KUSD provides MAP (Measure of Academic Progress) testing in grades K-8. These assessments cover Math and Reading, and are given during a Fall, Winter, and Spring testing window. Each school sets their specific testing dates within these windows. These tests present students with engaging, age-appropriate content. As a student responds to questions, the test responds to the student, adjusting up or down in difficulty. The RIT score and the percentile for each test will be available in Infinite Campus after each completed testing window. Please review the MAP Parent Toolkit for further explanations.
Percentiles are used to compare one student’s performance to that of the norm (average) group. Percentile means the student scored as well as, or better than, that percent of students taking the test in his/her grade. There is about a 68 percent chance that a student’s percentile ranking would fall within this range if the student tested again relatively soon.
This number indicates the percentage of students in the NWEA norm (average) group for this grade that this student’s score equaled or exceeded.
The percentile rank is a normative statistic that indicates how well a student performed in comparison to the students in the norm group. A student’s percentile rank indicates that the student scored as well as, or better than, the percent of students in the norm group. In other words, a student with a percentile rank of 72 scored as well as, or better than 72 percent of the students in the norm group.
Tests developed by NWEA use a scale called RIT to measure student achievement and growth. RIT stands for Rasch UnIT, which is a measurement scale developed to simplify the interpretation of test scores. The RIT score relates directly to the curriculum scale in each subject area. It is an equal-interval scale, like feet and inches, so scores can be added together to calculate accurate class or school averages. RIT scores range from about 100 to 300. Students typically start at the 180 to 200 level in the third grade and progress to the 220 to 260 level by high school. RIT scores make it possible to follow a student’s educational growth from year to year.
Records are sampled from between 3.6 and 5.5 million test scores from 500,000 to 700,000 students attending over 24,500 public schools in 5,800 districts spread across all 50 states.
