A customer service certificate program is an ideal way to prepare for a career as a CSR (customer service representative). Certification programs allow students to become proficient in all areas of customer service, including customer communications, office organization and computer application usage. Customer service courses teach students to communicate more effectively, organize and maintain business records, use the latest computer software and resolve customer problems or questions. This field reaches across industries, as most companies need to maintain positive, open relationships with their customers or clients.
