What is the minimum number of methods of verification required for STG membership verification?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (B)

Verification of STG membership relies on corroborating evidence from multiple sources to ensure accuracy. Requiring at least three distinct methods of verification means no single report or observation alone can decide membership, providing redundancy and a clearer, more reliable picture.

Think of it as gathering different kinds of evidence that point to the same conclusion: the inmate’s own admission, observed behavior or affiliations by staff, and corroborating information from other sources (such as additional staff, other inmates, or official documents). When three independent indicators align, the case is much more solid than if only two or a single source were used.

Two indicators can be insufficient because they might reflect a misinterpretation or isolated incidents. Adding a third method strengthens the basis for the determination, making the conclusion more trustworthy. That’s why three methods are considered the minimum.
