Notes: *SAs that did not reach the benchmark. (a) 18 samples instead of the usual 19 were obtained; the decision rule is unchanged. (b): Due to insecurity, samples were not taken from SA2 in the May 2010 round of LQAS. (c) 17 samples instead of the usual 19 were obtained; the new decisiosn rule is 8. (d) 20 samples instead of the usual 19 were obtained; the new decision rule is 11. (e) 12 instead of the usual 19 were obtained; the new decision rule is 7. (f) 17 samples instead of the usual 19 were obtained; the new decision rule is 9. (g) 20 samples instead of the usual 19 were obtained; the new decision rule is 20. (h) 12 samples instead of the usual 19 were obtained; the new decision rule is 9
