What is the process of validating that previous data and assumptions remain true or have changed?

• A. Initial (Routine) Assessment
• B. Special Assessment
• C. Reassessment
• D. Health Risk Assessment

Answer: (C)

Reassessment is the process of checking whether previous data and assumptions still apply as conditions change. It involves revisiting the baseline information, re-running analyses with updated inputs, and comparing the new results to what was expected. This keeps decisions valid over time, accounting for new measurements, changes in processes or populations, or shifts in environmental conditions. It’s different from an initial assessment, which sets the starting point, and from a special assessment, which is a focused deep dive prompted by specific concerns. A health risk assessment, while important, focuses on estimating health risks rather than re-validating earlier data.
