Measures of Academic Progress
The Measures of Academic Progress or MAP tests are achievement measures in mathematics, reading, language usage, and science that are delivered to students on the computer. Students view each question on the computer screen, then select an answer using the mouse or the keyboard. Unlike fixed-form paper and pencil tests with a set group of items, the MAP test adjusts to each student’s performance, allowing an appropriate test to be developed for that student. Because of this technology, the MAP testing system is able to accommodate and accurately assess students at a variety of achievement levels.
MAP RIT Scale
After each MAP test, students receive a RIT score. Think of the score as a student’s height. The score reflects the student’s academic knowledge, skills, and abilities like inches reflect height. The RIT (Rasch Unit) scale is a stable, equal-interval scale, like feet and inches. Equal-interval means that a change of 10 RIT points indicates the same thing regardless of whether a student is at the top, bottom, or middle of the scale, and a RIT score has the same meaning regardless of grade level or age of the student. Scores over time can be compared to tell how much growth a student has made, similar to measuring height with a ruler.
MAP assessments use the RIT scale to create a grade-independent RIT score, which indicates the level of question difficulty a given student is capable of answering correctly about 50% of the time. RIT scores help educators understand what every child is ready to learn. MAP tests produce scores that make it possible to monitor student growth from year to year.
