# Quantile® Measures

Quantile measures 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 over interpretation of the measures. If the Quantile measure is xxx2.5 or higher or xxx7.5 or higher, it is rounded up to the next highest 5Q. For example if
• a computed Quantile measure is 772.51, it should be reported as 775Q
• he computed Quantile measure is 777.42, it should be reported as 775Q
Measures that are at or below 0 should have the leading negative sign replaced with “EM” to signify that the measure represents an “Emerging Mathematician”. For example, a measure of -100Q would be reported as EM100Q. As with any test score, uncertainty in the form of measurement error is present; if uncertainties (i.e. numeric representations of measurement precision) are to be reported, the values should be rounded to the nearest whole number and include a trailing “Q” after the number (e.g., 90Q, 114Q). For additional information please see the MetaMetrics, Inc. Marketing and Branding Guidelines document.

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.”
