It is possible to not receive an HHA evaluation some Sundays.

The HHA assigns the player a rank based on their score: either B, A, or S. The point requirement for each rank increases with each house expansion. The player will receive the Decorated Decorator Nook Miles achievement worth 1,000 miles after obtaining an S ranking.
