What is the main purpose of an informal reading inventory?

The main purpose of an informal reading inventory is to determine a student's reading level through graded passages. This assessment tool allows educators to gather information about a student's reading abilities, including fluency, comprehension, and vocabulary knowledge. By using a variety of graded passages, teachers can identify specific levels of challenge suitable for each student, which helps in tailoring instruction to meet individual needs. This process is essential for developing reading strategies and ensuring students are engaged with appropriate texts for their reading proficiency. Informal reading inventories also provide valuable insights into a student's strengths and weaknesses, informing further instructional decisions and interventions.
