Teachers can have bachelor's degrees, master's degrees or doctoral degrees (E.D. or PhD.) but by themselves, the qualifications of teachers won't make up for the fact that 20% of our children live in poverty.

"The relationship between SES [socioeconomic status] and achievement was consistent across all 20 countries. Students with highest levels of SES, as measured in this study, had an educational advantage over their lowest SES counterparts. This reinforces the associations previously documented in the literature both in the United States and abroad between SES and student educational achievement."— U.S. Department of Education, National Center for Education Statistics (NCES, April 2006)
