Reporting Quantile Student Measures for Students and Materials
Quantile measures for students and materials are reported as a number followed by a capital “Q.” There is no space between the measure and the “Q” and measures of one thousand or greater are reported without a comma (e.g., 1050Q). All student Quantile measures are rounded to the nearest 5Q to avoid overinterpretation of the measures.
 A computed Quantile measure is 772, it should be reported as 770Q.
 A computed Quantile measure is 777, it should be reported as 775Q.
The measures that are reported for an individual student should reflect the purpose for which they will be used. If the purpose is accountability (at the student, school, or district level), then actual measures should be reported at all score points. If the purpose is instructional, then the scores should be capped at the upper bound of measurement error (e.g., at the 90th percentile point). In an instructional environment where the purpose of the Quantile measure is to appropriately match learners with math material, no student should receive a negative measure. Therefore Quantile measures of 0Q or below are reported as “EM” for “Emerging Mathematician.”

Some assessments report a Quantile range of 50Q above and 50Q below the student’s actual Quantile measure. The Quantile range takes into account any measurement error found in the tests and the Quantile measures of the skills/concepts. If a student attempts material above his or her Quantile range, the level of challenge may be too great for the student to be able to construct an understanding of the skill or concept. Likewise, the material below the student’s Quantile range may provide the student with little challenge.
All Quantile measures for mathematics materials are rounded to the nearest 10Q. Measures range from below 0Q (e.g., EM50Q) for beginning mathematics materials to above 1600Q for advanced materials. For materials with Quantile measures below 0Q, the negative sign is replaced with an “EM” code indicating that these are “Emerging Mathematics” materials.
