Administering and Interpreting an Informal Reading Inventory (IRI) Reading Levels John E. McEneaney Oakland University Rochester, MI
IRI Levels Outcomes You should be able to … 1.Describe the criteria used to assign levels. 2.Recognize implausible hypotheses about overall reading levels based on IRI data. 3.Apply criteria in generating plausible hypotheses about overall reading levels based on IRI data. 4.Justify the assignment of levels that are made based on IRI data.
Reading Levels (based on Betts’ criteria) Reading Level Word Recognition Percentage Comprehension Percentage Independent99-100%90-100% Instructional95-98%75-89% Instructional or Frustration 91-94%51-74% Frustration90% or less50% or less WR % = (number of words – miscues)/number of words COMP % = number of questions correct/number of questions
Establishing Levels After administering the IRI … Find the level that is clearly Independent Find the level that is clearly Frustration Examine the levels between your Ind & Fr levels to assess whether one of these should replace your tentative levels. Levels between the final Ind & Fr levels should all be identified as Instructional.
