Latinos are the fastest growing ethnic minority group in the United States. The U.S. Census Bureau projects that by the year 2050, one in three students attending schools will be Latino. Academically, Latinos are lagging far behind their non-Latino peers. One factor underlying this achievement gap may be the lack of cultural understanding of many teachers toward Latinos and the Latino culture. The primary purpose of the study was to examine the effect of teachers' cultural intelligence (CQ) scores on teachers' perceived academic and behavioral success of Latino students. The researcher examined to what extent a teacher's CQ score using the Expanded Cultural Intelligence Scale (E-CQS) impacts their perceived academic and behavioral expectations of Latino students when compared to Caucasian students. The study also investigated the district's overall teacher CQ score and its impact on the actual academic achievement of Latino students within that school district. The study further investigated domains or subdomains of E-CQS of participants who possess low academic and behavioral expectations for Latino students as compared to teachers who possess high academic and behavioral expectations. The study includes responses from 291 elementary teachers across 27 New Jersey school districts. The research did not find a statistical significance in teachers' CQ score and their perceived expectations of Latinos. The research found there was no statistical significant correlation between teachers' CQ scores and Latino students' actual achievement. Research found teachers with high expectations for Latino students had a significantly higher motivational CQ, intrinsic motivation, self-efficacy to adjust and general knowledge of business than did teachers with low expectations for Latino students.
