CST Passing Score 2026: Exactly What You Need to Pass

TL;DR
  • The normal passing criterion for Certified Survey Technician Level I is 70%, though the CST Board may adjust it for a cycle.
  • Scores of 66-69 are held for cycle review; 65 or below is a fail.
  • The exam is 200 multiple-choice questions in 4 hours, open book, so 70% means roughly 140 correct answers.
  • Field Equipment & Operations carries 75 questions and Survey Computations 50, together more than half the exam.

The Number: 70% and What Sits Around It

If you are searching for the CST passing score, here is the direct answer for the Certified Survey Technician Level I exam from the National Society of Professional Surveyors (NSPS): the normal passing criterion is 70%. That figure is subject to adjustment by the CST Board, which means the threshold is a standing benchmark rather than a promise carved in stone for every testing cycle.

Three score bands appear on the NSPS results page, and understanding all three matters more than memorizing the headline number:

Score BandOutcomeWhat It Means
70% or higherPass (normal criterion)You meet the standard passing criterion, subject to Board adjustment.
66-69%Pending cycle reviewYour result is not final until the Board reviews the cycle.
65% or belowFailYou did not meet the criterion; retake rules apply.

The exam is administered by the Certified Survey Technician Board (CSTB) through approved proctors, and it is the shared entry-level Level I examination. Level I requires no experience and NSPS membership is not required, so the score is the only gate between you and the credential. For a broader look at eligibility, see our guide to CST requirements.

The 66-69 Gray Zone Explained

Most certification exams give you a binary result. The Level I exam adds a middle category: scores from 66 through 69 are marked as pending cycle review. That is the part candidates misunderstand most often.

Do not plan around the gray zone: A pending result means the outcome is undecided, not that you passed. The Board can adjust the criterion for a cycle, but nothing published tells you which way a pending score will land. Treat 70% as your real target and consider any result below it as uncertain.

Practically, this changes how you should study. A candidate aiming for "just enough" at 68% is aiming at a result that depends on a decision outside their control. Build your preparation so that your practice scores sit comfortably above 70%, not hovering at the edge of the review band.

Translating the Percentage Into Questions

The exam has 200 multiple-choice questions. Taking the 70% criterion at face value, you need roughly 140 correct answers, which leaves about 60 questions you can miss. The 66-69 band corresponds to roughly 132 to 138 correct answers on a 200-question exam, and 65% or below is 130 correct or fewer. These are straightforward arithmetic conversions of the published percentages, not separate official cut scores.

With 4 hours for 200 questions, you have an average of about 72 seconds per question. That pace is manageable for definition and recognition items, but computation questions and anything requiring you to look something up in a reference will consume more than their share. Budgeting your time is part of earning the score.

Questions are multiple choice, delivered in English only, either online or on paper with an approved on-site proctor. There is no published partial-credit scheme to worry about; each question is right or wrong. If you want a sense of how demanding that is in practice, read how hard the CST exam really is.

Where the Points Live: Six Work Elements

NSPS publishes question allocations for each work element, not percentage weights. That distinction is worth respecting: the counts below are the official numbers, and any percentages you see elsewhere are derived rather than published. Here is how the 200 questions are distributed.

Work ElementNumber of Questions
Field Equipment & Operations75
Survey Computations50
Office Operations, Plan Reading and Preparation34
First Aid & Safety20
Survey Types and History15
Survey Control6

The two heaviest elements, Field Equipment & Operations (75) and Survey Computations (50), add up to 125 of the 200 questions. If you are weak in either, no amount of strength in the smaller elements will rescue a 70% result. Our complete guide to all six CST content areas walks through each one in more depth.

Field Equipment & Operations (75 questions)

The largest element and the one most tied to real field work. Expect questions on how instruments are set up, used, checked, and cared for, and how field procedures are carried out correctly.

  • Instrument setup, leveling, and operating procedures
  • Field routines and equipment handling
  • Recognizing correct versus incorrect field practice

Survey Computations (50 questions)

This is where calculator rules and unit fluency decide scores. Candidates who treat this as a reference-lookup section often run out of time.

  • Working through survey math accurately and quickly
  • Unit conversions, using the conversion charts in your fundamental surveying text
  • Practicing on a permitted calculator you already know well

Office Operations, Plan Reading and Preparation (34 questions)

Reading and interpreting survey documents and understanding how field data becomes finished drawings and plans.

  • Interpreting plan information correctly
  • Understanding how office work supports field work

First Aid & Safety (20 questions)

Twenty questions is a meaningful block. A first-aid and safety manual appears on the recommended reference list for good reason, and these items reward straightforward preparation.

