NCEES Principles and Practice of Engineering Examination

CONTROL SYSTEMS Exam Specifications

Effective Beginning with the October 2011 Examinations

The exam is an 8-hour open-book exam.It contains 40 multiple-choice questions in the 4-hour morning session, and 40 multiple-choice questions in the 4-hour afternoon session. Examinee works all questions. The exam uses both theInternational System of units (SI) and the US Customary System (USCS). The exam is developed with questions that will require a variety of approaches and methodologies, including design, analysis, andapplication. The knowledge areas specified as examples of kinds of knowledge are not exclusive or exhaustive categories.
