Lexiles & SRI


ESUSD students are assessed using Scholastic Reading Inventory (SRI) - a research-based, computer-adaptive reading assessment program for students in Grades K–12 that measures reading comprehension on the Lexile Framework® for Reading. The most powerful feature of the SRI is its ability to administer fast and reliable low-stakes assessment to inform instruction and make accurate placement recommendations. Aligned to state tests, SRI helps educators forecast student achievement to those important goals.  SRI has undergone extensive studies and been proven to be an accurate indicator of performance on end-of-year state tests.

SRI is an effective assessment to:

•          Identify struggling readers.

•          Apply as a universal screener and progress monitoring tool.

•          Monitor progress toward AYP goals.

•          Monitor effectiveness of instruction.

•          Establish obtainable and realistic growth goals for students.

•          Indicate expected performances on state tests.

SRI test items do not require prior knowledge of ideas outside the passage, do not test on vocabulary taken out of context, and do not require formal logic. SRI derives its question bank from authentic passages of literature that students encounter both in and out of school. Test items are drawn from a variety of content areas.

The Lexile Framework for Reading is an approach to measuring text and reading ability, putting both texts and readers on the same scale to accurately match readers with reading materials or help give an idea of how well a reader will comprehend a text.  A Lexile measure is the most widely adopted reading metric.  Each year, tens of millions of students receive Lexile measures, and there are currently Lexile measures for more than 100,000 books and 80 million articles.

There are two kinds of Lexile measures: the Lexile reader measure and the Lexile text measure. Students receive a Lexile reader measure as a score from a reading test (such as SRI) - it describes his or her reading ability.  Books and other texts receive a Lexile text measure from a software tool called the Lexile Analyzer - it describes the book's reading demand or difficulty. 

The Lexile measure is shown as a number with an "L" after it — 880L is 880 Lexile. Higher Lexile measures represent a higher level of reading ability. The Lexile scale ranges from beginning readers (BR) and beginning-reading text (200L and below) to above 1600L for advanced readers and text. The first "Harry Potter" book, for example, measures 880L.

A student’s Lexile measure is set at the level of text the student can be expected to read with 75% comprehension.  It corresponds to an instructional reading level for the student – not too difficult to be frustrating, but difficult enough to encourage reading progress.

WHY USE LEXILES? Lexile helps readers grow, and helps parents and teachers know!

·         A helpful feature of the Lexile scale is that it is a developmental scale. This means it can be used to show whether a reader’s reading ability is growing (or developing) over time. ESUSD students in grades 3-5 are assessed at the minimum 3 times over the school year.  If a student’s reading growth is too slow, or even stalled, it may be necessary to provide supplemental reading instruction.

·         Lexile measures can be used to both promote reading progress and to assign the right level of reading materials that can help improve student reading ability.  If we know how well a student can read and how hard a specific book is to comprehend, we can predict how well that student will likely understand the book. For example, if a reader has a Lexile measure of 600L, the reader will be forecasted to comprehend approximately 75% of a book with the same Lexile measure (600L). The 75% comprehension rate is called “targeted” reading. This rate is based on independent reading; if the reader receives help, the comprehension rate will increase. The target reading rate is the point at which a reader will comprehend enough to understand the text, but also will face some reading challenges. At this point, a reader is not bored by text that is too easy, but also does not experience too much difficulty in understanding.  The result is a rewarding reading experience. This is the best way to grow as a reader.

·         Lexile measures also provide parents with a powerful tool for connecting children with reading materials at home. Unlike other test results that may simply get posted on the refrigerator or cause parents sleepless nights, Lexile measures offer a way to take action. Families can visit the library or bookstore and use Lexile measures to select leisure-reading materials. In fact, an increasing number of automated library card catalogs include Lexile measures for books and other materials. Experts agree that the best way to build reading ability is practice. Lexile measures provide a way to make that practice meaningful all year round. By reading material at their Lexile level, students can strengthen literacy skills and develop a lifelong love of reading.


When you receive a Lexile measure, try not to focus on the exact number.  Instead, consider a reading range around the number. A person's Lexile range, or reading comprehension "sweet spot," is from 100L below to 50L above his or her reported Lexile measure. Don't be afraid to look at books above and below someone's Lexile range. Just know that a reader might find these books particularly challenging or simple.

In some cases, a reader may not want to choose a book at the 75% forecasted comprehension rate. For example, if a reader is highly motivated or very interested in a book’s topic, the reader may want to choose a book that will be more challenging (less than 75% forecasted comprehension). At other times, the reader may want to choose a book for easy independent reading (90% or higher forecasted comprehension). To adjust the forecasted comprehension rate, simply look for a text that has a different Lexile measure than the reader. If the Lexile text measure is higher than the Lexile reader measure, forecasted comprehension goes down. If the Lexile text measure is lower than the Lexile reader measure, forecasted comprehension goes up.

It is important to note that the Lexile measure of a book refers to its text difficulty only. A Lexile measure does not address the content or quality of the book. Lexile measures are based on two well-established predictors of how difficult a text is to comprehend: word frequency and sentence length. Many other factors affect the relationship between a reader and a book, including its content, the age and interests of the reader, and the design of the actual book. The Lexile measure is a good starting point in your book-selection process, but you should always consider these other factors when making a decision about which book to choose.  Diary of a Wimpy Kid is a 950L - is this a good selection considering your child's level and interests?

To ­find the Lexile measures of books, or to search for books using a Lexile measure or range, go to  Several search options are available, including title, reader interest categories, author and developmental level. Students can also create their own individual book list.
