The objective of this study was to investigate Black teachers' perceptions of their impact on Black student achievement. Study participants included teachers with 2-15 years of experience from neighboring school districts in the mid-Atlantic region of the United States. Data were collected during school-year 2011-2012. Methods included journal writing, focus groups, interviews, and a questionnaire. Findings reveal that teachers found it difficult to positively impact Black student achievement because of frustrating situations they faced, including institutional, pedagogical, relational, positional, and cultural frustrations. The findings complicate the portrayal of Black teachers as culturally synchronized othermothers, mentors, and role models for Black students and highlight the negative, unintended consequences of the Brown v. Board of Education ruling. [ABSTRACT FROM AUTHOR]
