MENLO PARK, Calif – Facebook is blaming its failure to diversify its predominantly white male workforce on the country’s lackluster education system, though some believe the company is simply making excuses.

The social media giant released an annual diversity report last Thursday that sows the company’s U.S. workforce remains only about 2 percent black and 4 percent Hispanic. Facebook’s technical staff is even less diverse, with only 1 percent black and 3 percent Hispanic, according to SFGate.com.

Those figures have remained pretty much unchanged since 2014, and the company’s global head of diversity, Maxine Williams, argued the U.S. public education system is the reason.

“It has become clear that at the most fundamental level, appropriate representation in technology or any other industry will depend upon more people having the opportunity to gain necessary skills through the public education system,” Williams posted to Facebook’s newsroom last week.

“Currently, only 1 in 4 US high schools teach computer science. In 2015, seven states had fewer than 10 girls take the Advanced Placement Computer Science exam and no girls took the exam in three states,” she wrote.  “No Black people took the exam in nine states including Mississippi where about 50% of high school graduates are Black, and 18 states had fewer than 10 Hispanics take the exam with another five states having no Hispanic AP Computer Science (CS) test takers.

“This has to change.”

Williams touted a $15 million donation to the nonprofit Code.org over the next five years to “drive the development of curricula, public school teacher-training and student skills-building, particularly among traditionally underrepresented populations in engineering and computer science.”

She also outlined a variety of other initiatives Facebook is engaged in to diversify the tech industry.

Williams claims that despite the problems with public schools, the company is making headway in recruiting minority talent.

“We still have a long way to go, but as we continue to strive for greater change, we are encouraged by positive hiring trends,” she wrote. “For example, while our current representation in senior leadership is 3% Black, 3% Hispanic and 27% women, of new senior leadership hires at Facebook in the US over the last 12 months, 9% are Black, 5% are Hispanic and 29% are women.”

The problem with Facebook’s assessment of the tech industry, however, is that it’s dead wrong, critics contend.

“Data contradicts Williams’ statements … There are actually more black and Hispanic students who major in computer science and engineering than work in jobs in the tech industry, according to USA Today,” Digital Trends, an industry news site, reports.

“A study by the Equal Employment Opportunity Commission showed that among top engineering programs, 9 percent of graduates are black and Hispanic. The study further shows that total black and Hispanic workforce at major technology companies sits around 5 percent.”

Facebook’s excuses for its lack of diversity also sparked the ire of Kaya Thomas, who penned a blog for NewCoShift that takes the social media site to task for “passing off the issue to the public education system.”

The black Dartmouth College computer science major wrote that “there are thousands of other Black and Latinx who graduate every year with computer science Bachelor degrees.

“Most of us don’t get hired into the tech industry. So instead of putting in the effort to look for us, Facebook is ignoring the fact that we even exist,” she wrote.

Thomas continued:

I wish that tech leaders would just be honest and admit that they’ve made tech culture so exclusive and toxic. Ignoring the fact that underrepresented talent exists shows e that they don’t care about diversity and they don’t want us working in tech.

Most of tech recruiting is currently not built to look for great talent. I’m not interested in ping-pong, beer, or whatever other gimmick used to attract new grads. The fact that I don’t like those things shouldn’t mean I’m not a ‘culture fit.’ I don’t want to work in tech to fool around, I want to create amazing things and learn from other smart people. That is the culture fit you should be looking for.

Tech entrepreneur and investor Kathryn Finney told Forbes that Facebook and other tech firms talk a good talk on diversity, but don’t walk the walk.

“They’ll give money to a coding program for kids, but just enough to show they kind of care,” she said. “The challenge for tech is this: black people are your customers. If you don’t figure this out, you’re going to have a big problem.”

Finney said the emphasis on a “culture fit” for new hires is perhaps one of the biggest barriers for minorities looking to break into the industry.

“What they’re really saying is, there aren’t enough black and Hispanic graduates who fit in,” she said.
