Using the Informal Reading Inventory

The Informal Reading Inventory (IRI) is an individually administered survey designed to help you determine a student's reading instructional needs.

A student's performance on the IRI will help you determine the instructional level and the amount and kind of support the student is likely to need in Invitations to Literacy.

Specifically, the IRI will help you assess a student's strengths and needs in these areas:

The IRI materials consist of a Student Booklet and a Test Manual. They contain word lists and reading selections for these levels of Invitations to Literacy: Levels 1.1-1.3, 1.4-1.5, 2, 3, 4, 5, and 6.

In the Student Booklet, there are two or three reading passages for each level of the inventory. They are excerpts from selections at the same grade level of the reading program.

The Test Manual contains the information and materials you need to administer and score the IRI.

While an IRI is regarded as a suitable tool for determining students' reading abilities and needs, it is not infallible. You should use the information from the IRI and the Baseline Group Tests, along with any other information you have about a student, to make an initial instructional plan. After you have observed the student for two to three weeks, you should have a better idea of the student's reading abilities. Your observations may suggest different strengths and needs. Adjustments should be made as necessary.
