Item Lexiles

Last Updated: Feb 02, 2021 13:59

What Are Lexiles?

You can add Lexiles to patron and title records for free. However, the Expanded Lexile Services integration allows you to also add multiple Lexile scores for patrons over a period of time, create graphs, and use the Update Title Lexiles utilityContact our Sales Team if you're interested in adding it to your library!

Lexiles have become the most widely accepted reading measurement in use today; renowned as the most accurate way of matching readers to suitable text. Before high school graduation, more than 19 million students will receive a Lexile measurement.

Developed by MetaMetrics, Inc.®, a Lexile is a scientifically-based reading measurement that can be used to match a patron's reading ability to the overall difficulty of a specified text. This provides educators with a standardized system of measurement, allowing them to better monitor the reading progress of their students.

Educators and librarians are also able to better match readers to titles with similar Lexile measurements. In this way, students will be able to have more enjoyable reading experiences and are less likely to become frustrated by unfamiliar vocabulary or complex sentence structures.


How are Lexiles measured?

Using MetaMetrics'® Lexile Analyzer software, titles are measured based on word frequency (semantic difficulty) and sentence length (syntactic complexity); the resulting Lexile value is numeric, rated on a scale between 0 and 2000. Generally, the larger the Lexile measurement, the more complex the sentence structure—as well as the frequency with which difficult words are used.

Additionally, the same Lexile measurement scale can be applied to identify a patron's reading comprehension. A reader's Lexile level indicates that they are expected to have a 75% comprehension score for a title with the same Lexile measurement. For example, a reader who has a Lexile measurement of 840 should be able to comprehend at least 75% of a title that also has a Lexile measurement of 840.


What materials have been Lexiled?

Currently, there are more than 100,000 books and more than 70 million newspapers and magazines articles which have been Lexiled, including some online databases.

Of those 100,000, there are some that can not be properly measured, and are, therefore, given a Lexile code as opposed to a Lexile measurement.

For example, beginning reader materials often have one or two words per page and no discernible sentences; therefore, instead of scoring a 0 or a negative number, they are assigned a Lexile code of BR (beginning reader).

Poetry and screenplays often use unorthodox punctuation and unconventional paragraphs and line-breaks. These make it difficult for the Lexile Analyzer to determine where a sentence begins and ends. Therefore, these are assigned a code of NP (non-prose).


Who uses Lexiles?

Reading Counts®, one of the major study programs, uses Lexiles for student interest levels. Many other programs, however, use Lexiles as their standardized method for measuring reading comprehension.


Reading Counts and Lexiles

If you use Reading Counts and your vendor includes that information in your MARC records, the Lexile information particular to Reading Counts is kept in the 526 tag under subfield _b.

Reading Level is kept in subfield _c and the study program name “Reading Counts” is located in subfield _a. This information can also be found at the Scholastic website, where you can look up titles individually.

It is not recommended that you enter Reading Counts® information unless your school or institution also owns the accompanying tests; patrons who see such information may mistakenly think that they can get Reading Counts® credit for reading that title.


Where can I get Lexile measurements for my titles?

Depending on your vendor, the MARC records that you purchase along with your books may already contain Lexile information. If not, they may become available by simply changing your profile with the vendor or by paying an additional charge.

Lexile information is usually stored in the 521 tag with the _a as the Lexile measurement and _b as the indicator of the Lexile.

You can also get Lexile information manually by searching the Lexile Book Database website. The Lexile Book Database is updated regularly, so if you have an item which lacks a Lexile score and can not be located in the database, be sure to check back frequently. What isn't measured today may be measured tomorrow.

If you have the full text of an item that is not contained in the Lexile Book Database, you can use MetaMetrics'® online Lexile Analyzer to score your item.

However, to help make these processes easier, COMPanion has created a Lexile utility for Alexandria that compares your titles to those contained within the Lexile Book Database. If Lexile measurements are found missing from your titles, they will be added to your data.

For more information about the Alexandria Lexile module, contact your COMPanion sales representative at (800)-347-6439.

Alexandria allows you to import and export item Lexile measurements, regardless if Alexandria's Lexile module has been licensed. Furthermore, even if you're not licensed to use Alexandria's Lexile module, you can apply an item Lexile measurement (0 – 2000) via the Lexile field in the Study Programs tab.


If a Lexile measurement has been applied to an item, and you are licensed to use the Alexandria Lexile module, it will be displayed in the Current Item section of the Circulation window.

As shown in the example below, the item has its Lexile measurement (860) displayed in Current Item pane of the Circulation window.
