Certification or Licensing
Though there are no national certification standards, many states require certification for workers who apply pesticides. Other states require landscape contractors to obtain a license.
Voluntary certification is available to those who want increased opportunities or to advance their career. The National Association of Landscape Professionals offers the landscape industry certified technician credential, as well as specialty credentials in softscape installation, hardscape installation, irrigation, ornamental maintenance, and turf maintenance.
Other organizations, such as the Professional Grounds Management Society and the International Society of Arboriculture, offer additional levels of certification based on education and experience levels.
