This is the first book to present a practical, problem-solving approach and hands-on tools and techniques for assessing English-language learners and culturally diverse students in K-12 settings. It meets a crucial need among practitioners and special educators working in today's schools. Provided are research-based, step-by-step procedures for conducting effective interviews with students, parents, and teachers; making the best use of interpreters; addressing special issues in the prereferral process; and conducting accurate, unbiased assessments of academic achievement, intellectual functioning, language proficiency, and acculturation.
