Okay, kiddo, you know how mommy and daddy sometimes have to go to work and they have certain skills that help them do their jobs well? Competency commission is like a group of grown-ups who want to make sure that other grown-ups who have jobs that are really important also have the skills they need to do their jobs well.
Just like how you have to learn new things and practice them to get really good at them, adults have to do the same thing when they go to work. The competency commission helps set standards for what skills adults need to have to do their jobs well. They make sure that the people who work in important jobs like doctors, nurses, and teachers have all the knowledge and abilities they need to do their jobs safely and effectively.
The commission also helps make sure that adults who are already working in these jobs keep learning and improving their skills, so they can keep doing their jobs well and keep helping other people feel safe and happy.
