High School Diploma/Equivalency

Without a high school diploma, adults can’t easily find a job that will support a family. Adults can work on basic skills and earn a diploma or equivalent certificate and begin building a bridge to their future. A high school diploma is required to qualify for funding for some programs.

Finding Her Place
Hamida Hakimi Roshangar

Hamida Hakimi Roshangar left Afghanistan in 2016 to reunite with her husband who had been in the U.S. for two years already.

She brought with her a bachelor’s degree and 10 years of experience working within the Afghan Parliament. Eager to begin working in the United States, Hamida promptly submitted her résumé to many employers. Given her experience, she expected to find a job quickly. But she didn’t. This left Hakimi struggling with an overwhelming feeling of uselessness.

“I was totally lost. I lost my identity I was really helpless, really scared,” Hamida says. “There was nobody to help me. There was nobody to guide me. Where do I start from? I had no idea.”

At that point, she realized she needed to become educated in the United States to work here. Her husband had taken ESL classes through Mt. Diablo Adult Education and recommended Project ACCESS to Hamida.
