Every year on October 1st, CEs that must conduct verification count the number of approved applications to determine the verification pool sample size. Since October 1 is a Sunday, you can count the applications as of Friday (September 29) or Monday (October 2).
Write down the number of approved applications and keep that number to use on the Verification Report. We found last year that the POS systems would update a student's eligibility status if they became directly certified during October. Then when the POS application numbers at the end of October didn't match the number from the beginning of the month. That caused problems with the sample size calculation.
The number of approved applications from October 1st must be reported on the Verification Report -- not the number from the end of the month.
TDA has developed a Sample Size Calculator to help you determine the verification pool size and the interval number for selection. You can find the calculator on TX-UNPS in Download Forms under the applications menu for SNP (SNP-123). Your regional ESC has it and it will be posted on Square Meals on the updated DCDV pages.
Just FYI -- no one who used the Alternate 2 method of verification last year calculated the sample size correctly! Everyone verified too many applications. Use the calculator and make sure you have it correct!
