SIZA strives to ensure continuous improvement among agri-businesses, allowing for economic growth, social responsibility, and environmental stewardship throughout the supply chain. This goal is achieved by ensuring reliability, ethicality, and consistency among the SIZA approved third-party audit entities. The aim of the SIZA Audit Oversight Monitoring & Evaluation Policy is to describe the rationale and process for the recognition and calibration of audit entities and auditors to ensure quality, competency, and compliance are maintained throughout the process.

SIZA has embraced a third-party audit approach, aiming for a credible and objective evaluation that accurately reflects both the audit outcome and the relevant social and/or environmental requirements within a business. Consequently, aspiring auditors seeking to audit according to the SIZA standard must apply to one of the recognised audit firms. Upon appointment by a specific firm, adherence to certain stringent criteria becomes essential and a prerequisite for recognition. SIZA remains dedicated to establishing robust processes, ensuring that monitoring and measurement of the SIZA Standards align with the programme's methodology and adhere to the SIZA Social and/or Environmental Standard. Given the challenges inherent in auditing, it is imperative to select individuals who are not only well-suited for the position but also willing to embark on the demanding and costly journey to become a Lead Auditor. Thus, careful consideration of traits and commitment is vital for success in this chosen career path.


SIZA endorses the auditor’s recognition programme as designed by The Association of Professional Social Compliance Auditors (APSCA) as a requirement to audit companies to apply for acceptance to be recognized by SIZA. On top of this requirement, SIZA’s Auditor Competency reference tools describe who can perform audits, and will be used as the basis for the recognition of not only audit companies, but also auditors for the SIZA programme. Audit companies must independently submit their registration to APSCA for the equivalence process, and only those who complete the programme successfully can apply to be recognized by SIZA.

The competency and accreditation of the audit company is crucial to the integrity of the SIZA audit programme. Part of this process ensures the objectivity and reliability of the audit company. By adopting this approach, SIZA ensures its independence from the audit companies and drives a robust and reliable process. A Service Level Agreement is in place between SIZA and each audit firm to ensure adherence to the APSCA and the SIZA audit oversight principles.

SIZA is committed to establishing suitable processes to ensure that the SIZA Code monitoring and measurement can be carried out in a manner that is consistent with the SIZA Social Standard and the SIZA Audit Process & Methodology
