# MAP Class Reports: The Basics

## MAP Class Reports

When: Immediately

What: Student scores and summary data for your class

## Class Reports: Ways to Use Them

• Observe the range of RIT scores
• Identify strengths and areas of concern
• Consider standard deviation when planning instruction
• Compare class performance to NWEA norms

What is a RIT score?

RIT stands for Rasch unIT, which is a unit of measure that uses individual item difficulty values to estimate student achievement. RIT scores create 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; it has the same meaning regardless of grade level.

The RIT scale is used to measure how "tall" a student is on the curriculum scale and scores can be compared to tell how much growth a student has made, similar to measuring height on a yard-stick. It is important to remember that the RIT score is one of the most important pieces of information on the whole report. This score is independent of the age or grade of the student, and reflects the instructional level at which the student is currently performing.

Why are there score ranges? How should I use them?

It is very important to remember that scores from any test are estimates of performance. No score should ever be treated as absolute. Score ranges indicate the range of measurement error around a particular score (score ranges include one standard error above and below the RIT score). We would expect that if a student took the test again relatively soon, his or her score would fall within this range most of the time. Students performing within the same score range have similar instructional needs.

Any time a placement decision is being made for a student, the score range rather than a single RIT score should be used to help make the determination of whether the student falls above or below established criteria.

## Use your class report to take a quiz to check your understanding!

Use your class report to take a quiz to check your understanding.

1. Which student has the highest score? Where is this child performing related to the norms?
2. Which student has the median score? Where is this child performing related to the norms?
3. In looking at the goal performance, identify areas your class performed well. Are there any trends within your class?
4. Get with your grade level team and compare results. How can you best arrange yourselves to create growth for all students?
