A list of certified employees offering tutoring, services or private lessons is kept by the Curriculum Services Department. The availability of this list is intended to allow parents/guardians to obtain desired services from persons other than the employee to whom the student is currently assigned. It is understood that tutoring, services, or private lessons are outside the scope of an employee’s contract with the School District. Therefore, the District will not provide supervision of the employee, nor will District employees become involved in mediating disputes which arise during tutoring, services or private lessons.
