The Land Surveyor in Training (LSIT) exam — administered by NCEES as the Fundamentals of Surveying (FS) examination — is the first licensure milestone for aspiring professional land surveyors in the United States. Passing the FS exam demonstrates foundational competence across mathematics, measurement science, boundary law, and modern surveying technology. Downloading a free printable LSIT practice test PDF gives you a portable, offline study resource you can use anywhere, from your desk to the field.
This PDF contains multiple-choice practice questions aligned to the NCEES FS exam specifications, covering traverse calculations, differential leveling, boundary principles, coordinate systems, and surveying instrumentation. Use it alongside the NCEES reference handbook and timed online practice sessions to build the speed and accuracy the exam demands.
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.
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.
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.
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.
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.
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.
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.
Printable PDFs are ideal for offline review, but combining them with timed digital practice maximizes your preparation. Our LSIT practice test delivers immediate scoring and answer explanations across all FS exam topic areas — traverse math, leveling, PLSS, coordinate systems, and boundary law. Repeated timed sessions help you internalize the NCEES Reference Handbook layout and build the calculation speed needed to complete all 110 questions within the 6-hour limit.
