10000.  (a) Notwithstanding any other provision of law, the Trustees
of the California State University and any school district or
community college district  may enter into an agreement for the
exchange of personnel between the state university and the district.
   (b) The governing board of any school district, or community
college district, a county board of education, or the State
Department of Education may execute a contract with any California
teacher-training institution whereby certificated personnel of the
school district, county, or the State Department of Education may be
assigned to the teacher-training institution for full-time or
part-time duty for a period not to exceed one year.
   (c) Any teacher-training institution in California may execute a
contract with the governing board of any school district, or
community college district, a county board of education, or the State
Board of Education whereby certificated personnel of the institution
may be assigned to school districts, community college districts,
county boards of education, or the State Department of Education for
full-time or part-time duty for a period not to exceed one year.
   (d) Any such contract shall provide for the payment, by the entity
to which a person is assigned to the employer, of a sum equivalent
to the salary and other  employment costs of the employee.  In place
of that payment, the contract may provide for the exchange of
certificated personnel between the district, county, or State
Department of Education and the teacher-training institution.  Any
such employee shall retain his or her status as an employee of the
school district, community college district, county, State Department
of Education, or teacher-training institution  from which he or she
is assigned in all respects during the period of the assignment.
10001.  An agreement authorized by Section 10000 shall provide that
an employee of the California State University engaged in teacher
training may assume the duties of one of the certificated employees
of the district engaged in classroom teaching, and that the
certificated employee of the district may assume the duties of the
state university employee engaged in teacher training.
10003.  During such time as an employee has assumed duties in
another entity, pursuant to this chapter, he or she shall continue to
be an employee of the California State University, the school
district, or the community college district, as the case may be, for
all purposes, including, but not limited to, salary, membership in a
retirement system, tenure rights, and all other incidents of
employment.
