The document outlines the process for administering an Informal Reading Inventory (IRI) to assess a student's reading ability and comprehension. The IRI is used to determine independent, instructional, and frustration reading levels without time limits or comparisons to norms. It involves administering word lists and passages orally and silently at increasing levels of difficulty until criteria are met. Analysis of results identifies the student's capacity level and areas for improvement to guide individualized reading instruction.
