What is the difference between ISA 220 and ISQM 1?

ISA 220 and ISQM 1 are International Standards on Auditing developed by the International Auditing and Assurance Standards Board (IAASB). While both standards address quality control, there are some key differences between the two.

ISA 220 focuses specifically on quality control for audits of financial statements. It outlines the requirements for establishing and maintaining an effective quality control system for an audit firm.

This standard ensures that the engagement team has the necessary competence, resources, and ethical values to conduct an audit engagement by professional standards.

On the other hand, ISQM 1 addresses the broader scope of quality control systems for firms that perform assurance engagements, including audits of financial statements, reviews, and other assurance and related services engagements.

ISQM 1 requires the firm to establish and maintain a quality control system to reasonably ensure that the firm and its personnel comply with professional standards and regulatory and legal requirements.

It also requires the firm to monitor its quality control system to remain relevant, adequate, and effective.

Another key difference between the two standards is that ISQM 1 emphasizes the role of firm leadership in establishing and maintaining the quality control system.

It requires the firm’s leaders to take responsibility for the quality control system, establish policies and procedures, monitor compliance, and take corrective action when necessary.
