The purpose of this guide is to support organizations as they answer questions during the self-assessment application. Please note that the explanations highlighted in blue may not apply to every type of organization. Many of the items listed in the self-assessment should be included in the organization’s internal policy. The guide is organized by the title of tabs in the self-assessment. The organization must review the NCCER Accreditation Guidelines before completing the self-assessment. Please be aware that the organization’s internal policy will be reviewed during NCCER’s initial on-site audit of the ATS. Items missing from the ATS’s internal policy will result in cited non-conformance.
