CAS case studies

The Certified Advertising Specialist (CAS) is a professional credential for practitioners who plan, buy, build, and measure advertising across traditional and digital channels. It suits media planners, account and campaign managers, digital marketers, creative producers, and in-house marketing leads who want a structured way to demonstrate breadth rather than depth in a single channel. The exam is delivered in multiple-choice format and is organized around eight domains: advertising strategy and planning, campaign management, media planning and buying, creative development and production, digital advertising and analytics, measurement and attribution, budgeting and ROI, and professional ethics and compliance. Expect questions that test judgment as much as recall - choosing a media mix under a fixed budget, spotting a flawed attribution setup, or deciding whether a claim or targeting practice raises a compliance problem. The CAS case studies are 5 cases and about 3,997 words.
