An accountant is a practitioner of accounting or accountancy. Accountants who have demonstrated competency through their professional associations' certification exams are certified to use titles such as Chartered Accountant, Chartered Certified Accountant or Certified Public Accountant, or Registered Public Accountant. Such professionals are granted certain responsibilities by statute, such as the ability to certify an organization's financial statements, and may be held liable for professional misconduct. Non-qualified accountants may be employed by a qualified accountant, or may work independently without statutory privileges and obligations.
