2. (2) Except as provided in OAR 459-005-0015(3), an active member accrues one month of retirement credit for each month in which the member performs service or receives paid leave as described in OAR 459-010-0011 for the major fraction of the month.

3. (3) An active member is presumed to have performed service for a major fraction of a month if:

   2. (b) The member starts employment on or before the 15th day of the calendar month and the employment continues through the end of the month;
   3. (c) The member starts employment on or before the first day of the calendar month and ends employment on or after the 16th day of the month; or

4. (4) A member or employer may seek to rebut the determination of creditable service based on the presumptions in section (3) by providing to PERS records that establish that the member did or did not perform service for a major fraction of a month as defined in subsection (1)(c) of this rule.

5. (5) An active member who is a school employee will accrue six months of retirement credit if the member performs service for a major fraction of each month of a school year when school is normally in session that falls between January 1 and June 30, and six months of creditable service if the member performs service for a major fraction of each month of a school year when school is normally in session that falls between July 1 and December 31.

   1. (a) School is presumed to be in session during the following dates:

      1. (A) For non-Higher Education employment, the first half of the school year is presumed to begin on or before September 15 and end on or after December 16;
      2. (B) For Higher Education employment, the first half of the school year is presumed to begin on or before September 26 for Higher Education employment and end on or after December 16;

   2. (b) If the school year falls outside the presumed dates described above, PERS must receive acceptable certification from the employer of the actual begin and end dates for each half of the school year.

   3. (c) An active member who is a school employee on leave of absence without pay may accrue retirement credit as follows:

      1. (A) If the period of leave of absence without pay falls outside the dates when school is presumed to be in session, the active member may accrue six months of retirement credit as described above.
      2. (B) If the leave of absence without pay falls within the dates when school is presumed to be in session, the active member may only accrue six months of retirement credit if the leave of absence constitutes less than the major fraction of the month, as provided in OAR 459-010-0010(3).
      3. (C) If the leave of absence without pay falls within the dates when the school year is in session, the active member may not accrue six months of retirement credit if the leave of absence constitutes the major fraction of the month, as provided in OAR 459-010-0010(3). Such member may accrue one month of retirement credit for each month in which the member performs service or receives paid leave for the major fraction of the month, as described in section (2) of this rule.
6. (6) A member may not accrue more than one month of retirement credit for any calendar month and no more than one year of retirement credit for any calendar year.

7. (7) Credit for the six-month waiting period required by OAR 459-075-0010(2).
