One usual way to be sure a specific piece of information, detail, or appointment is accurate and true is through the use of a letter of certification. Certification is a common way of verifying information publicly.

What is a Letter of Certification?

A certification letter is a written document of acknowledgment or verification that a piece of information or details is true. It is also a letter written to verify or certify information at hand in the process of applying for something or having completed a task or training. It could include details or information that includes; dates, titles, and names of individuals involved in the situation or event being certified. Certification is a formal attestation or confirmation of certain attributes of an object, person, or organization, whereby a written assurance is provided by an independent body that a product, service, or system in question meets required standards. For instance, while undergoing a program or course that enhances your personal and technical skills, upon successful completion of the said program or task a certificate is handed to the participant or individual who certifies that such individual is qualified and competent to practice in whatsoever area they specialized on during the program.
