# 404.1645 How and when we determine whether the performance accuracy standard is met.

(a) *How we determine performance accuracy.* We determine a State agency's performance accuracy rate on the basis of decision and documentation errors identified in our review of the sample cases.

(b) *Frequency of review.* Title II and title XVI initial performance accuracy are monitored together on a quarterly basis. The determinations as to whether the performance accuracy threshold has been met is made at the end of each quarter each year. Quarterly State-by-State combined initial performance accuracy rates are compared to the established threshold level.
