Your CCSL™ certification is valid exactly for three years from the date of award. The reason is that because of continuously changing and evolving Customer Service industry, the knowledge and skill requirements for the Customer Service manager function also change and since the GSQI standards evolve in tandem, all CCSL™ certified individuals are required to either recertify or upgrade to the new level.
