Certified Kitchen Designers (CKDs) specialize in the design, planning and execution of kitchens, bathroom vanities and other built-in units throughout the home. Only a select group of expert designers attain the CKD designation(s). CKDs must meet common core educational requirements, adhere to various legal restrictions and regulations in practice, and follow a professional code of ethics. The CKD is competent beyond the minimum interior design qualifications of federal and state (provincial) legal codes and requirements. CKDs prove advanced knowledge of technical and personal communication skills required to succeed as a design specialist in residential kitchen, bathroom and other built-in environments.
