TAMIU subpar in the matriculation of its education majors, of which there were some seven hundred graduates between 2009 and 2012. The institution received 2.5 on an 8.0 ranking system, or 1.5 for its elementary program and 1.0 for the secondary studies. TAMIU provides the majority of public school teachers to the two systems in Webb County. The programs were evaluated based on rigor, selectivity, and the level of mentorship provided to prospective educators. TAMIU officials questioned the motive, methodology, and results of the study. University officials released a statement: "TAMIU joins other teacher-training programs from colleges of education across the nation in challenging the accuracy of NCTQ results that incorporate inaccurate data and inherently flawed research methodology." The NCTQ was founded in 2000 by the conservative think tank, the Thomas B. Fordham Institute. TAMIU suggested that the NCTQ favors the dismantling of university teacher education programs with "bargain-basement online programs, some of which are directed by NCTQ surrogates." TAMIU questioned why no NCTQ researcher visited the campus but instead based its evaluation on information sent primarily to the Washington office via emails. The TAMIU program was placed on probation in February 2013 by the Texas Board of Educator Certification. Though 70 percent of the TAMIU education graduates passed the certification examination, state accountability standards require an 80 percent completion rate to avoid probationary status. TAMIU President Ray Keck noted that Texas Tech, Rutgers, Syracuse, and Stanford universities all fared poorly in the NCTQ study as well and asked, "Do you honestly believe those universities run slipshod programs in education?" In July 2014, the University was notified by the State Board for Educator Certification (SBEC) that its full accreditation status had been restored. In 2014, the College Affordability and Transparency Center, a project of the U.S. Department of Education, ranked the university sixth in the nation for lowest net price among public four-year universities. Research TAMIU is home to various research centers, including the Binational Center, Center for the Study of Western Hemispheric Trade, The Western Hemispheric Trade Information Center, the Texas Center for Border Economics and Enterprise Development, the Small Business Development Center and the Center for Earth and Environmental Studies. Benefactors One of the institution's largest private benefactors was Radcliffe Killam (1910-2007), a Laredo oilman who donated $2 million to establish The Center for Western Hemispheric Trade, in addition to the University's campus land.
