The operator obtains and reads the National Organic Standards, and conducts a self-assessment to see if the operation meets these requirements in terms of land history, production practices, materials used and recordkeeping procedures. In many cases, some practices and systems need to be modified to comply. Once an operation complies, the operator then selects an accredited certifier, submits an application, gets inspected, meets any conditions identified by the certifier, and obtains a certificate.
