• The denominators represent the number of total
numerators represent the number of acceptable results.
The
P : Proficient NP: Nonproficient : Not Rated
Performance ratings are based on accumulated results over four rounds
or dust
(one year). A lab's performance in ground paint chips, soil ,
wipes is rated proficient (P), if: 1) three-fourths (7531) or more of the
accumulated results over four rounds are acceptable or 2) for the last
two rounds, all samples are analyzed and the results are 100 y acceptable.
