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). The Lexile scale is like a thermometer, with numbers below zero indicating decreasing reading ability as the number moves away from zero. 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. Above 0L, measures indicate increasing reading ability as the numbers increase. For example, a 200L reader is more advanced than a 150L reader.
Unlike the reader measure, all text measures below 0L are currently reported as BR. MetaMetrics has conducted research to differentiate the BR text measures, and these measures will be available at a later date.
