AC Diagnostics accreditation is a four year cycle with an assessment every two years and a certificate that is valid for four years.
New AC Diagnostics applicants must submit a self-assessment within a year of application. An initial assessment visit can occur in as little as four months after completion of the self-assessment. It will take about five months after the initial assessment to correct any non-conformances identified and for AC Diagnostics to issue an accreditation certificate. New applicants may receive a surveillance visit about one year after the issuance of their certificate. A surveillance visit will occur two years after the initial visit. Full reassessment will occur in another two years. Thereafter, assessment visits and surveillance visits will alternate every two years. Additional focused surveillance visits for cause may be required during the four-year accreditation cycle.
