The material explains how SGPs compare a student’s growth to peers with equivalent prior test scores, then assign a percentile rank based on current-year ordering, without accounting for other achievement drivers. Illustrative scenarios contrast students with the same current score, and results are discussed using regression residual comparisons and correlation evidence. Challenges are highlighted, especially around defining “academic peers.”",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/using-student-growth-percentiles-for-measuring-student-growth-promises-challenges-michigan-school-testing-conference-february-17-2016/504230/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/using-student-growth-percentiles-for-measuring-student-growth-promises-challenges-michigan-school-testing-conference-february-17-2016/504230.png","ImageObject",300,407,{"name":92,"@type":93},"Well Done","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-22","2026-10-03",true,{"@type":102,"interactionType":103,"userInteractionCount":34},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What do Student Growth Percentiles (SGPs) measure and how are they conceptually defined?","Question",{"text":112,"@type":113},"SGPs quantify how an individual student grows over time by describing growth relative to other students with equivalent past test scores.
