Start the Advanced Item Scoring dialog by clicking Transform Advanced Item Scoring. 8 will appear and allow you to score each item. 8 21 Advanced Item Scoring dialog score column. This information tells jMetrik that 1 point is awarded for a response of “A”. Suppose now that option “B” is incorrect. Type “B” (without quotes) in the option column of the next row, and type “0” in the score column of the same row. This information tells jMetrik that a response of “B” is awarded 0 points. Continue with the remaining response options in a similar fashion.
Subject matter experts also review tests to check their alignment with a domain. Score interpretation fails if either the content domain is poorly specified or the test lacks alignment. g. fail, pass, or high pass). Percentage correct scores can be computed directly from examinee responses, but achievement level scores require the use of a standard Test Scalingâ•… 31 setting process to establish the cut scores that demark the boundaries between achievement levels (see Cizek & Bunch, 2007). Standard setting also involves expert judgment about test content and the knowledge and skills of students at each achievement level.
