Certified Arborists
To qualify as a certified arborist, an experienced plant care
professional must pass an extensive examination developed by
an international panel of academic and industry experts. The
International Society of Arboriculture maintains this voluntary
certification program. The educational program does not stop
with testing. A certified Arborist must keep abreast of new
technology and obtain necessary "Continuing Education credits"
by attending seminars and reviewing the latest publications.
