Question 1

What is the difference between the PE and the SE?

Accepted Answer

A PE (Civil with a Structural depth) is the baseline engineering license. The SE (Structural Engineering) is an advanced 16-hour exam for designing significant or high-risk structures; some states require it specifically to practice structural engineering or use the "Structural Engineer" title.

Question 2

How long is the SE exam?

Accepted Answer

The SE is a 16-hour exam split into two 8-hour components — Vertical Forces (gravity/incidental lateral) and Lateral Forces (wind and seismic). Many candidates take the two components separately.

Question 3

Is the structural PE exam open book?

Accepted Answer

The PE Civil: Structural is open-book using an NCEES-supplied reference. The SE exam is open-book with your own bound design standards (AISC, ACI, ASCE 7, NDS, TMS). Both are time-pressured, so fast reference navigation is essential.

Question 4

Do I need the SE or is the PE enough?

Accepted Answer

For much structural work a PE is sufficient, but designing significant structures — and practicing in certain states/jurisdictions — requires the SE. Check your state board and the projects you intend to stamp.
