CLEVELAND — JobsOhio is investing $300 million to help train Ohioans for future employment opportunities across the state.

The commitment was announced at the Rockefeller Foundation’s Big Bets for America conference in Cleveland on Tuesday.

“This $300 million is going to work with employers and create a classroom-to-career scenario for Ohio’s workers,” JobsOhio President and CEO JP Nauseef said.

The program will start rolling out in July and continue for the next decade. Nauseef estimates it will impact at least 50,000 new workers.

“This is aimed at getting people prepared for real jobs in the real world,” Gov. Mike DeWine said at the event Tuesday.

The Big Bets for America conference is a traveling conference that highlights local approaches to issues affecting communities across the country. DeWine hopes the stop in Ohio will attract more businesses and investment to the state.

“We got to make sure we have the people,” he said. “Got to make sure the people that we have get the training that they need, so they can have a good job, and so they can help us attract more companies here.”

Nauseef said JobsOhio has spent years working to attract businesses that provide high-quality jobs to the state. Recent projections indicate Ohio will need half a million STEM-related employees over the next decade.

“If you look in the middle of that bell curve, it’s mostly technicians, manufacturing technicians,” he said. “Because again, we’re a place you can actually build it.”

The job readiness fund wasn’t the only investment announced Tuesday.

The Wellman Family, Key Bank and the Rockefeller Foundation also committed to supporting Cleveland’s Site Readiness for Good Jobs Fund. Their combined investments will add $13 million to the fund, bringing its total to $80 million.

It will turn vacant land into shovel-ready sites for development, hoping to attract more investment and jobs to the region.
