Level: Intermediate Research suggests that 250 words per minute is the target reading speed for fluent second language reading. Reading for Speed and Fluency is a four-book series specifically targeted at developing reading speed and fluency. Ideal for individual or classroom use, the passages are thematically arranged to enable learners to progress through texts within a specific grouping to build on content and vocabulary. Vocabulary is strictly controlled to provide learners practice in reading at an accelerated pace without interference from unfamiliar vocabulary.
