RIT Scores
RIT (Rasch Unit) scores are:
A measurement scale created by NWEA for their MAP tests
An equal-interval scale, like feet and inches, meaning the difference between scores has the same meaning regardless of where they fall on the scale
Independent of grade level, allowing measurement of a student's academic growth over time
Typically range from about 140 to 300
Key features of RIT scores:
They measure student achievement level and growth over time
The scores are grade-independent, so a third-grader and a fifth-grader can be measured on the same scale
Each subject area (reading, math, etc.) has its own RIT scale
Growth can be tracked between test sessions as the scale remains consistent
Teachers can use RIT scores to:
Identify what students are ready to learn
Match students with appropriate learning materials
Track academic growth over time
Set achievement goals
When a student takes a MAP test:
The test adjusts its questions based on student responses
Each correct answer leads to a harder question
Each incorrect answer leads to an easier question
This adaptive process continues until the student's precise learning level is determined
The final RIT score represents the level where the student is performing
RIT scores are particularly useful because they:
Measure growth over time regardless of grade level
Allow for comparison of student performance across grade levels
Help teachers identify areas where students need support or advancement
Enable setting of individualized learning goals based on current achievement level
