Does the Reading Inventory for Sys 44NG (Lexile)change each time it is given?

I have students that scored in the 200's in August, 400-500's in January and then dropped in April. Should they have dropped or does this just mean they didn't try? Just wondering if the inventory test gets harder each time it is given?

    Students should make gains on the Reading Inventory each time it is given. The Best Practices for the Reading Inventory indicate that if the score drops more than 60L, then that "bad" test should probably be deleted and the test given again.

    (Part 1) As an experienced READ 180 and System 44 teacher who has a great READ 180 coach, let me share what I've learned: After the initial RI assessment, subsequent tests start at each student's most recent Lexile. So your students could potentially receive higher Lexile levels of text if their Lexile scores increase each test administration. Since the test is adaptive, a student will see a higher level text after answering correctly and a lower level text if they answer incorrectly.

    Part 2: However, with System 44 students' performance on the RI, remember that they are still learning to decode and may not show growth on the RI until they reach Series 15+. Any RI growth they have may be based on background knowledge they bring to each text. I had one System 44 student who increased 500 points but still was on Series 7. How? He loves animals, and on that test his first few RI texts were about...animals. Prior knowledge, NOT comprehension, was the cause of the growth.

    Part 3: And the RI does NOT choose the texts based on what the student chooses for their reading interests at the beginning of the assessment, so my animal-loving student was VERY lucky. I joke with my colleagues that someday we're going to read about him in the newspaper as having won big in Vegas or the lottery... :)

    Your coach is absolutely right. A student's Lexile should not drop, but at times there are scores that do not increase from one test to the next due to the Standard Error of Measure (SEM). Because, generally, the largest SEM for the RI is about 60L, the developers use that as the guideline for when to re-test. Dee, Ask Dee at the READ 180 Community
