CLARB is a non-profit association of the state and provincial registration boards that regulate the profession of landscape architecture in North America. It is the governing body that administers the L.A.R.E., Landscape Architect Registration Examination. This exam is designed to determine whether applicants for landscape architectural licensure possess sufficient knowledge, skills and abilities to provide landscape architectural services without endangering the health, safety and welfare of the public. It is given to graduates of universities that have accredited programs in the field of landscape architecture and who have completed the required post graduate internship (under the direct supervision of a registered landscape architect). Currently 46 states require by law that you must meet all criteria established by CLARB before you can practice and/or be called a "landscape architect". Conversely, by law, anyone can be called a landscape designer, master gardener, or any other such term as no such nationally recognized governing agency exists to ensure that the person has been held to this strict standard of education and training.
