Ferrari will evaluate Sergio Perez during a test with the Italian team's 2009 car later this year.
Mexican rookie Perez, backed strongly by Mexican billionaire Carlos Slim, is making his Formula One debut in 2011 for the Ferrari powered Swiss team Sauber.
The pair are tipped as possible long-term replacements for Felipe Massa.
Driver academy director Luca Baldisserri announced this week that Perez and Bianchi will be testing at Mugello or Fiorano in September.
"I think they will both be very motivated and for us it will be the perfect opportunity to assess both drivers," he said.
