Accy 1.201(1)(1) A person licensed to practice as a certified public accountant shall comply with all of the following general standards as interpreted by bodies designated by the American Institute of Certified Public Accountants Council, and must justify any departures therefrom:

Accy 1.201(1)(a)(a) Professional competence. A certified public accountant shall undertake only those engagements which the certified public accountant or the firm can reasonably expect to complete with professional competence.

Accy 1.201(1)(b)(b) Due professional care. A certified public accountant shall exercise due professional care in the performance of an engagement.

Accy 1.201(1)(c)(c) Planning and supervision. A certified public accountant shall adequately plan and supervise an engagement.

Accy 1.201(1)(d)(d) Sufficient relevant data. A certified public accountant shall obtain sufficient relative data to afford a reasonable basis for conclusions or recommendations in relation to an engagement.

Accy 1.201(1)(e)(e) Forecasts. A certified public accountant shall not permit the certified public accountant’s name to be used in conjunction with any forecast of future transactions in a manner which may lead to the belief that the certified public accountant vouches for the achievability of the forecast. This paragraph does not prohibit a certified public accountant from preparing, or assisting a client in the preparation of, forecasts of the results of future transactions. When a certified public accountant’s name is associated with such forecasts, there shall be the presumption that such data may be used by parties other than the client. Therefore, full disclosure must be made of the sources of the information used and the major assumptions made in the preparation of the statements and analyses, and character of the work performed by the member, and the degree of the responsibility he or she is taking.

Accy 1.201(2)(a)(a) A certified public accountant who accepts a professional engagement implies that he or she has the necessary competence to complete the engagement according to professional standards, applying the certified public accountant’s knowledge and skill with reasonable care and diligence, but the certified public accountant does not assume a responsibility for infallibility of knowledge or judgment.

Accy 1.201(2)(b)(b) Competence in the practice of public accounting involves both the technical qualifications of the certified public accountant and his or her staff and the ability to supervise and evaluate the quality of the work performed. Competence relates both to knowledge of the profession’s standards, techniques and the technical subject matter involved, and to the capability to exercise sound judgment in applying such knowledge to each engagement.

Accy 1.201(2)(c)(c) The certified public accountant may have the knowledge required to complete an engagement professionally before undertaking it. In many cases, however, additional research or consultation with others may be necessary during the course of the engagement. This does not ordinarily represent a lack of competence, but rather is a normal part of the professional conduct of an engagement.

Accy 1.201(2)(d)(d) However, if a certified public accountant is unable to gain sufficient competence through these means, he or she should suggest, in fairness to the client and the public, the engagement of someone competent to perform the needed service, either independently or as an associate.
