Piniella Irakoze is cold calling a list of 1,001 fellow students who didn’t return to Phoenix College this semester, checking on how they’re managing during the coronavirus pandemic.

The calls have become a regular part of her job at a community college like others across the U.S. that have experienced significant enrollment declines as students face challenges with finances, family life, and virtual learning.

“I didn’t know that so many people were struggling,” said Irakoze, 20, who studies medical laboratory science and works part-time for the college. “So many students aren’t coming back.”

Nationwide, enrollment at community colleges — which offer two-year degrees and vocational training and often attract older students looking to learn new skills — dropped 10% from fall 2019 to fall 2020, according to the National Student Clearinghouse.

They were hit the hardest amid all colleges and four-year universities experienced only slight declines, beating many predictions that the outcome would be worse.

While it was no surprise that fewer freshmen enrolled at four-year and community colleges, delaying studies until campuses fully reopen, the pandemic took a much heavier toll on older adult students who frequently choose the community college route. Many lost jobs or have no time for their own schooling as they supervise their children’s online classes.

“The majority of them are working, many of them in industries that have been decimated by the pandemic,” said Martha Parham, a senior vice president for the American Association of Community Colleges. “Trying to navigate that and take classes is a very daunting challenge at this time.”

Depression and anxiety also disrupted the academic careers of community college students, including Stephanie Cruz Vazquez.

She said her severe anxiety was amplified so much by her virus concerns that she decided last year to take a year off from fashion design classes at Mesa Community College near Phoenix.

“The pandemic really pushed me over the edge,” said Cruz Vazquez, 20.

She ended up infected with COVID-19 along with her parents. They all recovered and Cruz Vazquez now works for a local city council race campaign with plans to return to college this year.

More Americans typically turn to community college education amid economic downturns, seeking to learn new job skills or change careers. But the depth of the pandemic’s downturn, which kept many people homebound, seems to have upended usual trends, education experts said.

That troubles advocates and policymakers who cite community colleges as important options for low-income Americans. At a Senate hearing this month, Miguel Cardona, President Joe Biden’s pick for education secretary, called for federal financial support to help to hurt community colleges, calling them “this nation’s best-kept secret.”

Even in good economic times, many community college students struggle to stay in school while juggling the demands of supporting families, paying rent, and covering tuition.

The added challenge of the pandemic was too much for many students, said Ralph Thompson, interim dean of students at Phoenix College.

Its enrollment was at 10,978 in the fall of 2019 but dropped to 9,446 a year later, a decline of 14%, according to the Maricopa County Community College District, which counts Phoenix College among its 10 community colleges.

Thompson assigned Irakoze to call fellow students to see how they are coping, saying they “need to feel engaged” during their isolation.

“The students need to hear that someone understands what they are going through,” Thompson said.

Across the U.S., community colleges have reported surging demand from students who need help getting food, prompting them to expand food pantries and grocery programs — in some cases tripling the amount of food distributed in past years.
