In Fire Emblem: Three Houses, each class that you can become has its own experience bar – separate from unit experience to gain levels, or skill experience to increase your skills.
Each time you attack, are attacked, or heal, the character will gain 2 Class XP, which can be seen at the bottom of the combat results. It can also be tracked when viewing a unit by looking for sprite of the unit’s class among the skill bars – or it can be seen when re-classing a unit.
If you are able to completely fill the Class experience bar, you will gain mastery of the class, and unlock a unique Ability or Combat Art that can then be equipped regardless of if that character re-classes to something else. Sometimes the ability may be otherwise tied to the class, or benefits the character when using similar class types.
For this reason, it can be worth it to stick with a class even when you have new classes that can be attained through certification, but the process will take more time the higher tier of classes, and the more experience will be required.
Note that due to the slow rate of mastery, you can assign a character as an Adjutant – and they will earn class experience when fighting alongside the main character. If on Normal Mode, you can also grind Class Mastery by playing Auxiliary Battles that do not use up Battle Activity Points.
