Lexile Measures Now Better Match Beginning Readers to Text

A team of experienced psychometricians, reading researchers and external experts came together to advance the science behind measuring text complexity.

To better encourage and measure reading growth for even the youngest learner, MetaMetrics®, developer of The Lexile® Framework for Reading, today announced new enhancements to its widely adopted leveling system. Now beginning readers will more easily be able to find books that are matched to their skill level, fostering more rapid reading growth.

The Lexile Framework for Reading is a scientific approach to measuring reading ability and the text demand of reading materials. The Lexile Framework involves a scale for measuring both reading ability of an individual and the text complexity of materials he or she encounters. Tens of millions of students worldwide receive Lexile measures to help them choose targeted readings from more than 100 million articles, books and websites that have been measured.

“Considering that our research suggests that a large proportion of growth occurs by the end of third grade , it’s essential that we equip educators and parents with the best tools and means for ensuring student success,” said Malbert Smith III, Ph.D., CEO, president and co-founder of MetaMetrics. “To accomplish this, a team of experienced psychometricians, reading researchers and external experts came together to advance the science behind measuring text complexity. We are thrilled to make our multi-year research available to the educators, parents and education companies.”

Three major enhancements now more precisely match early-reading materials to students. First, the 2000-point Lexile scale was extended to measure students and texts below 0L. Previously, all books measuring below 0L were given a standalone “BR” (Beginning Reader) code. Now, thanks to extensive research, texts with a BR code will also receive a Lexile measure (e.g., BR100L). The addition of a Lexile measure for books below 0L allows for greater differentiation at the beginner level.

Second, materials read in K–2 classrooms are now being measured across more dimensions. Based on input from teachers and reading specialists and through studies on the reading behaviors of young students,…
