This review of methods for validating writing assessments was conceptualized within a framework suggested by S. Messick (1989) that included five operational components of construct validation: (1) content representativeness; (2) structural fidelity; (3) nomological validity; (4) criterion-related validity; and (5) nomothetic span.

A study with more than 1,000 students in grades 3 and 8 explored the advantages of analytical scoring in writing assessment. Cluster analysis revealed 11 patterns of student scores, reflecting different patterns of writing strength and weakness, and replicated across 5 modes of writing. (SLD)
