Why do some of my students have a drop in RIT score when they switch from MAP Growth K-2 to MAP Growth 2-5 tests?
Audio supportSome students who are not independent readers may have a higher score in the K-2 test because it contains audio support. When taking the K-2 test, students don’t need to labor over decoding at all – they can just show what they know in relation to the skill being assessed.
Another factor is that MAP Growth K-2 and MAP Growth 2-5 tests have different formats and content coverage. Second grade students taking the 2-5 tests can see content that they may not have been exposed to yet. For example, they may not have had exposure to long division, or some of the vocabulary in the 2-5 reading test. This may explain a one-time drop in score. If the student is performing close to grade level, we would recommend having the student take the 2-5 tests, but would suggest interpreting the growth scores carefully.
Difference in content and higher grade level content
If a student has tested in both K-2 and 2-5, you can consider the standard error of measure (SEM) for each test score. A lower SEM indicates a more precise score within the content being assessed. We also recommend considering other measures, such as classroom performance and performance on other assessments.
Which test score is more accurate?
The RIT between the two tests (K-2 and 2-5) should correlate. When they do not, it is often because the content being assessed does not match the content being taught. As a general rule, the student should be tested according to the content they are being taught. If the student is being instructed on 3rd grade level content, they should be assessed with a 2-5 test. As noted above, reading ability matters for both the reading and math tests, since there is no audio in the 2-5 test.
Are the K-2 and 2-5 tests on the same RIT scale? Which assessment should I administer?
