What is the difference between “competence” and “skill”?

Competence is specific required skills to perform a job, which we say it as proficiency.  Skill can be any type of ability/know-how,  that a person has.  An Accountant may has skill to work in HR, but to reach its actual competency, he/she should go for further education and training.

A Skill is learnt.

Competence is the ability to deliver successfully.

You can be competent without being skillful (natural ability).

In modern society & business we seem to have forgotton that and assume that if people have the skill it means they are competent.

Skill: is innate and can be the product of personal development 

Efficiency: is one measure of the performance of the business over the chart: the extent of investigator

I think they have the same target competence means ability or qualification and skills is also ability but skill is deeply focusing in a specific field.

Competence is something you display as you dispense of your duties while a skill(s) is what you possess.

Competence is a 'Present Ability' to perform the 'task at hand' .. Skill is an ability that one possess but need not necessarily be needed or capable of the task at hand.

Skill is ability and capacity acquired through deliberate, systematic, and sustained effort to smoothly and adaptively carry out complex activities or job functions involving ideas

A competency is more than just knowledge and skills.  It involves the ability to meet complex demands, by drawing on and mobilising psychosocial resources (including skills and attitudes) in a particular context. 

Competence is knowing your stuff and Skill is developed practicing and applying it correctly to real live situation

What I think is as below:

Competence is a refined sturcture of skill & may be defined as various derivates. Without having skills we cannot be a person of competence.

Basically to acquire knowledge of something is can be described as SKILL & making that knowledge is Competence.

Skill is something that comes after training and competancy is something thats comes after learing or skill is some thing tangible and competance is something intangible.
