Mentors, Surratt says, can give black boys the kind of positive role models they may be lacking in home or at school, and from experience can provide lessons on how to cope with challenges. “It’s not a cultural deficiency model,” says Surratt, referring to a model that says young black men are broken and need to be fixed. “It’s an asset richness model”—one that takes the assets that already exist in the African-American community and puts them to work guiding young men who may be struggling into responsible adulthood.

Our Best also includes a new mayor’s council on black male achievement, with the goal of increasing the number of black boys who graduate high school; providing young black men between the ages of 14 and 24 more pathways to “meaningful,” well-paid employment; and reducing the percentage of young black men entering the criminal justice system.

While the city’s renewed focus on young black male achievement is both admirable and necessary, some worry that male-focused programs like Our Best leave black girls behind.

Black girls are six times as likely as white girls to get kicked out of school—a racial gap in suspension rates that dwarfs the gap between black and white boys.

Like those of their male counterparts, black girls’ reading and math scores are at or near the bottom level, and four in 10 black girls who drop out of school cite pregnancy or parenthood as the reason. Black girls who drop out may suffer greater economic consequences than black boys, largely because the jobs that are available for female high school dropouts pay significantly less than those available to male dropouts. Black girls are also far more likely to be single parents without other sources of support, which compounds the impact of lower wages. Little wonder, then, that the median net worth of single black women is $100, compared with almost $7,900 for black men and $41,500 for single white women.

Moreover, black girls experience harm at school that the standard “achievement gap” yardstick simply fails to measure, such as sexual violence, suicide, harassment and the consequences of single parenting, says Kimberlé Williams Crenshaw, the founder and director of the African American Policy Forum and a law professor at UCLA and Columbia University.

“There is a whole range of ways that girls are impacted by these environments that people aren’t even talking about because the point of departure is always the boy,” says Crenshaw. Much like health research that for many years only used male subjects, the data available on African-American student achievement is largely centered on outcomes that primarily impact boys, such as the school-to-prison pipeline, creating a feedback loop that leaves girls out. “It’s not just one gender that’s struggling, [but] the conversation up ’til now has assumed that the only students in crisis were boys,” says Crenshaw.

Proponents of Our Best say they’re aware that girls face specific challenges that boys don’t. “We all know that our young ladies need support as well,” Chappelle says. But, he says, “We have to get that infrastructure in place first, and then we will be able to provide the young ladies with support, too.” Supporters of Our Best also insist that by helping young men, the program will benefit young black women as well, by fixing systems that hurt everybody when they’re broken.

“The intent is that if you fix a demographic that is clearly doing statistically the poorest, you are in fact fixing the institutional problems for the other demographics as well,” says City Council member Bruce Harrell, an Our Best proponent. “In fixing a lot of the institutional practices that work to the detriment of young black males, I think young black females and even others will reap the benefits.”

Surratt adds, “Unfortunately, across almost every metric that you can imagine, every social, economic and health indicator, young black men are suffering the most, and so we wanted to tackle this part of the community first.”

Crenshaw, who criticized Obama’s My Brother’s Keeper program for excluding girls in a New York Times op-ed piece, is less convinced, calling that theory “trickle-down social justice” that “doesn’t work any better than Reaganomics did.”

Chappelle points to the fact that at least one school in Seattle that implemented the My Brother’s Keeper program, Aki Kurose Middle School, has since added an analogous Our Sister’s Keeper program for girls as evidence that the program will probably expand—eventually.

“Once we get Our Best down as far as young black men are concerned, then I would anticipate we would figure out a way to make sure that we are weaving in the support we need for our young black women, and also other young women of color who have historically been marginalized,” Chappelle says. The question is, how long will it take? And will it be soon enough to help the latest generation of young black girls who are at risk of falling through the cracks?
