Where To Find the IV Judge + How To Check IVs (Pokémon Platinum)

The IV Judge in the Battle Tower (Pokémon Platinum)

The IV Judge (also known as the IV Checker or Stats Judge) is an NPC in the Pokémon series who can measure a Pokémon’s Individual Values, or IVs.

In Pokémon Platinum, the IV Judge can be found in the lobby of the Battle Frontier’s Battle Tower. This means you’ll only be able to check your Pokémon’s IVs in the post-game after you’ve defeated the Pokémon League and entered the Hall of Fame.

What IVs Are + How To Measure Them

The Individual Values of a Pokémon are like its DNA: fixed genetic blueprints that are partly responsible for a Pokémon’s potential strengths and weaknesses.

There is one IV for each stat, each with a value range from 0 to 31:

  • HP
  • Attack
  • Defense
  • Special Attack
  • Special Defense
  • Speed

Besides helping to determine a Pokémon’s strength, IVs are also instrumental in Pokémon Breeding.

When two Pokémon produce an Egg, three of the parents’ IVs are passed to the baby at random. If you’re committed to breeding an exceptionally powerful Pokémon, you can exploit this information to great effect.

A Pokémon’s IVs also play an important role in determining its Hidden Power type.

IVs are completely hidden from you for the majority of the game. But after you’ve completed the main story, you can speak to the IV Judge for coded hints about the direction your Pokémon’s IVs are leaning.

The IV Judge won’t give you hard numbers about your Pokémon’s IVs.

But he will give you a much better idea of where your Pokémon’s strengths and weaknesses lie.

This is indispensable information if you’re trying to build the strongest team possible.

Finding the IV Judge

You can find the IV Judge at the Battle Tower, which is a facility in the Battle Frontier. This means you won’t have access to him until after you’ve defeated the Pokémon League.

To find the IV Judge, start by Flying to the Fight Area and head northeast into the Battle Frontier building.

How To Check Your Pokémon’s IVs

Speak to the IV Checker and he will offer to appraise the potential of your Pokémon.

The IV Judge will describe your Pokémon in what sounds like vague phrasing. However, you can interpret his words to get a fuller understanding of your Pokémon’s IVs.

Decoding the IV Judge’s Statements

His first statement is about the chosen Pokémon’s overall IVs, as described below:

Pokémon’s Overall Potential
Appraisal Total IVs Average IV
“decent” 0 to 90 7.5
“above average” 91 to 120 17.5
“relatively superior” 121 to 150 22.5
“outstanding” 151 to 186 28

The IV Judge’s next two statements will describe your Pokémon’s best stat. This stat will have a higher IV than the rest.

Note: If more than one IV is tied for the highest value, the IV Judge will name only one of them.

And then finally, the IV Judge will describe just how high the Pokémon’s best stat’s IV is.

Although you won’t be given an exact number, you can figure out a general range of this IV based on the language the IV Judge uses to describe it:

Highest IV Stat
Appraisal IV Stat Range
“rather decent” 0 to 15
“very good” 16 to 26
“fantastic” 26 to 30
“can’t be better” 31

In the example above, it’s revealed that Banette’s total IVs equal between 91 and 120, with the average IV being 17.5.

We also know Banette’s greatest strength is its Special Attack, with a Special Attack IV stat between 26 and 30.

This information can be used when determining Banette’s strengths and weaknesses for breeding purposes, as well as training for battle both in-game and competitively.
