Most PE exams consist of two four-hour sessions separated by a lunch break. The morning section is a breadth exam and the afternoon section is a depth exam, focusing on a specific area of the discipline. Each section consists of 40 multiple-choice questions. The exception is the Civil Structural exam, which takes place over two days, with multiple-choice breadth exams in the morning and essay depth exams in the afternoons. There is no set number of questions that you must get right in order to pass. It varies from one testing administration to another. In order to account for differences in difficulty between the different versions of the exam, NCEES uses a process called equating. This assigns a weight to each question based on its difficulty so that the passing score for each exam demonstrates the same level of knowledge. There is no penalty for incorrect answers, so it’s always best to guess if you’re not sure of an answer. Results for computer-based tests are available through your online account within seven to 10 days of the exam. Paper test takers will have to wait eight to 10 weeks for their scores to be released. Most exams are graded by a machine, though a handful are graded by humans to ensure accuracy. You can request that your exam be graded manually, but this costs extra.
