Section 715:10-3-1 - Requirements for creditable service

(a) All members of TRS must be employed a specified amount of time as related to their educational employment position, and earn a minimum salary, before creditable service will be awarded. A school\employment year typically falls between July 1 and June 30 of any year. No service performed as an unpaid volunteer shall be counted as service credit. For service performed on or after July 1, 2013, creditable service will be awarded based upon the information provided by each employer certifying full-time equivalent for each position, subject to approval by TRS. No member shall receive one (1) year of service credit for less than 960 hours of employment. (This does not mean that a member working 960 hours is automatically entitled to receive one (1) year of creditable service.) No more than one (1) year of creditable service shall be awarded for all service in any one (1) school year. For service performed on or after July 1, 2013, fractional service will be awarded for less than full-time employment performed during the contract year.

(b) For service performed from July 1, 2016, through June 30, 2019, service credit will be the result of the days the employee worked during the employment year divided by the number of days the full-time equivalent for that position would be required to work during the entire employment year. A member employed in a position where the full-time equivalent is required to work at least 6 hours per day, 30 hours per week, and 8 months per year shall be considered a full-time employee.

(c) For service performed from July 1, 2016, through June 30, 2019, the fractional service credit awarded for part-time employment will be based on the number of hours the employee works per week divided by the number of hours the full-time equivalent for that position would be required to work per week. A member employed less than 6 hours per day, 30 hours per week, or 8 months in a year shall be considered a part-time employee. If the employee works less days per week or employment year than the full-time equivalent, fractional service will also be awarded based on the number of days the employee works in the employment year divided by the number of days the full-time equivalent works during the employment year.

(d) For service performed on or after July 1, 2019, the formula used to calculate service credit will be applied in the same manner for both full-time and part-time employment. The minimum requirement for full-time employment is 6 hours per day, 30 hours per week, and 8 months per year. Service credit will be reduced if the employee works less than the minimum requirement for full-time employment or less than the full-time equivalent for the position worked. Service credit will be calculated by multiplying the full-time equivalent percentage by the employment year percentage as follows:

(e) For service performed on or after July 1, 2016, service credit of less than 1.0 shall be rounded to the nearest tenths (. 4 hundredths and lower will round down, and . 5 hundredths and higher will round up).
