ACA measurement periods

Departments and hiring managers can use these measurement periods to determine benefits eligibility.

Initial period	Standard period
Non-benefits eligible employees hired on or after Oct. 1, 2013, will be measured to determine eligibility, beginning the first of the month following hire.	Non-benefits eligible employees continue to be measured to determine eligibility every year, Oct. 1 through Sept. 30.
If average 30 or more hours per week, offer health, life and disability coverage by the beginning of the 13th month; not eligible for tuition waiver or paid benefits leave plans. Coverage will continue for the initial stability period regardless of the number of hours worked per week during the stability period.	If average 30 or more hours per week, offer health, life and disability coverage during the Open Enrollment Periods; not eligible for tuition waiver or paid benefits leave plans. Coverage will continue for the standard stability period regardless of the number of hours worked per week during the stability period.

First standard measurement period after the initial measurement period: If an employee does not average 30 or more hours per week, coverage is canceled at the end of the initial stability period.
Subsequent standard measurement periods: If an employee does not average 30 or more hours per week, coverage is canceled at 11:59 pm at the end of the pay period in which Dec. 31 occurs.
