Effort Values

Effort values, or EVs, are points earned by a Mon through battle, vitamins, or other means. EVs raise a Mon's battle stats. A mon can have a total of 510 EVs, with a maximum of 252 in any one stat. When a Mon has reached the maximum number of EVs, the "EV" at the top of the stats summary page will turn red.
Due to effort values, trained Mons are usually stronger than wild Mons, even those of the same level.
== Effort Points ==
Defeated Mons give out 1, 2 or 3 effort points to a particular stat, depending on species. The points given by each Mon can be seen on its website Dex page; the number and color of squares correspond to to the effort points given. However, in battle formats that do not give any experience (such as in the Battle Tower), Mons will not gain any effort points. 
The contribution of EVs to a Mon's stat is calculated by dividing by 4 and disregarding the remainder. At level 100, a Mon's stats will be one stat point higher in a specific stat for every four effort points gained in that stat. Therefore, ignoring natures, you can add 63 points to a stat (at level 100) through EV training.
Mons gain effort points at the same time as experience, so when a Mon levels up mid-battle, the newly gained EVs will be factored into the new stat. Additionally, stats are recalculated at the end of every battle, so EVs gained after a battle that did not result in a level up may still cause the stat to increase. Therefore, Mons can gain EVs from battling even at level 100.
== EV-related Items ==
Various items can be used to increase EV gain or reset EVs. Vitamins and feathers are consumable items that add EVs to a Mon's stats. Similarly, the EV-reducing berries are consumable items which remove EVs from a Mon's stats. Finally, there are several held items which increase EV gain from battle by applying either a multiplier or flat bonus of EVs.

== EV Training ==
The process of intentionally raising your Mon's EVs in specific stats and avoiding others is called EV training. EV training can be done through use of items or battling, or a combination of both.
