Developing Performance Competencies

Each competency needs to be well defined to ensure the content of the competency assessment is relevant to the skills you are assessing. Vague and inaccurate descriptions can compromise effective assessment. Customised Assessments can help you to get your performance competencies right.
Below is an example of a clear description of one of a number of specific role performance competencies developed by us for one of our customers.

‘Anticipates customers (internal and external) needs, takes ownership of, plus responsibility and accountability for the level of customer satisfaction by establishing productive relationships, answering customers questions concisely, proactively dealing with customers problems and exceeding customers expectations.’

Along with each competency description a set of performance standards are included. These performance standards form the basis for scoring of the candidates’ effectiveness in the competency.

Competency Assessment

Your custom designed, role specific, competency assessment will provide you with invaluable objective data about each participant’s level of knowledge of the performance competencies critical for success in the role.

When a competency assessment is used for selection in conjunction with reference checks and interviews the three sources of information should all indicate more or less the same things (convergence) about the candidate. If however, one source seems to contradict another (divergence) further investigation should be undertaken to uncover possible explanations.


Engaging content matter experts in the development of your critical performance competencies adds reliability and relevance to your competency testing.

Reliability depends primarily on the quality of the competency assessment construction. Each competency assessment is therefore not generic it is custom designed, role specific and focused on determining the level to which the participant comprehends the performance competencies critical for the target role.

Relevance is the degree of correlation between the competency assessment content and the critical elements of the performance competencies being assessed. This approach (referred to as content related validity evidence) is built into the competency assessment by the assessment developers. To create a competency assessment that has content related validity, the developers involve subject matter experts who thoroughly understand both the subject matter of the competency assessment and the specific role to which the competency assessment is to be applied.
