CPLS™, Certified Parking Lot Striper™, is the credential that proves a contractor knows the standards their work has to meet. Three tiers cover foundational competence, ADA and specialty work, and master-level project management.

A CPLS-certified contractor has passed a standardized exam, met continuing education requirements for renewal, and agreed to PLSIC™'s professional standards. The credential is verifiable in the PLSIC directory and belongs to the individual, not the company. It moves with them across employers.

Each tier builds on the previous, advancing from PLSIC-2027 master specification literacy and surface preparation through ADA layout and specialty markings to multi-site program management. Founding members lock the early-access window through September 14, 2026.
