Read your diagnostic report
Have your NCEES diagnostic report open. For each knowledge area, copy the number of items, slide to your score on the 0 to 15 scale, and mark where your solid line sits against the dashed line for passing examinees. No upload and no account; nothing you enter is saved or sent.
How close was I, and what do I study first?
Works from the three things on your report: items, your 0 to 15 score, and your bar against passing examinees.
Item counts start at the middle of the official range for each area. Replace them with the counts printed on your report. You can skip the slider and only mark the bars, or the other way round.
If you failed the FE or PE exam, the first question is usually painful and practical: how close was I?
The honest answer is that you can tell roughly how close you were and exactly where to work, but not the 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. Everyone who does not pass receives a diagnostic report showing relative strengths and weaknesses.
The Safe Interpretation
- Use the diagnostic report to decide what to study next.
- Do not turn the 0 to 15 scores into percentages or question counts. NCEES says they cannot be read that way.
- Weight each area by the number of items your report lists for it.
- 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.
The diagnostic report carries the same warning. Its cover note says the report cannot be used to determine the passing score, and that the number of questions you answered correctly cannot be determined from the scaled score. So any tool that tells you "you missed by 4 questions" or "you scored 52%" from a diagnostic report is inventing a number.
What the report does show
Each row of the report is one knowledge area, with three pieces of information:
- Number of items. How many questions that area carried on your exam.
- Your performance, 0 to 15. A scaled score. It lets you compare areas with each other and one attempt with the next. It is not a percentage.
- A bar against passing examinees. A solid line for you and a dashed line for the average of people who passed. NCEES notes the chart is not drawn to scale; it shows direction and rough distance.
NCEES's own sample report walks through the reading: areas well below the dashed line contributed to the result and need substantial study; areas a little below have room to improve; and when choosing between them, the number of items matters. In the sample, four areas a little below passing examinees held 26 questions and four areas well below held 18, so the larger group came first.
How the tool reads your report
The tool follows that same reasoning. Each area gets a weight: the number of items multiplied by how far it sat from passing examinees. Well below counts most, a little below counts half as much, and at or above counts very little. The 0 to 15 score only separates areas that carry the same mark. If you enter scores without marking the bars, the tool still orders your areas by score and items, but it holds back the closeness reading until at least 80% of your items are marked.
The study-hour figure is a budget from this site's study-hour model: the first-attempt hours for your time since school, plus 25% for a retake. PE retakes use about 250 hours.
Edge cases to handle carefully
- If you fill in only your three worst areas, the study order is incomplete. Fill every row.
- If every bar is marked at or above passing examinees, recheck the report. Diagnostic reports go only to people who did not pass.
- A "Close" reading does not mean NCEES made a mistake. The dashed line is an average of passers, not the pass line.
- Use the output to rank weak areas, not to argue that you "should have passed."
What each reading means
The reading comes from where your items sat, not from a hidden score. It is this site's summary, not an NCEES category.
| Reading | What your report looked like | Retake Move |
|---|---|---|
| Close | No items well below passing examinees, and at most about a third a little below. | Repair the areas a little below, then build a cushion with mixed timed sets. |
| Within reach | Up to about 12% of items well below. | Fix that small group first; it did most of the damage. |
| Clear gaps in specific areas | Roughly 12% to 35% of items well below. | Put at least half of the retake hours on the top areas. |
| Broad gap | More than about 35% of items well below. | Plan a full rebuild: diagnose, relearn by weight and weakness, mixed timed sets, final simulation. |
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. In the NCEES Squared 2025 FE discipline table, first-time pass rates for the disciplines supported in the app were Civil 61%, Electrical and Computer 64%, Environmental 67%, Mechanical 69%, Chemical 68%, and Other Disciplines 61%.
For supported PE tracks, the NCEES CBT pass-rate tables (year-round disciplines updated July 2026) reported Civil Transportation 61% first-time and 43% repeat, Civil Structural 62% and 43%, Civil Water Resources and Environmental 71% and 49%, Electrical Power 62% and 42%, and Electronics, Controls, and Communications 63% and 52%. Computer Engineering, updated once a year, remained 56% first-time on very low volume, so treat its repeat row 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
Do not work every low score equally. Start with areas that are both far from passing examinees and heavy in items.
- Many items, well below: first priority. These can move your next attempt fastest.
- Many items, at or above: protect the points with timed mixed practice.
- Few items, well below: repair after the larger areas 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.
Quick interpretation table
Use the table below as a fast check on a single row of your report.
| Diagnostic Signal | How to Treat It | Next Move |
|---|---|---|
| Well below the dashed line, 8 or more items | Priority repair area | Make this the first 1-2 week block and review misses by cause. |
| A little below the dashed line, 8 or more items | Likely near-line leak | Use targeted sets, then confirm with mixed timed questions. |
| Well below, 3 to 5 items | Second-tier repair | Fix it after the heavier areas unless it is quick. |
| At or just above the dashed line | Maintenance topic | Keep it warm with short mixed sets while repairing weaker areas. |
| Far above the dashed line | Protect the points | Do not over-study it unless timed practice shows a fresh gap. |
| Your score rose from one attempt to the next | Real progress | The 0 to 15 scale is built to compare attempts; keep doing what moved it. |
Write the item counts next to the bars before you plan. An area with 11 items a little below passing examinees is worth more study time than an area with 3 items well below.

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.
