Certified Landscape Technician Program

The CLT testing has an interesting history.  Established in 1983 by the Associated Landscape Contractors of America (ALCA), now known as PLANET (Professional Landcare Network), the CLT program was set out to recognize the proficiency in the landscape workforce, upgrade the status of the landscape professionals and provide the public with a means of identifying qualified landscape professionals.

PLANET created the test with the intent of offering a uniform test in every state in the union.  The testing began in California and is now being offered in 19 states.  PLANET contracts the rights to use the CLT test with one administrator in each state.  The New York State Turf and Landscape Association (NYSTLA) is the sole administrator of the CLT test for the state of New York and offers the test several times a year at different regional testing facilities.

The CLT test consists of two parts.  The first part involves a written exam, which tests the applicant's knowledge in all facets of the landscape industry.  The second part to the certification process is a practical examination, which is held at one of the regional test sites.  During this second testing phase, an applicant must pass the core test and one of the following three landscape specialty tests: 1) Maintenance, 2) Irrigation, and 3) Construction.  Once both phases of testing have been successfully completed, the applicant is awarded the Certified Landscape Technician designation.
