The Outstanding Contribution Certificate is the third highest level service certificate. Unlike the Distinguished Service and Meritorious Service Certificates, this certificate is given for a specific achievement of major value and significance to the IEEE Computer Society. The achievement should be a specific, concisely characterized accomplishment, as opposed to a collection of different efforts. Examples are: the successful launching of a major conference series, a specific publication, standards and model curricula. A group OC award may be given for a major contribution in which a number of volunteers each made significant contributions. Certificates bearing all names would be awarded.
