Focal Knowledge, Skills & Attributes (KSAs) The primary KSAs targeted by the design pattern.
What we want to make inferences about. Additional KSAs
Other KSAs that may be required for successful performance on the assessment tasks.
Potential Observations & Potential Work Products What students say, do, or make that constitutes the
evidence Characteristic Features and Variable Features
Aspects of assessment situations that are likely to evoke the desired evidence, or that could be varied across tasks.
