This book investigates the efficacy and implementation of student writing portfolios as a tool for assessment and pedagogical development within diverse classroom environments. Pamela Perfumo and Robert C. Calfee draw upon extensive educational research and practical classroom experience to evaluate how portfolios function as both a diagnostic instrument and a policy mandate. They argue that while portfolios offer a nuanced view of student progress, their success depends heavily on the alignment between institutional policy and the actual practices employed by educators.

Educators and administrators frequently cite this text as a foundational resource for understanding the complexities of alternative assessment models. Experts highlight the authors' balanced approach in addressing both the pedagogical benefits and the administrative burdens inherent in portfolio implementation.
