FE retake waiting period: your earliest retake date
Short answer
There is no fixed number of days. NCEES allows one FE attempt per testing window — the calendar quarters — and no more than three in any 12 months, so your earliest retake is the first day of the next quarter. Sit in May and you can sit again from 1 July. Your board may be stricter.

Find your earliest retake date
Example: sat on 30 March, next window opens 1 April. Sat on 1 April, wait until 1 July.
The date is when NCEES lets you sit, not when you are ready. Build a free retake plan from your diagnostic report.
Earliest retake date by the month you sat
| If you sat in | Testing window | Earliest next attempt |
|---|---|---|
| January | January–March | 1 April |
| February | January–March | 1 April |
| March | January–March | 1 April |
| April | April–June | 1 July |
| May | April–June | 1 July |
| June | April–June | 1 July |
| July | July–September | 1 October |
| August | July–September | 1 October |
| September | July–September | 1 October |
| October | October–December | 1 January (next year) |
| November | October–December | 1 January (next year) |
| December | October–December | 1 January (next year) |
Worked example: 30 September vs. 1 October
A 30 September sitting falls in the July–September window, so the next window starts on 1 October. A 1 October sitting falls in the October–December window, so the next window starts on 1 January. Both examples assume the 12-month attempt cap and your board’s rules allow another sitting.
When the wait is longer: the three-in-12-months rule
If you have already sat three times in the last 12 months, the next attempt has to wait until it would not make four inside any 12-month period — in practice, 12 months after the first of the three. Example: attempts on 10 February, 12 May and 18 August mean the next is allowed from 10 February the following year, not in November.
Before you book the earliest date
- Results take 7–10 business days, so a sitting at the very end of a quarter leaves almost no time to see the result before the next window opens.
- Some boards need a new application or fee before each attempt. Check yours first.
- Each registration pays the full $225 NCEES fee, and an unused registration expires 12 months after approval.
- The earliest date is a limit, not a target. Pick the window your diagnostic report and weekly practice can support.

Frequently asked questions
How long do you have to wait to retake the FE exam?
Until the next quarterly testing window opens: anything from one day to about three months. NCEES allows one attempt per window and no more than three in any 12 months.
Can I retake the FE in the same month?
Only if the month spans two windows, which no month does. You need a date in the next calendar quarter.
I sat on 31 March. Can I sit again on 1 April?
Under NCEES policy, yes — 1 April is a new window. In practice your result may not have arrived yet, and booking without it is a guess.
Does my state board add a waiting period?
It can. NCEES says some boards are more restrictive than its policy, and some require their own application and fee. Check your board’s rules.
