The Certified Purchasing Manager (C.P.M.) title and C.P.M. service marked initials are the exclusive and sole property of the Institute for Supply Management™ (ISM). Those who have obtained the C.P.M. can be proud of their commitment to professional and ethical standards as evidenced by their hard work to meet the program criteria established for the C.P.M.
Once qualified, ISM grants each C.P.M. the right to use the designation after his or her name on correspondence, business cards, and so forth, for as long as the applicant's certificate remains in force and effect. Use of the C.P.M. is an excellent way to announce the individual has joined a select professional group widely acknowledged by peers and management alike to be among the best prepared in today's competitive world of purchasing and supply management.
Periods must be used after each C, P, and M letter. Without the periods, another certification type is being indicated which is not related to the purchasing and supply management profession. If the individual has multiple designations from ISM, the designations must appear in the following order: CPSM, C.P.M., A.P.P.
Once a current certificate has lapsed the individual may no longer use the initials.
