Happy Home Academy

The Happy Home Academy (HHA), known as the Happy Room Academy (HRA) prior to, is a housing association in the that evaluates and scores the player's house. The house is scored based on the items placed in the players house, with certain types of items worth more than others, and some offering point bonuses. When the HHA evaluates the player's home, it sends the player a letter containing their score and advice on how to improve it; if the player reaches certain score thresholds, the HHA will send them unique items.

In games prior to, the Happy Home Academy is unseen, but in , it appears as a building operated by Lyle; Lyle also runs the HHA in from within Nook's Homes.

Additionally, some bonuses and deductions are only available on the main floor.

On each Sunday, the HRA sends the player their evaluation results through the mail. The player can speak to Lyle at the HRA building to view their score at any time, and they can ask to stop receiving weekly letters.

At the back of the HRA is the model room (a room theme chosen by Lyle every month that satisfies a certain theme). If no room fits the theme for the month, there will be no model room, and the area for the model room is replaced by an empty 4x4 room with a concrete wall and floor.

In, the Happy Room Academy has been renamed to the Happy Home Academy and is now located inside Nook's Homes. It is still run by Lyle, and it functions in a similar way as it does in, but there is no model room. Instead, when all rooms in the player's house have been built, they may accept a theme challenge, where they can choose one of eight themes to have their house graded on. Every item and exterior house part is part of one or more of the following eight themes: Antique, Fairy Tale, Harmonious, Quirky, Rustic, Sci-Fi, Toy Shop, or Trendy. The player can receive point bonuses if their house has many items and exterior parts of the chosen theme.

Lucky bonuses have changed, and now include villager pictures of residents currently living in town. There is no complete theme bonus in, and the Happy Home Academy does not rate the player's basement.

In, after upgrading the player's tent to a house, Tom Nook informs them that all homeowners are automatically registered in the Happy Home Academy, which will send regular evaluations and advice. The HHA has no physical presence on the player's island, but instead it sends an evaluation by mail most Sunday mornings, which cannot be disabled, as well as congratulatory gifts when the player upgrades their house. 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.

Trivia

 * The music from the Happy Room Academy building in is reused on a TV talk show in, albeit in a slower tempo.
 * In, cranky villagers will sometimes say that the Happy Room Academy once judged their "great-grandpa's" home. This implies that the HRA has been around for a long time.
