Proficiency is an innate modifier all creatures possess, based on their Character Level or Threat Level. Proficiency itself is 1/2 level, rounded up. There is also Expertise (full character level, mimicking Pathfinder 2e's proficiency rules) and Half-Proficiency (1/4 level, rounded up, mimicking traditional proficiency).
Proficiency is used in almost every aspect of the game.
Proficiency, or a Proficiency Bonus, is a scaling statistic that equals half a creature's level. For every odd character level, you round up to the nearest whole. Having it for a certain aspect of the game is called being 'trained in', or 'proficiency in' such (e.g., being

Long Rests.
You will be asked to add this to the result of a roll and, sometimes, another number or two. The table below will give an idea of what is expected with the Proficiency Bonus.

There are two other forms of Proficiency Bonus: Expertise and Half-Proficiency.
Expertise uses your full character level for the value that would use Half-Proficiency. It is primarily used for Skills, but certain features and abilities will add it other things, such as Frenzied Rage for Barbarians.
Half Proficiency is a creature's character level divided by 4 rounded up, or 1/4th their character level. The table below can be used as quick guide for examples.
