Achieve3000 measures students' reading abilities using the Lexile® Framework for Reading that was developed by MetaMetrics. The chart below shows the College and Career Readiness Lexile bands by grade. To determine if a student is on track for college and career readiness, look at the row corresponding to the student's grade in school and find the column where the student's Lexile falls. For example, a fifth grade student with a Lexile of 850 is on track for College and Career readiness. However, a sixth grade student with the same Lexile of 850 is not on track but is approaching being on track.
Beginning Reader (BR) is a code given to readers and text that are below 0L on the Lexile scale. In some cases, for readers, a BR code is followed by a number and L (e.g., BR150L). A Lexile reader measure of BR150L indicates that the Lexile measure of the reader is 150 units below 0L. The smaller the number following the BR code, the more advanced the reader is. For example, a BR150L reader is more advanced than a BR200L reader.
