North Western Evaluation Association test results include several different scores. The Rasch Unit score, also known as the RIT score, is designed to measure a child's learning over time. The score is not tied to the child's age or grade. The test assesses children in math, reading and language, and gives a score for each area. The testers provide national averages and school district averages along with the child's score, providing context so parents can better understand the numbers.
The "Student Growth" section of the scores is designed to show how much the child's score has improved since the last test. Younger students typically see larger jumps in growth from year to year. As with the RIT score, the testers also provide national averages.
The student's score in the "Student Percentile Range" shows how the student compares against others around the country who are in the same grade and took the same test. A score of 50 is the average, while a score of 80 shows that the student is in the top 20 percent of children who took the test.
The Lexile range indicates the level of books that a child would be comfortable reading independently. The testers assign books a Lexile code based on how difficult they are; books that are rated much lower than the child's rating are easier for him to read than books above his rating.
