(NRPA) Certified Sustainable Landscape Professional (CSLP) Certification Exam

(NRPA) Certified Sustainable Landscape Professional (CSLP) To sit for CSLP, you’ll typically need at least two years of professional landscape experience plus a high school diploma or equivalent—though some candidates combine formal horticulture education with fewer years in the field. The exam itself assumes a decent handle on soil science, irrigation design, and native plant selection. Without hands-on familiarity with landscape construction details and environmental site assessment methods, you’ll struggle through scenario-heavy questions that demand practical judgment, not just textbook knowledge.
