Competency Based Learning is a form of learning that focuses on mastering one skill at a time before moving to the next, more advanced skill.
For example, in a drawing course, students may need to learn basic Adobe Illustrator shapes before learning how to create custom ad-hoc shapes on their own.
This method empowers students by focusing on individual skill mastery. There is less pressure to learn quickly because student success is measured by individual proficiencies. This approach might be good if you are teaching a very complex skill.
