Validity: Assessment's Cornerstone, Mastering Assessment: A Self-Service System for Educators, Pamphlet 15

Paperback
The scores students achieve on tests lead teachers to make inferences about these students' knowledge, skills, and affect. But how can teachers know if these inferences are valid? This booklet, Validity: Assessment's Cornerstone, presents three kinds of validity evidence sanctioned by the measurement community, and focuses on the one most relevant to teachers' classroom tests: content-related evidence of validity. The MASTERING ASSESSMENT series is a set of fifteen practical, easy-to-use booklets covering a wide range of topics related to educational assessment and accountability. These groundbreaking booklets put the most relevant information on assessment at teachers' fingertips and provide an important resource for educators looking to learn the ins and outs of becoming assessment literate. Paired with the series' Facilitator's Guide (available for download at no additional charge from Pearson's Instructor Resource Center), Mastering Assessment is the perfect tool for building assessment literacy either in self-study or a professional development program.
