The Emergence of an Item-writing Technology

The emerging technology of item writing for achievement tests is reviewed. Several different approaches to item development are discussed. A continuum of item-writing methods is proposed ranging from informal-subjective methods to algorithmic-objective methods. Examples of techniques include objective-based item writing, amplified objectives, item forms, facet design, domain-referenced concept testing, and computerized techniques. Each item-writing technique is critically reviewed, and empirical studies of methods are described. Recommendations for further research and for applications to achievement testing are presented.
