How good does a translator / a company have to be to be admitted into the Certified PRO Network? Are only elite translators / companies admitted?

The level screened for inclusion into the network is not "good" or "elite" but "adequate". In the case of translators, the screening process seeks to establish only that the applicant meets or exceeds certain minimum professional standards in three screening areas: translation ability, business reliability and "citizenship". In the case of companies, two main areas are screened for adequacy: business reliability and "citizenship".
