NWEA College Readiness Linking Study 


The RIT Scale is a curriculum scale that uses individual item difficulty values to estimate student achievement. An advantage of the RIT scale is that it can relate the numbers on the scale directly to the difficulty of items on the tests. In addition, the RIT scale is an equal interval scale. Equal interval means that the difference between scores is the same regardless of whether a student is at the top, bottom, or middle of the RIT scale, and it has the same meaning regardless of grade level. 

  • Characteristics of the RIT Scale include:
It is an achievement scale.
It is an accurate scale.
It is an equal interval scale.
It helps to measure growth over time.
It has the same meaning regardless of grade or age of the student.

Parent Resources

  • Information about my child's NWEA Assessments
The NWEA Parent Toolkit was created as a resource and guide for parents. It includes Frequently Asked Questions, Tips for Parents, and a list of web sites for parents and kids. We hope you find this toolkit helpful and invite you to have conversations with your school district personnel about NWEA's assessment tools. 
  • What is a Lexile Score?

With Lexile range scores educators and parents can:

    • Identify a student's individual reading level.
    • Match a learner's reading level with fiction, non-fiction, and instructional materials spanning thousands of books and millions of articles. 
    • Track a student's reading comprehension over time and set goals accordingly.
    • Forecast whether a reader will be able to easily comprehend the material.
    • Set and track goals for independent reading.
    • Plan for disparities between student reading comprehension levels and the readability of assigned materials.
    • Easily create customized reading lists for individual students.
    • The NWEA College Readiness Linking Study examines the predictive relationship between students' RIT scores on MAP® assessments and the college readiness benchmarks of the EXPLORE®, PLAN®, and ACT® achievement tests. Using the results of this study, educators can predict performance on these assessments' reading, English or math tests based on students' corresponding MAP scores in reading, language usage, and general math.
