Candidates are judged on work methods, adherence to best practices, and safety ideals. Each problem had a time limit set for its completion. Candidates may test at any state's test site. Applicants are given written tests indoors; followed by a series of hands-on, timed problems outdoors, supervised by one or more judges. Most problems require applicants to install or maintain sample landscape projects.
