RCW 41.32.345 provides an optional method of computing earnable compensation for part-time TRS Plan 1 members. This method is intended to ensure that a TRS Plan 1 member who earns a fractional year of service credit will receive benefits proportional to benefits received by a member who earns a full year of service credit.

(1) To be eligible for the alternate calculation, you must meet the requirements in subsection (2) or (3) of this section for:

(a) Each fiscal year for two consecutive fiscal years; or

(b) Each of the two twelve-month periods contained in an alternate period, provided that you meet the qualifications for using an alternate period for the calculation of your AFC under WAC 415-112-430(2).

(2) Service for a single employer. If you work for one and only one employer during the twelve-month period, you must satisfy the requirements of (a), (b), and (c) of this subsection.

(a) Written contract.

(i) If you work for a school district or educational service district, you must be under a part-time contract from the first teaching day to the last teaching day of the school's official calendar.

(ii) If you work for a community or technical college, school for the blind, or school for the deaf, you must be under part-time contracts for at least three of the four academic quarters (summer, fall, winter, or spring).

(b) Instructional position. You must spend more than seventy-five percent of your total hours of service as a classroom instructor (including office hours), a librarian, a psychologist, a social worker, a nurse, a physical therapist, an occupational therapist, a speech language pathologist or audiologist, or a counselor.

(c) Number of days. During the twelve-month period, you must be employed at least twenty days or the equivalent, but less than eighty percent of the days in your employer's official calendar. For purposes of this calculation, the department considers that the official calendar of a school district or educational service district has one hundred eighty days.

(3) Service for two or more employers. If you work for more than one employer during the twelve-month period, you must satisfy the requirements of (a), (b), and (c) of this subsection.

(a) Written contracts. You must be employed only under part-time contracts with a school district, educational service district, community or technical college, school for the deaf, or school for the blind for the equivalent of three of the four academic quarters (summer, fall, winter, or spring).

(b) Instructional position. You must spend more than seventy-five percent of your total hours of service as a classroom instructor (including office hours), a librarian, a psychologist, a social worker, a nurse, a physical therapist, an occupational therapist, a speech language pathologist or audiologist, or a counselor.

(c) Number of days. During the twelve-month period, you must be employed at least twenty days or the equivalent, but less than eighty percent of the days in your employers' official calendars, as illustrated in the example. For purposes of this calculation, the department considers that the official calendar of a school district or educational service district has one hundred eighty days. The number of days in the official calendars of community and technical colleges may vary.

She worked 5.6% (10/180) of School District A's official calendar plus 60% (90/150) of Community College B's official calendar for a total of 65.6%.

(4) The department may consider additional information to determine if you meet the requirements in this section. Upon the department's request, employers must provide, without limitation, the following information:

(a) For school district employees, the salary schedule and related workload provisions, if any, adopted pursuant to RCW 28A.405.200 by the school district; and

(b) Documentation indicating:

(i) Whether your position is included on the employing district's salary schedule, in workload provisions, or in a collective bargaining agreement;

(ii) Whether your position has duties, responsibilities, workload requirements, or methods of pay similar to those of positions found in the district's schedule, workload provisions, or collective bargaining agreement;

(iii) When your position was created, and how long you held the position;

(iv) Whether you have previously retired under the provisions of chapter 41.32 RCW.
