What percentage of understanding is typical for performance at the instructional level in an informal reading inventory?

The percentage of understanding that is typically considered acceptable for performance at the instructional level in an informal reading inventory is within the range of 60-70%. This level indicates that a student has a reasonable grasp of the material, making it suitable for instruction to enhance their reading skills further.

At this level of comprehension, students demonstrate enough understanding to receive support and improve their literacy without feeling overwhelmed. Instruction can be tailored to fit their needs, aiming to move them toward higher levels of proficiency. Achieving this range allows educators to determine the appropriate instructional strategies to build on students' current abilities while providing the necessary challenges to facilitate growth. Other percentages, such as 80% or 90%, might indicate a higher level of mastery that may be more suitable for independent reading rather than instructional purposes.
