- ASPRS has not published a verified official pass rate for the Certified Photogrammetric Technologist exam; treat any specific percentage you see with suspicion.
- Photogrammetry carries roughly 70% of the exam; five other domains carry roughly 6% each.
- You get two attempts per approved application, and a second failure means a new application and fees.
- The exam allows one bound reference, a handheld calculator, and scratch paper, so it is not unrestricted open-book.
What the Published Pass Rate Really Is (and Isn't)
If you searched for the pass rate of the ASPRS Certified Photogrammetric Technologist exam, here is the direct answer: no verified, official pass rate has been published that we can responsibly cite. Neither the ASPRS program page nor the certification manual dated June 2026 states a percentage of candidates who pass. This article therefore does something more useful than repeating a number of uncertain origin. It shows you what the available data does support, why a headline pass rate would be hard to interpret anyway, and how to build your preparation around the structural facts that actually predict outcomes.
A note on terminology before going further. "CPT" on this site refers to the ASPRS Certified Photogrammetric Technologist credential. It is not the Certified Photogrammetrist (CP) credential, which is the scientist-level designation from the same society, and it has no connection to other certifications that happen to share the three-letter acronym. If you are still orienting yourself, our explainers on what CPT certification is and what CPT stands for cover the basics.
Why No Reliable Number Exists Yet
Three structural reasons explain why a clean pass-rate figure is hard to produce for this credential.
A small, specialized candidate pool
Photogrammetry is a niche profession. The candidate pool is far smaller than for mass-market professional exams, and small pools produce volatile year-to-year percentages. Even if ASPRS did release a figure, a swing of a few candidates could move it noticeably.
Self-selection through experience requirements
Candidates must be approved before they can sit for the exam. That means years of documented experience, four references, and an ethics declaration have already filtered the field. A pass rate calculated on pre-qualified practitioners tells you something very different from a pass rate on an open-enrollment exam. You cannot compare the two honestly.
No published passing threshold or question count
We also could not verify a current numeric passing score or a current question count for the technologist exam. Without those, pass-rate commentary has nothing to anchor to. Older study guides written for the scientist-level credential may list question counts and scoring details, but those belong to a different exam and should not be assumed to apply here. For the current state of scoring information, see our page on the CPT passing score.
What the Official Sources Do Tell You
While the headline number is unavailable, the official materials describe a number of concrete facts that matter more to your preparation than a percentage would.
| Exam Feature | What the Sources State |
|---|---|
| Issuer | American Society for Photogrammetry and Remote Sensing (ASPRS) |
| Testing provider | Prometric, via test center or online remote proctoring |
| Format | Computer-based written technologist examination |
| Time limit | Two hours |
| Permitted materials | One bound reference, handheld calculator, writing device, scratch paper |
| Results | Reported immediately after the exam |
| Attempts | Two per approved application |
| Pass rate | Not verified or published |
Notice the two-hour limit combined with a single bound reference. That pairing rewards candidates who know where things are in their reference and can retrieve formulas quickly, rather than candidates who plan to learn the material during the exam. We cover the difficulty implications in how hard the CPT exam is.
How the Exam Is Built: The Matrix Behind Any Pass Rate
The most predictive data you can study is the official content matrix on page 33 of the ASPRS certification manual. The column for the technologist photogrammetry exam lists ten categories. Six carry positive allocations; four are published at 0%. ASPRS describes all allocations as approximate and notes that actual exam percentages may vary.
| Domain | Approximate Allocation |
|---|---|
| Photogrammetry | 70% |
| Mathematics | 6% |
| Earth Science | 6% |
| Engineering/Surveying | 6% |
| Physics | 6% |
| Professional/Ethical | 6% |
| Remote Sensing | 0% |
| GIS/LIS | 0% |
| Lidar | 0% |
| UAS | 0% |
The four 0% rows are retained here because they appear in the official matrix, not because they represent additional tested coverage. Practitioners who work heavily in lidar or UAS workflows sometimes assume those areas will be examined; the published matrix does not allocate any weight to them for this technologist exam. The full breakdown of each row is in our CPT exam domains guide.
Photogrammetry (about 70%)
This single domain decides most outcomes. A candidate who is strong everywhere else but shaky on photogrammetric fundamentals is statistically exposed, because the remaining five domains together account for roughly 30%.
- Expect questions rooted in the practical work of a photogrammetric technologist: imagery geometry, measurement, orientation concepts, and mapping production.
- Prioritize calculation fluency, since the permitted calculator signals that numeric problems are fair game.
- Index your one bound reference so photogrammetry formulas and tables are retrievable in seconds.
The Five 6% Domains
Mathematics, Earth Science, Engineering/Surveying, Physics, and Professional/Ethical each contribute roughly 6%. They are small individually, but together they make up the remaining positive allocation, and each is a plausible place to lose points if you ignore it.
- Mathematics: the quantitative foundation behind photogrammetric computation.
- Earth Science: the physical-world context that mapping depends on.
- Engineering/Surveying: control, measurement, and the surveying concepts that tie imagery to ground truth.
- Physics: the optical and radiometric principles underlying image formation.
