FAQs

What is the intended purpose of the CASAS math assessments described in the manual?

The manual states the test’s intended purpose and explains how examinees’ responses allow them to demonstrate skills associated with the NRS educational functioning levels.

How does the manual address test development and pilot/field testing?

It documents the nature of examinee samples used during pilot or field testing, the number of examinees per item, how samples matched the target adult education population, and steps taken to maintain examinee motivation.

How are content validity and score matching to NRS levels established?

The manual describes procedures for content validity, including expert judgments linking items to NRS functioning levels. It also explains score matching by documenting standard-setting procedures that transform raw/scale scores into estimates of NRS educational functioning levels and provides standard error information.
