Study: Black Students More Likely to Graduate if They Have One Black Teacher

If a low-income black student has just one black teacher in elementary school, that student is significantly more likely to graduate high school and consider attending college, a new John Hopkins University study has found. 

Teacher 2 800px[1].jpgA low-income black student's probability of dropping out of school is reduced by 29 percent if he or she has one black teacher in 3rd, 4th, or 5th grades. That student is also 18 percent more likely to express interest in college after graduating. There was an even stronger effect for black boys from persistently low-income homes: Their probability of dropping out of school is reduced by 39 percent if they have one black teacher, and they are 29 percent more likely to consider college. 

These results come from a longitudinal study that tracked 100,000 black students who entered 3rd grade in North Carolina public schools between 2001 and 2005 all the way up through 12th grade. 

Researchers later replicated their findings in Tennessee, by looking at black students who entered kindergarten in the late 1980s through a class-size-reduction program. Those students who had at least one black teacher in kindergarten through 3rd grades were 15 percent less likely to drop out, and 10 percent more likely to take a college entrance exam.

The paper was published by the Institute of Labor Economics in March. Co-author Nicholas Papageorge, an assistant economics professor at JHU's Krieger School of Arts and Sciences, told Education Week Teacher that while he wasn't sure why there was a link between teachers' race and positive outcomes for black students, he had some ideas.

First, it could be that some of the black teachers in the study were just better teachers. Another option is that this is an example of the role-model effect.

"We think that students, especially poor black boys, might not identify with higher levels of education; they might not see people with high levels of education that look like them," he said. "If that's the case, they might not be making investments in their own education ... because they just [don't] identify with being an educated professional." 

Another possibility is that black teachers, Papageorge said, tend to have higher expectations of future educational attainment for black students than white teachers do. Those high expectations matter, he said, pointing to a study he published last year, which found that compared to black teachers, white teachers are 40 percent less likely to expect that their black students will graduate high school.

Only 7 percent of public school teachers are black. Research has found that black teachers are less likely to suspend, expel, or give detention to black students, who are disproportionately given exclusionary discipline. 

Other notes from the study: Papageorge said the researchers couldn't detect if the gender of the black teacher had an impact. Only 2 percent of teachers are black men, so the sample size simply wasn't large enough. Also, when the reseachers looked at the full sample of black students, of all income levels, they didn't see the same effect. That's partly because in general, black girls drop out of high school much less frequently than their male counterparts, Papageorge said, although having a black teacher did make black girls more likely to be interested in college.

Also, importantly, there wasn't a significantly higher effect when a black student had more than one black teacher during elementary school. 

"I found that to be encouraging, because suppose we found that you really need three black teachers over the years to make any difference at all," Papageorge said. "It would just make the policy more difficult to implement [through increased recruitment of black teachers]. That will take some time." 

Now, "we can start implementing policies tomorrow," he said, adding that school administrators can be more thoughtful when assigning students to teachers.

"We want to make sure that every black student has classroom time with a black teacher because of this effect," he said.
