Psychometric Services

Over 35 million students are receiving Lexile measures from more than 65 popular reading assessments and programs. We can help you report student reading ability as Lexile measures for either an English or Spanish reading assessment in a variety of ways:

  • Conduct a study that demonstrates how your existing reading or writing assessment correlates with the Lexile scale.
  • Develop and implement custom reading assessments that report Lexile measures.
  • Lease your test items to build an assessment that reports Lexile measures. This option is only available for English reading assessments.
