Your education and experience will determine the steps you'll take to get your license.
If your degree is in field other than landscape architecture, you'll be required to have additional qualifying experience in landscape architecture under the direct supervision of a licensed landscape architect. To find out more about eligibility requirements go to http://www.clarb.org.
You'll need to document 8 years of diversified experience working in landscape architecture, and 6 years of that experience must be under the direct supervision of a licensed landscape architect. Post-secondary education in landscape architecture may count as part of your experience.
If you're registered or licensed as a landscape architect in another state or territory of the United States, the District of Columbia, or another country you may apply for a license in Washington. However, you must meet Washington's licensing requirements.
