What is the difference between analytic and holistic rubrics?

Analytic rubrics score each dimension (content, organisation, mechanics, style) separately then sum for a total. Holistic rubrics give a single overall score based on the best match to a descriptor at each level. Analytic rubrics are better for feedback and inter-rater reliability; holistic rubrics are faster to use once raters are trained.

How do you calculate inter-rater reliability for rubric scoring?

For analytic rubrics with ordinal scales, use weighted Cohen's kappa or ICC(3,1) per dimension. For holistic rubrics, adjacent agreement (raters within 1 point) is often used as a practical threshold: 80–90% adjacent agreement is typical for well-trained raters. Exact agreement for holistic scoring is rarely above 60%.
