Reasonable assurance is considered a high level of assurance. It indicates that the assurance provider has conducted a thorough and rigorous evaluation, although it does not guarantee absolute certainty. Reasonable assurance is commonly used in auditing and risk management contexts to provide stakeholders with confidence that the organization is operating effectively and complying with relevant standards and regulations.References:
