There are two types of grace periods:
A high-impact grace period, and
A low-impact grace period.
We establish a high-impact grace period when we expect the new, clarified, or changed policy or procedure to affect a large
We establish a low-impact grace period when we do not expect the new, clarified, or changed policy or procedure to affect
a large workload.
Both types of grace periods apply only to initial QA sample cases. In a high-impact
grace period, we remove all grace period cases from performance accuracy calculations.
In a low-impact grace period, we include all grace period cases with a group I deficiency
in calculating performance accuracy, but we count them as deficiency-free cases. The
Office of Quality Review (OQR) determines which type of grace period to establish.
For a detailed description of the two types of grace periods, see DI 30005.115C.1. and DI 30005.115C.2. in this section.
1. High-impact grace period
When we expect a new, revised, or clarified policy or procedure to affect a large
workload, e.g., when there has been a major revision to one of the widely applied
listings, we exclude all grace period cases from performance accuracy statistics and
do not report them in the normal QA process. Instead, we track grace period cases
separately, and maintain separate data. We augment the initial QA sample to replace
the grace period cases to maintain statistical precision in the reported accuracy
For additional information on sample augmentation, see GN 04440.123D.4.
2. Low-impact grace period
When we do not expect a new, revised, or clarified policy or procedure to affect a
large workload, we do not exclude grace period cases from adjudicating component performance
accuracy statistics. However, we treat initial QA cases that fall under the grace
period and contain a group I deficiency as deficiency-free cases for performance accuracy
calculations. We apply the grace period only to initial QA cases.

see GN 04440.123D. and GN 04440.123E.
