How is the NWEA MAP Test Scored?
What is included in the NWEA MAP Test Score Report?
Grouping: Shows the selection made for optional grouping when the report was requested. Choices are gender, ethnicity, or none (default).
Subject area tested.
Test Type: Test taken, such as S/G (survey with goals).
Growth Measured from shows how your child is doing now, compared to a previous time (if available) the test was taken.
Growth Standard Error: Growth Standard Error (GSE) is an index of the measurement error associated with the change of a student’s scores from one time to another by taking into account the standard error of measurement for each test occasion. A student’s true growth will fall within one GSE of the observed growth about 68% of the time.
Growth Index: RIT points by which the student exceeded the projected RIT (positive values), fell short of the projected RIT (negative value), or met the projected RIT (0) exactly.
The RIT scale is used to chart your student’s academic growth from year to year. Your child’s RIT score is developed when he or she has answered 50 percent of the questions correctly and 50 percent incorrectly, identifies areas of relative strength or weakness and it helps his or her teachers plan for differentiated instruction within curriculum units.
Test RIT: Student’s overall scale score on the current test.
Standard Error of Measurement (SEM): Provides an estimate of the precision of the achievement (RIT) score. The RIT score is accurate within a range of the RIT score plus or minus the SEM. For example, a RIT score of 200 with an SEM of 3 means the RIT score achievement is accurate in the range of 197-203.
Columns and summary statistics are applicable only in Achievement Status and Growth Summary Reports.
Growth Projection: Mean growth observed in the latest NWEA norms study for students who had the same starting RIT score. The values in this column vary with the RIT score. Growth Projection Met: y – yes if the student’s term-to-term growth is equal to or exceeds the growth projection n – no if the growth is less than the growth projection.
Projected RIT: Sum of the current RIT score plus the Growth Projection.
Count of Students with Valid Test Scores: Number of students in the class who have both a valid score and a growth projection.
Mean RIT: Average RIT score of students in the class.
Median RIT: Middle RIT score of this class.
Standard Deviation: Indicates achievement diversity of a group of students. The lower the number, the more students are alike. The higher the number, the greater the diversity in this group.
