Inside the Battle Institute
The Battle Institute (Japanese: トライアルハウス Trial House) is a building just left of the Pokémon Center in Nimbasa City in Generation V and Lumiose City in Generation VI. The Trainers met here are the same ones that battle in the Battle Subway. The player can opt to fight five consecutive mock battles—called the Battle Test—of either Single Battles (requiring three Pokémon) or Double Battles (requiring four Pokémon). When battling, all Pokémon are auto-leveled to 50, whether they were below in level or above. Bag items are not permitted to be used. At the end of the fifth battle, the player is awarded a score and a rank.
In Black 2 and White 2, the Battle Institute can only be accessed after defeating the Elite Four and Champion. If the player tries to access it before that point, an Ace Trainer will exit the institute and block the entrance, telling the player that they must become the Champion before they can enter. Unlike the Battle Subway, the Battle Institute does not require the player to save the game before participating.
Each battle grows in difficulty, starting with pre-evolved Pokémon and potentially fighting legendary Pokémon by the end and the fourth round has players dealing with lots of Pseudo-legendary Pokemon like Salamence. Once the Battle Test begins, there is no quitting; losing one battle means continuing to the next, until all five battles are complete. The 'Run' command acts as a battle forfeit measure for that battle only. If it is not the fifth battle, the player's forfeit will trigger the next battle.
The scoring system is:
Each battle increases the max points that can be earned, meaning the max amounts of points one can earn in the first battle is lower than the max points one can earn in the last. Points are awarded depending on how many battles are won (no points are awarded for lost battles) and how well the player beats the opponent; fainted teammates count against the final score, as does damage taken.
The scoring breakdown is as follows:
- 1000 points per battle won
- 80 points per opposing Pokémon fainted
- 5 points per switch
- 1 point per super-effective attack
- 4 points per opposing attack that is rendered ineffective (either from type immunities, Levitate, or a status attack that the Pokémon is immune to due to its type)
- 2 points per opposing attack that is rendered not very effective
- 30 points if a battle was won with the opposing side taking at least one turn, 15 points if a battle was won without the opposing side taking a turn
- -80 points per Pokémon fainted
- -10 points per turn
- -10 points per ineffective attack against the opponent (on the same basis as the above)
- -2 points per resisted attack against the opponent
- 1 point per percent of HP remaining after each battle