- Professional/Ethical: conduct and professional responsibility, which connects to the ethics declaration required with your application.
Attempt Rules That Shape Who Passes
Because no pass rate is published, the attempt rules are the next best window into how the credential treats failure. The manual's provisions are specific:
- Approved applicants must take the examination within six months of approval.
- You are allowed two attempts per approved application.
- After an unsuccessful first attempt, one retake is permitted within six months of that attempt. An extension request is possible for extenuating circumstances.
- A second failure requires a brand-new application, new fees, and updated references.
- Prometric charges apply to the retake.
The built-in retake window also sets a natural study clock. If you fail the first attempt, you have a defined stretch to diagnose weaknesses and return. Since results are reported immediately, you leave the testing session already knowing the outcome and can begin that diagnosis the same day while your memory of the questions is fresh.
Who Sits for This Exam
The population taking the exam shapes any outcome statistics. According to the manual's detailed technologist section, applicants need three years of total experience, including at least two years in the specialty, plus four references and an ethics declaration. The application passes through review before you can schedule. Note that the program overview, the manual's introductory summary, and the October 2025 application describe the experience requirement differently, as three years of specialty experience. Because of that discrepancy, confirm your individual eligibility with ASPRS before paying anything. Our CPT requirements guide walks through the details.
Educational credit can reduce the experience needed by one-half year, but the manuals disagree on which degrees qualify: one page references an associate degree or higher, while an earlier table names bachelor's, master's, and doctoral degrees in engineering or the natural or physical sciences. Again, have ASPRS confirm how your degree and experience are counted.
The practical takeaway for a pass-rate discussion: the people who reach the exam room are working professionals with documented, referenced experience. Employers who hire for this credential, typically mapping firms, engineering and surveying consultancies, and government mapping programs, tend to value it as evidence of applied competence.

How to Read Pass-Rate Claims You Find Online
You will encounter confident percentages on forums, video descriptions, and aggregator sites. Use this checklist before trusting any of them.
- Check the credential. Does the source explicitly say ASPRS Certified Photogrammetric Technologist? Many do not, and some are describing an entirely different CPT.
- Check the level. Technologist and scientist-level (CP) credentials have different exams and different content columns. A figure for one does not transfer to the other.
- Check the source. A real figure should trace to ASPRS or Prometric. Anecdotal "I heard most people pass" is not data.
- Check the date. Even a legitimate figure from years ago may not reflect current exam content or current candidate pools.
Key Takeaway
Absence of a published pass rate is not a signal that the exam is easy or hard. It is simply a gap in public information. Base your confidence on the content matrix and your own practice results, not on a number nobody can source.
If you want a calibrated sense of readiness, the most honest measure available is performance on realistic practice questions weighted to the real matrix. You can begin with the CPT practice tests and track your results by domain.
Turning the Matrix Into a Preparation Plan
Since the pass rate cannot guide you, let the weighting guide you. Because photogrammetry dominates, the schedule below front-loads it and reserves later weeks for the smaller domains and a full-length rehearsal. Adjust the pacing to your own timeline; the sequence is the point. For a fuller approach, our CPT study guide goes deeper.
Photogrammetry foundations
- Rebuild core photogrammetric concepts and work calculation problems with your approved calculator.
- Decide which bound reference you will bring and begin tabbing the formulas and tables you expect to need.
Photogrammetry depth and the quantitative domains
- Continue photogrammetry practice, since it is about 70% of the exam.
- Cover Mathematics and Physics, which support the computation and image-formation questions.
Context domains
- Review Earth Science and Engineering/Surveying, focusing on how control and measurement connect imagery to ground positions.
- Read the Professional/Ethical material alongside the ethics declaration you signed.
Timed rehearsal
- Run a two-hour timed session using only the materials the exam permits.
- Check how fast you can retrieve answers from your bound reference, then re-tab it.
One caution on mock exams: because we could not verify a current official question count, do not assume a specific length when configuring a full-length simulation. Time-box the session to two hours and let the question count flex, and confirm the actual count with ASPRS or Prometric before exam day. Our CPT cheat sheet is a handy complement for last-week review, and you should confirm scheduling windows through our guide to CPT exam dates.
Frequently Asked Questions
No verified, official pass rate has been published by ASPRS for the Certified Photogrammetric Technologist exam. Any specific percentage you encounter should be checked against ASPRS or Prometric as a source; otherwise treat it as unreliable.
That cannot be determined from public data. Candidates are pre-screened through experience requirements, references, and an application review, so the pool is already filtered, which makes comparisons to open-enrollment exams misleading.
The manual permits two attempts per approved application. After a failed first attempt, one retake is allowed within six months, with an extension possible for extenuating circumstances. A second failure requires a new application, fees, and updated references.
Photogrammetry, at roughly 70% of the approximate allocation. Mathematics, Earth Science, Engineering/Surveying, Physics, and Professional/Ethical each carry roughly 6%. Remote Sensing, GIS/LIS, Lidar, and UAS are published at 0% for this exam.
Yes. The ASPRS program page reports immediate examination results, so you will know the outcome when you finish and can start planning a retake window right away if needed.
