PE exam pass rates

NCEES has successfully converted, or is in the process of converting, all exams to a computer-based format. To learn more about how a particular exam is administered, select a discipline from the table below.

Pencil-and-paper (P&P) exam format

Most PE exams are currently offered in pencil-and-paper format and available once or twice per year depending on the examinee population. Pass rates are updated after results are released—typically in May for the April exams and in December for the October exams. See the current pencil-and-paper exam schedule.

Computer-based testing (CBT) exam format

Some PE exams are administered year-round via computer-based testing. For these exams, pass rates are shown for the January–June or July–December population (updated in July and January, respectively).

Other CBT exams that have a smaller examinee population are administered on a single day in October each year. For these exams, the pass rates are updated in November. Learn more about the conversion to computer-based testing.
