These files include SPSS datasets and a Codebook of data gathered from 3 cohorts of 3rd, 4th, and 5th grade students and their teachers on the current state of gender integration in upper elementary school classrooms.</abstract><sumDscr><collDate cycle="P1" event="start" date="2018-09">2018-09</collDate><collDate cycle="P1" event="end" date="2022-05">2022-05</collDate></sumDscr></stdyInfo><method><dataColl><sources/></dataColl><anlyInfo/></method><dataAccs><setAvail/><useStmt/><notes type="DVN:TOU" level="dv">&lt;a href="http://creativecommons.org/licenses/by/4.0">CC BY 4.0&lt;/a></notes></dataAccs><othrStdyMat><relPubl><citation><titlStmt><titl>Martin, C.
