About Us

From 2006 to Present

In 2006, QSI was established in Istanbul by UK-based GLOBAL CERTIFICATION, which provides UKAS Accredited Certification Service.

Between 2006-2010, QSI provided services on UKAS Accredited Certification Service, SAAS Accredited SA 8000 Certification and IRCA Approved Lead Auditor Training under GLOBAL CERTIFICATION.

QSI Certification, authorized by the Turkish Accreditation Organization -TÜRKAK in 2010 for ISO 9001 and ISO 14001 Certification, successfully carries out certification activities in several small, medium and large-sized organizations.

In 2016, QSI has become the First Verifier Body in our country within the scope of the Greenhouse Gas Verification Regulation published by the Ministry of Environment and Urbanization.

In 2020, QSI Certification, which started to provide Management Systems Lead Auditor trainings as the Authorized Educational Institution of the International Training Organization Exemplar Global, carries out many successful training organizations with the slogan We do not teach, we educate.

The main purpose of QSI Certification, which has been providing service with the motto "Objective Perspective" since its establishment, is to contribute to the improvement of the processes of its customers with its expert team.
