Each Pokémon in Pokémon GO has three IVs, or Individual Values, which determine that particular Pokémon's HP, defence, and attack scores. These are determined at random, and there's no way at present to change a Pokémon's IVs directly.

IVs in Pokémon GO are almost as mysterious as Legendary Pokémon. You know they're there because certain Pokémon perform better in battle than others, and raise the eyebrows of your Team Leader during an appraisal, but they're completely invisible to you.

That is, unless you use one of the readily available IV calculators. These come in a variety of different forms, but all of them have the same function: to give you an accurate reading of your Pokémon's IVs. Generally, the higher the CP of the Pokémon the more accurate the reading. Pair this with an appraisal by your team leader, and you can get a 100% accurate reading.

In this guide, we're going to explain exactly how IVs work in Pokémon GO and how you can check them using an IV calculator.

Pokémon GO IVs Explained

IVs in Pokémon GO stand for Individual Values, and determine your Pokémon's ability in battle. There are three of them: Attack, Defence, and Stamina, and each has a score out of 15. Here's a breakdown of how they work:

Attack Defence Stamina
Determines the damage of your attacks Determines the damage received when attacked Determines your HP

IVs should not be confused with your Pokémon's base stats though. Each species of Pokémon has a set of base stats – Chansey has high Stamina, Flareon high Attack, and Golem high Defence for example – while each individual Pokémon has a set of IVs, which basically determine the potential increase of a stat when levelling up.

To put this simply, a Chansey will always have generally higher HP than most other Pokémon – even if it has a low Stamina IV. That's because its has a high base stamina. Its IV rating, instead, determines how much HP it gains when it powers up.

Now that you understand this system you can start making decisions about the Pokémon you want to use in different situations and the IVs you're comfortable with for said Pokémon. You'll probably want a Pokémon with high base Stamina and a high Stamina IV to sit in gyms, for example, as they'll last much longer. Conversely, you might want a Pokémon with a high base Attack and IVs when attacking gyms.

How To Check A Pokémon's IVs In Pokémon GO

The first stage of checking a Pokémon's IVs is to have them appraised by your Team Leader. To do so, tap on the Pokéball, tap on Pokémon, then on the Pokémon you want appraised. Now, tap the three lines on the bottom right of the screen and hit Appraise.

Your Team Leader will now give you a bunch of cryptic clues as to the Pokémon's IVs. The first set of clues relate to a Pokémon's IV Range, which is the score out of 100 for a Pokémon's potential. A score of 100 means that your Pokémon has a maximum score of 15 for each of its IVs.

This is what those clues mean:

Valor Mystic Instinct IV Range
Overall, your Pokémon simply amazes me! It can accomplish anything! Overall, your Pokémon is a wonder! What a breathtaking Pokémon! Overall, your Pokémon looks like it can really battle with the best of them! 81 - 100%
Overall, your Pokémon is a strong Pokémon. You should be proud! Overall, your Pokémon has certainly caught my attention. Overall, your Pokémon is really strong! 66 - 80%
Overall, your Pokémon is a decent Pokémon. Overall, your Pokémon is above average. Overally, your Pokémon is pretty decent! 51 - 65%
Overall, your Pokémon may not be great in battle, but I still like it! Overall, your Pokémon is not likely to make much headway in battle. Overall, your Pokémon has room for improvement as far as battling goes. 0 - 50%


Your Team Leader will then tell you your Pokémon's highest IV. If a Pokémon has two stats with equally high IVs, the Team Leader will tell you both of them.

Directly following this, the Team Leader will then give you an estimate of how high that IV might be. Here's what they mean:

Valor Mystic Instinct Highest IV Range
I'm blown away by its stats. WOW! Its stats exceed my calculations. It's incredible! Its stats are the best I've ever seen! No doubt about it! 15
It's got excellent stats. How exciting! I am certainly impressed by its stats, I must say. It's stats are really strong! Impressive. 13 - 14
Its stats indicate that in battle, it'll get the job done. Its stats are noticeably trending to the positive. It's definitely got some good stats. Definitely! 8 - 12
It's stats don't point to greatness in battle. Its stats are not out of the norm, in my opinion. Its stats are all right, but kinda basic, as far as I can see. 0 - 7

Unless you clearly have a max IV score of 15 for all three stats, this appraisal system merely gives you a rough estimate of your Pokémon's total IVs. It's a good place to start though, as you sort out the wheat from the chaff. Then you can go on to getting the exact IVs using an IV Calculator if you deem the Pokémon worthy.

How To Check A Pokémon's IVs Using An IV Calculator

An IV Calculator – of which there are many – can give you an accurate reading of your Pokémon's IVs, its level, and the power of its skills. It achieves this by looking at your Trainer Level, the Pokémon's CP (Combat Power), and the amount of Stardust required to power it up.

This provides a rough estimate, which increases in accuracy the higher the level of your Pokémon. You can also combine this with an Appraisal to get a more accurate reading.

IV Calculators, much like cars, come in two different flavours: automatic and manual. Automatics scan a screenshot of your Pokémon and calculate its IVs based on that, while manual requires you to input the information yourself.

The automatic method is not only the fastest but the most foolproof, as getting the IV range in the correct position can be particularly tough. If that's the method you want to go for, you'll need to download an app on your mobile. Here are our favourites:

If you'd rather not download an app on your mobile, these are our favourite manual options you can use in your browser:

Generally, these manual options are pretty straightforward to use. Choose your Pokémon, input its CP, HP, and the Stardust required to power it up – all of which is available while viewing a Pokémon in Pokémon GO. We'd also recommend including the Appraisal results, as these will really help provide a more accurate rating.
