As you may know, Seattle Public Schools uses a computer-based test called Measures of Academic Progress (MAP) to provide schools and families with information about student achievement. Schools administer MAP tests in math and reading two or three times a year to many of our students. (The fall MAP test is optional.) Teachers and principals use information from the MAP tests to monitor students’ academic progress and to design their instruction to help every student succeed. You have likely received your student’s MAP scores and percentile in the mail. These scores are also available online, via The Source, the online resource for families and teachers at http://source.seattleschools.org
As part of its ongoing efforts to follow best testing practices, the MAP test’s vendor, Northwest Evaluation Association (NWEA), recently recalibrated the percentile results associated with our students’ MAP scores, to better measure how Seattle students perform relative to students across the nation. This practice of recalibrating percentiles is common in standardized testing, and happens every several years.
The recalibrated percentile rank scores provide a more accurate snapshot of your student’s performance compared with other test-takers, since they are more representative of the national school-age population.
In order for you to be able to see your student’s academic growth over time more accurately, Seattle Public Schools has updated your student’s percentile scores for the past three years to reflect the recalibrated percentiles. You can find the new MAP scores online at The Source at http://source.seattleschools.org. You may notice only a slight change or a very significant change, depending on how your child scored compared to the larger national average of students taking MAP tests.
A student’s MAP results are reported using both percentiles and a RIT score. The RIT score shows what students are ready to learn rather than what they have already mastered, and is used to show a student’s current achievement on a scale that is independent of grade level. This percentile update does not change your child’s RIT score.
The recalibrated percentiles do not change eligibility for advanced learning (Spectrum or APP) students. Original scores from the Spring 2011 MAP test will still be used for eligibility for advanced learning for 2012-13. Next year, eligibility will be based on the recalibrated percentiles. If you have any questions or concerns about the updated percentiles or the MAP test, please contact firstname.lastname@example.org.
