Competency, defined, is the ability to do something successfully or efficiently. Proficiency is the degree of competence or expertise. This clarification of the two can assist a trainer/instructor when determining how they will measure and/or assess learning objectives in a course of training. While some objectives may only require assessing a specific "Competency" level, some objectives may require a more detailed look at what level of proficiency the student has performed.
Most often, I will set up a Result Schema in Blackboard Learn for a "Go/No-Go" column to measure objectives where I am only assessing the student's competency. For those areas where I need to measure their proficiency in the task, I will add an addition column with a Result Schema to show the level of proficiency performed.
For additional information on how I setup my Results Schemas in Blackboard Learn, please be on the lookout for my blog with the step-by-step instructions of feel free to comment!
