NAEP Analysis and Scaling → Initial Activities → Constructed-Response Interrater Reliability → Range of Response Codes, Percent Agreement, and Cohen's Kappa or Intraclass Correlation for the Constructed-Response Items Used in Scaling, Age 13 Mathematics Long-Term Trend Assessment, by Item and Block: 2012
| Block | Item | Range of response codes | Sample size | Percent exact agreement |
|---|---|---|---|---|
| NOTE: Special codes assigned to student responses including blank, off-task, and not-scorable were included in the calculation of the percent exact agreement measure.

| † Not applicable. The intraclass correlation is not reported for dichotomously scored items; Cohen's Kappa is not reported for polytomously scored items. NOTE: Cohen's Kappa is a measure of reliability that is appropriate for items that are dichotomously scored. The intraclass correlation coefficient is most appropriate for items with more than two categories. The discrepancy in sample sizes compared to the first table is due to the fact that percent agreement is calculated from the entire sample size, while Cohen's Kappa and intraclass correlation statistics exclude those who omit the item.
