To ensure the highest standards of organizational integrity, the Philippine Tax Academy (PTA) conducted a three-day Intensive Auditor Training on ISO 19011:2018 from April 28 to 30, 2026.

With management consultant Mr. Rosandro G. Bertis as the resource speaker, the program equipped our Auditors and Audit Team Leaders with the essential principles, techniques, and methodologies needed to perform structured and value-adding internal audits. By aligning with ISO 9001:2015 requirements and industry best practices, PTA continues to strengthen its internal oversight to guarantee efficient, transparent, and high-quality services.
