If you failed the FE or PE exam, the first question is usually painful and practical: how close was I?

The honest answer is: you can estimate a retake plan, but you cannot calculate the exact number of questions you missed by. NCEES says exam results are pass/fail, raw correct answers are converted to scaled scores, and the passing score is not published. NCEES also provides diagnostic reports to show relative strengths and weaknesses after an unsuccessful attempt.

The Safe Interpretation

  • Use the diagnostic report to decide what to study next.
  • Do not treat it as an exact raw-score or pass/fail converter.
  • Weight each topic by how many questions it can represent on the exam blueprint.
  • Build a cushion before retesting, especially if you were near the line.

Why nobody can give you the exact gap

NCEES scoring is not a simple public percentage. The official scoring page explains that the number of correct answers is converted to a scaled score, adjusted for small differences in exam form difficulty, and compared with a minimum ability level set through psychometric methods. NCEES also states that it does not publish the passing score.

That means a diagnostic importer should say "you appear close" or "your highest-impact repair topics are..." It should not say "you missed by exactly 4 questions" as if it had access to the scoring model.

A better way to ask the question

Instead of asking for an exact pass line, ask: "How much repair work do I need before a retake is rational?" That is something your diagnostic can help answer.

  1. Enter each diagnostic topic score.
  2. Enter the item count from the diagnostic report when it is available.
  3. Map topics without item counts to the official exam blueprint ranges.
  4. Convert each topic to a rough percent-equivalent score.
  5. Weight weak topics by reported item count or by a conservative blueprint-range estimate.
  6. Use the result to choose a 2, 4, 6, 8, or 12 week reset plan.

How the estimate is calculated

The app is deliberately conservative. If your diagnostic report lists the number of items in a knowledge area, that item count gets used as the topic weight. If you leave item counts blank, the app uses the current NCEES blueprint range and shows a planning range instead of pretending the exact mix is known.

For example, if a topic can represent 10-15 questions, a low score in that topic is treated as higher impact than a low score in a 4-6 question topic. But the app still cannot know which items were scored, which items were pretest, how the scaled-score conversion moved the result, or the official cut score for that exam form.

Edge cases to handle carefully

  • If you enter only the three failed categories and leave everything else blank, the estimate is incomplete.
  • If every category is entered as perfect but the official result was fail, the entries or assumptions are inconsistent. Trust the official result and re-check the report.
  • If the weighted index is above the planning target but you still failed, that does not mean NCEES made a mistake. The diagnostic scale is not a raw-score report.
  • Use the output to rank weak areas, not to argue that you "should have passed."

The planning bands we use

Inside the app, the Diagnostic Retake Planner uses a conservative 70% raw-equivalent planning target. That target is not the NCEES passing score. It is simply a practical buffer target for study planning, and the app displays a range when the exact topic item counts are unknown.

Use pass rates as context, not destiny

Pass rates are useful for setting expectations, but they do not tell you what will happen on your next attempt. NCEES reported January 2026 FE pass rates for first-time examinees from EAC/ABET programs within 12 months of graduation. Supported FE rates in the app include Civil 63%, Electrical and Computer 69%, Environmental 68%, Mechanical 72%, Chemical 68%, and Other Disciplines 61%.

For supported PE tracks, the NCEES CBT pass-rate table updated in January 2026 reported Civil Transportation 55% first-time and 42% repeat, Civil Structural 58% and 37%, Civil Water Resources and Environmental 68% and 47%, Electrical Power 57% and 39%, and Computer Engineering 56% first-time. The Computer Engineering repeat row had very low volume, so treat it carefully.

Historical pass rates can be useful background research, especially when an exam has changed specifications or has a small testing population. They still should not be used as an individual pass predictor. Your own topic scores, practice accuracy, timing, and reference-navigation reliability are better inputs for deciding when to retest.

What to do with your top three weak areas

Once the diagnostic is weighted, do not work every low score equally. Start with topics that are both weak and high weight.

  • High weight, low score: first priority. These can move your next attempt fastest.
  • High score, high weight: protect the points with timed mixed practice.
  • Low score, low weight: repair after the larger topics unless it is a fast fix.
  • Conceptual misses: rebuild the setup, not just the final formula.
  • Lookup misses: practice reference navigation until it is part of the solve.

Free mini diagnostic worksheet

This public worksheet is intentionally lighter than the app planner. It will not save your diagnostic, calculate a full weighted schedule, or adapt a calendar, but it gives you a cautious first read without needing a license.

If your diagnostic report lists item counts by knowledge area, write those next to the 0-15 bars. If it does not, treat weak high-weight blueprint ranges as the first risk to repair, not as a precise pass/fail conversion.

Frequently Asked Questions

Can I calculate exactly how close I was to passing?

No. You can build a reasonable study estimate, but not an exact NCEES pass-score conversion. The diagnostic is best used to prioritize the retake plan.

Should I retake immediately if the estimate says I was close?

Only if the weak-topic causes are understood and fixed. Near-line candidates often need a cushion, not just another attempt with the same habits.
