignment of a pupil, the governing board shall reinstate the pupil in a school of the district and may also order the expungement of any or all records of the expulsion proceedings.

(f) A decision of the governing board to suspend an expulsion order does not affect the time period and requirements for the filing of an appeal of the expulsion order with the county board of education required under Section 48919.  Any appeal shall be filed within 30 days of the original vote of the governing board.
