In many states, graduating from an accredited program is a requirement for licensure as a landscape architect and/or reduces the professional practice requirement for licensure.
According to the Landscape Architects Technical Committee (LATC):
"The traditional method to become a licensed landscape architect in California is to, 1) obtain an accredited degree in landscape architecture, 2) work directly for a licensed landscape architect for at least 2 years (with 1 year after graduation), 3) complete the LARE, and 4) complete the California Supplemental Examination.
In California a candidate must have a minimum of six years combined qualifying education and training/experience to be eligible to take the LARE. Credit for education and training/experience can be accrued as outlined in the laws governing landscape architecture, specifically CCR 2620 - Education and Training credits. There are many ways a candidate may obtain a landscape architecture license; it is always advisable for candidates to review the laws carefully, then contact the LATC for specific questions or information.Candidates should be aware that, although California accepts the education and training/experience as outlined in law, CLARB and other state licensing boards may not recognize the same education and training/experience. This can make obtaining CLARB Certification and reciprocal licensure difficult for those who deviate from the traditional method of acquiring education and training/experience for licensure."
