Abstract: Core competencies of a participant, such as an employee, is assessed using a competency assessment tool. A developer defines core competencies for any of a variety of topics and develops questions and demonstrative tasks for respective learning objectives under the core competencies. Participants, in turn, perform the demonstrative tasks that are evaluated by an observer and provide responds to the questions. A score is calculated based on the evaluation and response to determine how well the participant exhibits the learning objectives and the competency of the participant is assessed, which is communicated to the participant. A  recommendation is made to an administrator to create a development plan when the participant's score falls below a predetermined threshold. In certain embodiments, the participant is a subject matter expert that validates a nexus between the learning objectives and the questions and demonstrative tasks.
