What is the difference between the LSIT and the FS exam?

LSIT (Land Surveyor in Training) is the credential you earn after passing the NCEES Fundamentals of Surveying (FS) exam. The FS exam is the actual test administered by NCEES; LSIT is the designation most states award to candidates who pass it. Some states use slightly different terminology, but in nearly all jurisdictions passing the FS exam is the first step toward full Licensed Land Surveyor (LS or PLS) licensure.

Can I use a calculator and reference materials during the LSIT exam?

Yes. NCEES provides the FS Reference Handbook digitally during the exam — it is also available as a free download on the NCEES website so you can practice with it beforehand. NCEES maintains an approved calculator list; only calculators on that list are permitted in the exam room. Knowing how to navigate the Reference Handbook quickly is a major time-saving advantage.

How many questions are on the LSIT (FS) exam and how long does it take?

The NCEES FS exam contains 110 multiple-choice questions administered in a single 6-hour session at a Pearson VUE testing center. There is no separate morning/afternoon split — all 110 questions are presented in one continuous block. The exam is computer-based, so you can flag questions for review and return to them before the session ends.

What score do I need to pass the LSIT exam?

NCEES uses a scaled scoring system and sets the passing score after each exam administration using a standard-setting process. The passing score is reported on a scale and is not a simple percentage. NCEES does not publish a fixed cut score in advance, but historically a solid understanding of all six exam domains — especially traverse calculations, leveling, and boundary law — is sufficient for most candidates who prepare thoroughly.

What the LSIT / FS Exam Covers

The NCEES FS exam blueprint spans six broad knowledge areas. Every question on the exam can be answered using the NCEES FS Reference Handbook, so knowing where to find formulas quickly is as important as understanding the concepts.

Mathematics and Statistics

Trigonometry is the backbone of surveying calculations. Expect questions on solving oblique triangles, applying the law of sines and cosines, computing inverse tangents for bearings, and propagating errors through calculated values. Least squares adjustment basics — understanding how residuals and redundant observations improve accuracy — appear on more advanced questions. Significant figures and unit conversions are tested throughout.

Horizontal Control: Traverse Calculations

Closed and open traverse calculations are a major exam focus. You must be able to convert between bearings and azimuths, compute latitudes and departures (latitude = distance × cos(bearing), departure = distance × sin(bearing)), calculate closure error and precision ratio, apply the compass (Bowditch) rule for distributing closure error, and compute final coordinate values for each traverse station. Coordinate geometry — computing the area of a polygon using the coordinate method — is also heavily tested.

Vertical Control: Differential Leveling

Differential leveling questions require computing foresight and backsight readings, calculating height of instrument (HI), determining bench mark elevations, and identifying allowable closure errors. Trigonometric leveling (using vertical angles and slope distances to determine elevation differences) appears on higher-difficulty questions. Rod reading interpolation and digital level operation are also tested.

Boundary Surveying and Legal Principles

The PLSS (Public Land Survey System) section tests township and range descriptions, section numbering (1–36 within a township), and aliquot part descriptions. Metes and bounds descriptions require understanding calls for course (bearing + distance), calls for monuments, and calls for adjoiner. Legal principles include senior vs. junior rights (older deed controls over newer), adverse possession elements, and easement types (express, implied, prescriptive). Riparian rights for water boundaries are also tested.

Map Projections and Coordinate Systems

Candidates must understand the difference between NAD83 and NAD27 datums, UTM zone structure and coordinate format, and state plane coordinate system zones. Conversion between geographic coordinates (latitude/longitude) and grid coordinates appears on the exam. Photogrammetry basics — flight line overlap requirements (60% forward, 30% side lap), scale of a vertical photograph (f/H where f = focal length, H = flying height above datum), and stereoscopic viewing — round out this section.

Surveying Equipment and Technology

Total station operation (measuring horizontal and vertical angles, slope distances, and computing coordinates via data collector), GPS/GNSS principles (satellite geometry, PDOP, RTK vs. static methods, multipath error), and automatic level operation (rod readings, collimation error) are all tested. Understanding instrument error sources and field correction procedures demonstrates practical competency.
