*Accessible reference and text on a critical topic--testing pervades society, yet students find its core concepts challenging. *Class tested at two universities; the emphasis on conceptual understanding and application promotes critical thinking. *Flexible organization enables researchers and students to review the basics or delve into advanced concepts as needed. *Competing titles are pricey, dated, and not as reader friendly. *Examples and discussions walk readers through critical decisions in the selection, administration, scoring, interpretation, and development of measurement instruments.

*A one-stop shop for SEM and its uses: the first single resource for graduate students and researchers offering broad and deep coverage. *Includes access to data and syntax files (run in different SEM software packages) on the companion website. *Balances conceptual sophistication with accessible writing; moves from the basics through increasingly complex applications. *Hoyle and his contributing authors are a who's who of SEM experts; chapters were vetted by a distinguished advisory board. *Lower price in paper will facilitate course use.
