These workshop materials, meant to accompany the trainer's manual to "Assessment: A Development Guidebook for Teachers of English-Language Learners," consist of individual sheets suitable for making clear transparencies and paper copies as needed for overhead transparencies, workshop participant handouts, and examples of performance-based tasks. The workshop materials help the teacher educator provide teachers of English language learners (ELLs) with information on the six most important aspects of assessment development: proven reform initiatives; content and performance standards; guidelines to consider when assessing ELLs; use of testing accommodations with ELLs; mechanisms that could be used when initially identifying ELLs; and elements to be included in databases for ELLs.
