Which of the following is NOT a component of the Informal Reading Inventory?

The correct response highlights that a standardized achievement test is not a component of the Informal Reading Inventory (IRI). An IRI is typically used to assess a student's reading level and to identify specific reading strengths and weaknesses in a flexible and informal manner.

The components of an IRI usually include assessments such as phonemic awareness tests, which evaluate a student's ability to hear and manipulate sounds in words; word recognition lists, which gauge a student's ability to recognize high-frequency words; and graded reading passages that measure comprehension and fluency across various text levels.

In contrast, a standardized achievement test is designed to measure a student’s performance against a consistent standard across a broad population, rather than focusing on individualized reading skills or strategies. This fundamental difference in purpose distinguishes standardized tests from the personalized assessments found in an IRI, thereby confirming that a standardized achievement test does not belong as an element of an Informal Reading Inventory.
