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, Grade 8 Science Combined National and State Main Assessment, by Item and Block: 2009

NAEP Technical DocumentationRange of response codes, percent agreement, and Cohen's Kappa or intraclass correlation for the constructed-response items used in scaling, grade 8 science combined national and state main assessment, by item and block: 2009
Block Item Range of response codes Sample size Percent agreement Cohen’s Kappa Intraclass correlation
— Not available. 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.
