Applications and Extensions of NAEP Concepts and Technology.

The National Assessment of Educational Progress (NAEP) has consistently pioneered new assessment methods in conjunction with developing the psychometric methodologies underlying them. Several NAEP developments-such as complex matrix item sampling designs, the introduction of performance-based items in large-scale assessments, vertical scaling, and an intelligent computer system that produces unique assessment reports for participating jurisdictions in the NAEP Trial State Assessmentprogram-are presented in this chapter along with a discussion of their extensions and applications to other current and future assessment projects.
