There is no such general rule Whether something requires an Action to do and whether a successful check is necessary to do it are completely separate questions. There is no rule stating that if you have to roll an ability check, doing so also consumes your Action.
How is an ability check calculated?
To make an ability check, roll a d20 and add the relevant ability modifier. As with other d20 rolls, apply bonuses and penalties, and compare the total to the DC. If the total equals or exceeds the DC, the ability check is a success—the creature overcomes the Challenge at hand.
Can you critically fail an ability check?
By the rules as written, is is not – the “critical fail” and “critical hit” rules are applied to attack rolls and death saving throws, but not to ability checks.
Do you add proficiency to ability checks?
In either case, proficiency in a skill means an individual can add his or her proficiency bonus to ability checks that involve that skill. Without proficiency in the skill, the individual makes a normal ability check.
Is a 20 always a hit?
Automatic hit/success In several editions of the D&D rules, a natural 20 is an automatic hit on an attack roll, regardless of the opponent’s armor class. Contrary to popular belief, a natural 20 is not an automatic success on skill checks or ability checks in D&D 3rd, 4th, or 5th edition.
What is rolling a 1 in DND?
It’s a house rule. By rules, the only effect of rolling a 1 is that it’s an automatic miss on an attack roll. There are no other effects on attacks, and a 1 isn’t necessarily a fail on anything other than an attack roll.
When do ability checks require a full action?
Unambiguous cases are spelled out in the section on Actions in Combat (PHB, p. 192-193). For example, the “Hide” or “Search” actions both require ability checks, and both take up your Action (unless you have a special feature which allows you to do them some other way). However, not every ability check in combat requires your full Action.

An ability check tests a character’s or monster’s innate talent and training in an effort to overcome a challenge.
