You must first be awarded Member (MCIM) or Fellow (FCIM) graded membership and then complete two consecutive years of CPD, followed by an online assessment.
Under the current CPD programme, you will need to complete four reflective statements during each CPD year for a minimum of two consecutive years. On completion of your second consecutive year, you will need to complete the Chartered Marketer assessment. This is based on the Professional Marketing Competencies and you will need to answer a series of multiple choice questions to complete the assessment. Once you have met this criteria, you will be awarded Chartered Marketer status.
