(h) For purposes of this section, a "principal's designee" is one or more administrators at the schoolsite specifically designated by the principal, in writing, to assist with disciplinary procedures.
In the event that there is not an administrator in addition to the principal at the schoolsite, a certificated person at the schoolsite may be specifically designated by the principal, in writing, as a "principal's designee," to assist with disciplinary procedures. The principal may designate only one person at a time as the principal's primary designee for the school year.
An additional person meeting the requirements of this subdivision may be designated by the principal, in writing, to act for purposes of this article when both the principal and the principal's primary designee are absent from the schoolsite. The name of the person, and the names of any person or persons designated as "principal's designee," shall be on file in the principal's office.
This section is not an exception to, nor does it place any limitation on, Section 48903.
