ASLA Online Learning presentations provide information on new and evolving practices and products. These distance learning opportunities are also a convenient and affordable way to earn Professional Development Hours (PDH) needed to meet state licensure requirements. PDH are approved by the Landscape Architecture Continuing Education System (LA CES) and can be earned after viewing a presentation by completing and passing a self-study exam. Be sure to check state mandatory continuing education requirements to ensure that LA CES courses are compatible with your state requirements.
