Furthermore, ATS commenced, with the aim of gathering information related to performed assessments, with the activities aiming at the upgrade of the work of the ATS assessment teams and enhancement of their efficiency, and harmonisation of assessors’ stands when performing assessments. With that end in view ATS will use a special form (Evaluation of the Performed Assessment, ATS-PR09-O02).

If you wish to express your satisfaction or even dissatisfaction, and propose improvement measures, you will need to complete the form immediately after the assessment or after the accreditation procedure has been finalised and send it to ATS to the address listed in the form. Completion of the form is voluntary.

ATS would like to take this opportunity to thank you in advance for any information, suggestion, proposal or opinion you decide to send us.
