What percentage of discoloration in the area of a tub is considered a deficiency?

• A. 25%
• B. 50%
• C. 60%
• D. 75%

Answer: (B)

In NSPIRE, there is a specific threshold for when discoloration on a tub becomes a deficiency. If discoloration covers fifty percent or more of the tub area, it is considered a deficiency because it shows substantial staining that affects appearance and sanitation and needs remediation. Smaller discoloration is treated as cosmetic and not counted as a deficiency. So the threshold used to designate a deficiency is fifty percent.