Survey Types and History (15) and Survey Control (6)

Smaller blocks, but every question counts toward 140. Survey Control has only 6 questions, so it should not consume disproportionate study time, while Survey Types and History rewards vocabulary and definitions. The recommended reference Definitions of Surveying and Associated Terms is directly relevant here.

Open Book Does Not Mean Easy

The exam is open book. Printed references and securely bound technical notes are permitted, but resource sharing and access to network storage, email, or the internet are prohibited under the Online Exam Proctor Packet. For online delivery, that means your allowed materials are physical and bound, not a browser tab.

The open-book trap: With 200 questions and about 72 seconds each, you cannot look up every answer. References help most when you already know where things are. Tab your fundamental surveying text, mark the conversion charts, and organize notes by work element so a lookup takes seconds, not minutes.

NSPS recommends a fundamental surveying text with conversion charts, a first-aid/safety manual, and Definitions of Surveying and Associated Terms. The CST Flipchart is included with your fee and supplied on exam day, so learn how it is organized beforehand rather than meeting it for the first time during the test.

Calculator rules that can cost you points

Under the dedicated calculator policy effective October 25, 2022, only these families are permitted: Casio fx-115 and fx-991, HP 33s and 35s, and TI-30X and TI-36X. Some older FAQ language is broader, but the dedicated policy page is the one to follow. Bring a permitted model, know its functions cold, and do not discover on exam day that your calculator is not allowed. See our CST study guide for how to build calculator fluency into your prep.

If You Miss: Retake and Cycle Rules

A failing score is not the end, but there are rules and costs. A same-level retake within one year costs USD 150 for individuals or USD 100 for students, active military, and veterans. The initial exam fee is USD 180 for individuals or USD 120 for those discounted categories. For the full picture, including group pricing questions, see our CST certification cost breakdown.

  • The FAQ requires you to wait for a complete cycle before retesting.
  • After three consecutive failures, the July 2024 Program Book requires documented education in the failed work elements before a fourth attempt.
  • Your retake fee depends on timing, so check that you are inside the one-year window.

The practical lesson: your first attempt is the cheapest and fastest path. Scheduling also affects this, since online availability is restricted to weekdays and the second Saturday monthly on the fee and setup pages, while one older proctor packet says any date. Confirm your actual appointment with NSPS and your proctor. Our CST exam dates guide covers scheduling details.

Reading Pass Statistics Without Fooling Yourself

Candidates often try to infer the "real" difficulty of the passing score from pass-rate data. The only historical data point available is from the NSPS CST Board Fall 2023 Final Minutes, which record 61 Level I passes and 35 failures in quarter-grading. That is a historical cohort, not a current annual pass rate and not a first-time pass rate.

Why this matters: A single grading cohort can include retakers, and the minutes do not break out first-timers. Using it to predict your own odds is unreliable. Focus on hitting the 70% criterion by domain rather than on a headline rate. We explore this more in what the CST pass-rate data actually shows.

A Score-Driven Plan Built Around the Domains

Because the score is driven by question counts, let allocation shape your calendar. Here is a sample sequence that front-loads the heavy elements. Adjust the length to your own timeline.

Week 1-2

Field Equipment & Operations

  • Work through your fundamental surveying text on instruments and procedures
  • Tab references you plan to bring
Week 3-4

Survey Computations

  • Drill problems on your permitted calculator daily
  • Master conversion charts and unit handling
Week 5

Office Operations, Plan Reading and Preparation

  • Practice reading plans and interpreting data
Week 6

First Aid & Safety, Survey Types and History, Survey Control

  • Review safety manual and key terms
  • Take a full timed practice exam and score yourself against 70%

Official samples are illustrative and should not be your only resource. The NSPS Level 1 Sample Examination corroborates the six work elements, but its cover says January 2024 and its internal headings retain January 2023, so treat it as a format guide rather than proof of a new 2026 blueprint. Supplement it with a broader CST practice test bank and the CST cheat sheet for fast review.

After You Pass: Renewal and What the Credential Is

Passing earns the Certified Survey Technician Level I credential, which is distinct from a surveying license; it does not replace the NCEES Fundamentals of Surveying licensure pathway. Renewal is USD 40 annually, and continuing education became mandatory with July 2026 renewal. The renewal notice specifies Level I as "2 CEUs annually" while describing the amounts as hours, and the 2023 Board minutes use two hours, so confirm the exact unit with NSPS when you renew.

Reinstatement fees are also inconsistent across sources: the FAQ lists USD 50 per missed year for up to three years, while the July 2024 Program Book lists USD 10. Verify any reinstatement invoice directly with NSPS. If you are weighing the credential's value, our ROI analysis and salary guide help; note that the Bureau of Labor Statistics reports a May 2025 median of USD 54,240 for surveying and mapping technicians generally, which is not a measure of CST holders' pay.
