The OPC Training Institute (OPCTI) is the largest OPC training company in the world. OPCTI offers hands-on classes both in-person and online. Unlike other companies that offer vendor-biased information, OPCTI focuses strictly on training and does not sell its own products. Currently, the OPC Training Institute is the only organization permitted to award the Certified OPC Professional (COP) designation to professionals.
