In my opinion, professional competence can be defined as capable of doing the job well which your profession requires. As a teacher, I had to be capable of teaching students the required material in a positive way to enable them to complete tests with good scores, think for themselves, and be ready for the next year with the skills they needed. Education can help prepare a student for their future by giving them opportunities to practice those necessary skills in internships, classroom performances, and demonstrations of the levels of competence in the skill needed. A critical part of professional competence is the ability to think for yourself, to adjust to changing conditions, and to be able to evaluate yourself honestly as to your own competence. Teachers can help you learn how to evaluate your own performance, give you ideas about how to improve, and then allow you to again practice the required skill to the level needed. My opinion is based on 35 years of teaching, 4 years in sales, and many volunteer years with prisoners who need to learn professional competence in a real job.
