Contact the American Society of Landscape Architects, or ASLA. They can give you a list of schools that are accredited, as well as inform you of class and degree requirements. The ASLA is a good resource for anyone looking to begin a landscape architecture degree program or change architectural specializations.
Choose a school that offers landscape architecture as a degree option and that is accredited by the ASLA. Landscape architecture is usually listed with architectural, engineering or ecological degrees. Look for the landscape architecture specialization in which you are interested. Some specializations include urban design, parks and recreation planning, regional planning, ecological planning, heritage conservation and landscape restoration. There are many other specializations as well.
Choose a degree that best fits your goals. The Bachelor of Landscape Architecture, or BLA, and the Bachelor of Science in Landscape Architecture, or BSLA, can take up to five years of study to complete. The Master of Landscape Architecture, or MLA, can take an additional three years to complete. Know what the requirements are for the career you wish to pursue. If you already have a bachelor's degree in architecture, a MLA could take as little as two years to complete.
Research the required classes for the landscape architecture degree you wish to obtain. This is especially important if you are a student transferring schools, changing academic majors or shifting the focus of an academic major from one specialization to another. You may be able to transfer previous credits, depending on the degree requirements. Landscape architecture required classes often include landscape design and construction, surveying, ecology, site design and planning, urban and rural planning, geology, horticulture, and general earth or environmental sciences.
Talk to a college adviser about your intent to begin a degree in landscape architecture, transfer schools or change majors. An adviser can provide answers about school transfers, credit transfers and academic major changes.
