How frequently are third-party testers audited for compliance?

The frequency of audits for third-party testers is typically described as "regularly, with variation by state." This means that the auditing schedule can differ based on state regulations and policies. Some states may require more frequent audits to ensure that testers are complying with the necessary standards and protocols, while others might have a different approach based on their specific oversight needs. This flexibility allows states to adapt their auditing practices based on their unique regulatory environment, the volume of testing, and the level of risk associated with third-party testers in their jurisdiction.

Other options present a fixed or conditional approach to auditing. Monthly audits could be impractical for many states due to resource constraints, and audits taking place every few years might not provide enough oversight to ensure compliance effectively. The idea of auditing only when a complaint is filed would not support a proactive compliance strategy, as it focuses on reactions rather than ongoing assessment and enforcement. Thus, the chosen answer aligns with the understanding that compliance monitoring is essential for maintaining standards and can vary according to the needs and regulations of individual states.
