The Battle Institute parallels the one found in previous games. The purpose of this building is to test yourself against a variety of Trainers - many much harder than those you'd find in normal in-game play, exhibiting tactics you'd see more commonly in online and official competitions.
Strategy (gasp!) becomes much more important here than probably any area of the in-game experience. Even if you beat the main quest with ease, don't be surprised if you find yourself struggling, especially if you and your opponent are rarely on equal footing.
Before you begin, there are restrictions on the battles paralleling those of the Battle Maison and general competitions.
- **Flat Battles:** All battles will be Flat Battles. That is to say, Pokémon above Level 50 are made to be Level 50: stats and EV growths will be adjusted appropriately. (Moves remain unchanged).
- **Legendary Pokémon:** Most mainstream Legendary Pokémon are **not** allowed: this means you cannot use Mew, Mewtwo, Ho-oh, Lugia, Celebi, Kyogre, Groudon, Rayquaza, Jirachi, Deoxys, Dialga, Palkia, Giratina, Darkrai, Phione, Manaphy, Shaymin, Arceus, Victini, Reshiram, Zekrom, Kyurem, Meloetta, Genesect, Xerneas, Yveltal, and Zygarde.
- **Pseudo-Legendaries:** These Pokémon **are** allowed, per tradition: this means Articuno, Moltres, Zapdos, Entei, Suicune, Raikou, Latias, Latios, Regice, Regirock, Registeel, Rotom, Mesprit, Uxie, Azelf, Regigigas, Cresselia, Heatran, Cobalion, Terrakion, Virizion, Thundurus, Tornadus, Landorus, and Keldeo are allowed to battle.
- **Duplication:** Hold items (beyond having no items) and Pokémon species may not be repeated.
- **Quantities:** For Single Battles, you need three Pokémon. For Double Battles, you use four.
Once you've spoken with the receptionist in the front of the area, between the PC and record-tracking machine, you can choose your team. You will successively fight five Trainers - winning or losing is somewhat irrelevant; the test will continue regardless and your Pokemon will always been healed between bouts.
Your score is mostly based on how many Pokémon you beat, how many of your Pokémon were beaten, how easily you won, how well you counteracted their tactics, and so on and so forth. After having finished, you'll receive a certificate, naming your rank, test type, and score. The scores are below:
|Battle Test Rank||Number of Stars||Point Range|
|Beginning Rank||1||0 - 999|
|Novice Rank||2||1,000 - 1,999|
|Normal Rank||3||2,000 - 2,999|
|Super Rank||4||3,000 - 3,999|
|Hyper Rank||5||4,000 - 4,999|
|Elite Rank||6||5,000 - 5,999|
Additionally, you will receive items and BP for winning.
