<p> Quantiles Why Quantiles  Link student ability to skill difficulty  Forecast student success rate (after an introductory lesson)  Track growth over time  The state is piloting and may be using quantiles as performance measures in the new assessment system CCSSI-Common Core State Standards Initiative-These are our newest ELA and Math Standards in Kentucky (Science will be coming soon). A Quantile (quantile measure) is the unit of measurement along a developmental scale that locates an individual's ability to think mathematically in a taxonomy of mathematical skills, concepts, and applications. Currently, the scale’s range is for K-12 education (10Q to 1400Q). Quantiles measure student mathematical achievement and concept/application solvability similar to the way Lexiles measure reading ability and text difficulty. A Qtaxon, is a specific mathematical topic, concept or skill (standard). They are quantile specific  The Student Data tool will provide a quantile measure for each student who took a KCCT Math assessment in the Spring of 2010  The Quantiles are Lexiles for Math (kind of) o Lexiles are the current level of performance o Quantiles are the readiness for math instruction  Quantiles range from EM (Emerging), 0 to 1400  Once a student performance level (quantile) is identified, then they should be able to practice and learn skills within 50 quantile  If a student is not ready to experience instruction at the current level, prerequisite skills (Qtaxons) can be back mapped utilizing the “Math Skill Database” *Quantile skills (Qtaxons) can be back mapped . . . which means:</p><p>*Qtaxons are “cross walked” to CCSSI on the web . . . which means: www.quantiles.com</p><p>Quantile Teacher Assistant This link provides examples which relate specifically to core content and Qtaxons (New CCSSI on the way)</p><p>Math Skill Database This link provides for a crosswalk from the CCSSI standards to Qtaxons as well as links to back mapping</p><p>Resources This link provides access to multiple resources, white papers, and other information which can help inform educators and parents on Quantiles.</p><p>Grade Student Measures K-1 EM to 260Q 2 175Q to 405Q 3 375Q to 605Q 4 480Q to 720Q 5 550Q to 815Q 6 645Q to 895Q 7 665Q to 995Q 8 730Q to 1020Q Algebra I * 760Q to 1065Q Geometry * 810Q to 1115Q Algebra II * 890Q to 1240Q</p>
