An organization headed by former tennis player Andre Agassi says it will pay the entire $7 million in construction costs for a new charter school in Nashville. The Nashville Tennessean says Rocketship Nashville Elementary School has secured a site and it is eying an early January groundbreaking on a 37,000-square-foot building and gymnasium. Canyon-Agassi Charter School Facilities Fund — which delivers capital funding for new charter facilities — purchased the site for $375,000 in October and is paying for the building’s construction.
