The Scoring Reliability files contain data that can be used to investigate the reliability of the PIRLS constructed-response item scoring. The Scoring Reliability file contains one record for each booklet that was double scored during the scoring reliability exercise of the free-response items. For each constructed-response item in the achievement test, the following three
variables are included:
• Original Code Variable (achievement item response codes obtained from the first coder)
• Second Code Variable (achievement item response codes obtained from second coder)
• Response Code Agreement Variable (degree of agreement between the two codes).
