(b) Functions performed pursuant to this article by certificated employees employed in a bargaining unit position shall not constitute either management or supervisory functions as defined by subdivisions (g) and (m) of Section 3540.1 of the Government Code.

(c) Teachers who provide assistance and review shall have the same protection from liability and access to appropriate defense as other public school employees pursuant to Division 3.6 (commencing with Section 810) of Title 1 of the Government Code.

(d) It is the intent of the Legislature that school districts be allowed to combine, by mutual agreement, their programs of peer assistance and review with those of other school districts.

(e) Not more than 5 percent of the funds received by a school district for the Peer Assistance and Review Program for Teachers may be expended for administrative expenses.  For the purposes of this article, administrative expenses shall include expenditures for the personnel costs of program administration and coordination, the cost of consulting teacher selection, and indirect costs associated with the Peer Assistance and Review Program for Teachers.
