This document discusses factors that affect the assessment of reading. It addresses how reading comprehension involves multiple components that depend on the format of materials and how understanding is assessed. Two key factors discussed are isolating reading strategies and skills for testing purposes, and making the internal reading process more observable. The document proposes two protocols, writing down thoughts and speaking aloud, to help externalize the silent, internal process. It also examines question types like textually explicit, implicit and script-based questions.
