What is a requirement for professional competence according to the AICPA code of professional conduct?

The requirement for professional competence, as outlined in the AICPA Code of Professional Conduct, highlights the importance of possessing knowledge of relevant technical subject matter or having the capacity to acquire such knowledge as necessary. This principle emphasizes that CPAs must ensure they have the necessary skills and understanding to perform their professional duties effectively and with due care.

Having the ability to acquire knowledge implies a commitment to continuous learning and professional development, which is essential in a field that evolves with changing regulations and standards. This ensures that CPAs can provide competent and high-quality services to their clients, thereby upholding the integrity of the profession.

The other options do not align with the requirement for professional competence as stated by the AICPA. Engaging only in work familiar to you, being restricted to sole practitioners, or only working under supervision may limit the ability to develop a broad and comprehensive understanding of the standards and practices necessary for the diverse challenges within the profession.
