And to make sure everyone feels welcome, the group provides students with access to mentors from similar backgrounds. “Having representation from people who resemble them as much as possible is really important,” she says. Some codersof.colour participants have already gone on to study computer science in college or score jobs in the tech industry. And there’s another big payoff: Greater inclusion means better products. “Diversity is an easy business case to make,” she says. “Technology is something we all have to interact with, so it should be accessible to all o...
