The organization must first consider whether the assessment will use CDA or CER as the assessment engine for determining the assessment results. The complexity of the assessment contributes to whether CDA or CER should be used. CDA can be applied to straightforward assessments with outcome-level scoring and answers that don't require interpretation. CER can be applied to complex assessments that require interpretation of answers, such as comparison of ages, dates, or calculations.
Once the assessment engine, CDA or CER, is decided upon for the assessment, the CDA or CER assessment configuration can be defined.
To create a CDA assessment configuration, a questionnaire and matrix are required. A questionnaire associates an IEG script with a datastore. A decision matrix allows the user to define the logic to achieve outcomes. To create a CER assessment configuration, an IEG script and rule set are required.
The following sections describe the steps required to configure both types of assessments.
