In the United States, approximately one-third of new teachers come through alternative routes to teacher certification, according to testimony given by Emily Feistritzer, the President of National Center for Alternative Certification and the National Center for Education Information, to a congressional subcommittee on May 17, 2007. However, many alternative pathways are affiliated with schools of education, where candidates still enroll in university-based coursework. A supplemental component of university-based coursework is community-based teacher education, where teacher candidates immerse themselves in communities that will allow them to apply teaching theory to practice. Community-based teacher education also challenges teacher candidates' assumptions about the issues of gender, race, and multicultural diversity.This assists to make an attitudinal change in the teacher trainees in order to eliminate segregation within the school community.
