Using the sample pool, SFAs will calculate the required sample size (number of applications that must be verified) using one of the following methods:

- Error Prone (Standard) Sampling Method
- Random Sampling Method (Alternate 1)
- Focused Sampling Method (Alternate 2)

**The Error Prone (Standard) Sampling Method must be used by an SFA unless it qualifies to use one of the alternate sampling methods.** The SFAs approved to use an alternate sampling method are listed in the SFAs Required to Conduct Income Verification tab.

When determining the sample size, regardless of the verification method used, SFAs must **always round up to the nearest whole number**. For example, if your sample size is 3.18 you must verify **4 **applications. **You may not verify any more or any less than the required sample size allowed.** Please note, at least one application must always be verified.
