CLARB

The L.A.R.E. is the licensure examination for landscape architects in the United States and Canada, administered by CLARB three times per year in two-week windows. It comprises four independent sections totaling 335 scored items plus 40 unscored pretest items, with 3.5 hours of seat time per section. Each section is scored separately and requires a scaled score of at least 650 to pass. Sections may be taken in any order and in any combination within an administration window. Retake limits and section-credit time limits are set by the licensing jurisdiction rather than by CLARB.

Sample LARE Practice Questions

Try these sample questions to review concepts for the LARE exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 210+ question experience with AI tutoring.

1What is the primary purpose of a topographic survey?
A.To establish legal property boundaries
B.To document existing elevations and surface features
C.To determine soil bearing capacity
D.To identify underground utilities
Explanation: A topographic survey documents existing elevations, contours, and surface features of a site. It is essential for understanding site drainage, identifying slopes, and planning grading operations. Property boundaries are established by boundary surveys, not topographic surveys.
2Which soil texture classification has the largest particle size?
A.Silt
B.Clay
C.Sand
D.Loam
Explanation: Sand particles range from 0.05 to 2.0 mm in diameter, making them the largest soil particles. Silt particles are smaller (0.002-0.05 mm), and clay particles are the smallest (less than 0.002 mm). Loam is a mixture of sand, silt, and clay.
3What is the primary function of a benchmark in surveying?
A.To mark property corners
B.To provide a known elevation reference point
C.To indicate building setback lines
D.To establish true north orientation
Explanation: A benchmark is a survey point with a precisely known elevation that serves as a reference for determining other elevations on a site. Benchmarks are essential for grading plans and ensuring accurate vertical control throughout a project.
4In the United States, which federal agency is primarily responsible for wetland identification and regulation?
A.EPA (Environmental Protection Agency)
B.USACE (U.S. Army Corps of Engineers)
C.USDA (U.S. Department of Agriculture)
D.USFWS (U.S. Fish and Wildlife Service)
Explanation: The U.S. Army Corps of Engineers (USACE) administers Section 404 of the Clean Water Act, which regulates discharge of dredged or fill material into waters of the United States, including wetlands. They are responsible for wetland delineations and permitting.
5What does the term "watershed" refer to?
A.A building designed to collect rainwater
B.The land area that drains to a common outlet
C.A water treatment facility
D.A flood control structure
Explanation: A watershed (also called a drainage basin or catchment area) is the area of land where all precipitation drains to a common outlet, such as a river, lake, or ocean. Understanding watershed boundaries is critical for hydrology and stormwater management.
6Which document establishes the legal boundaries of a property?
A.Topographic survey
B.Boundary survey
C.Site analysis diagram
D.Grading plan
Explanation: A boundary survey (also called a property survey or land survey) establishes property lines and corners. It identifies the exact legal boundaries of a parcel and is essential for determining buildable areas, setbacks, and easements.
7What is the standard slope requirement for accessible routes according to the ADA?
A.1:20 maximum (5%)
B.1:12 maximum (8.33%)
C.1:16 maximum (6.25%)
D.1:8 maximum (12.5%)
Explanation: ADA Standards require accessible routes to have a maximum slope of 1:20 (5%). Ramps may have steeper slopes up to 1:12 (8.33%) with specific requirements for landings, handrails, and edge protection.
8During the programming phase, what is a "space program"?
A.A schedule of construction activities
B.A document listing required spaces and their sizes
C.A zoning compliance analysis
D.A building maintenance schedule
Explanation: A space program is a document developed during the programming phase that lists all required spaces, their functions, sizes, and relationships. It translates client needs into quantifiable spatial requirements that guide design.
9What is the primary purpose of a site analysis diagram?
A.To show proposed construction details
B.To document existing site conditions and constraints
C.To calculate construction costs
D.To establish property boundaries
Explanation: A site analysis diagram documents existing site conditions including topography, vegetation, drainage patterns, sun/shade patterns, wind, views, and adjacent land uses. It synthesizes inventory data to inform design decisions.
10What is the purpose of a setback requirement in zoning?
A.To establish minimum distances from property lines to structures
B.To determine building height limits
C.To regulate parking requirements
D.To control building materials
Explanation: Setback requirements specify the minimum distance that structures must be located from property lines. They help ensure adequate light, air, privacy, and access for emergency services while creating consistent streetscapes.

LARE: Suggested Study Strategy

1Work directly from the CLARB exam blueprint; it lists every content area and task tested in each of the four sections
2Read the L.A.R.E. Orientation Guide before your first section so the hot spot and drag and place item types are familiar
3Practice contour interpolation, slope computation, and cut and fill calculations until they are automatic for Section 4
4Drill runoff estimation with the Rational Method and the NRCS curve number method, including time of concentration
5Practice reviewing grading and drainage plans for errors, since hot spot items ask you to locate the defect on a plan
6Learn the ADA and PROWAG numbers cold: 5.00% walk, 8.33% ramp, 2.08% cross slope, 30-inch maximum rise between landings
7Know CSI MasterFormat division assignments and the three-part SectionFormat structure for Section 3
8Review construction administration instruments and what each one does: RFI, ASI, proposal request, change directive, change order
9Study soil classification under both the USDA textural triangle and the Unified Soil Classification System, and know when each applies
10Understand the Clean Water Act permitting framework, including Sections 401, 402 and 404 and the one-acre NPDES threshold
11Take CLARB's official $25 practice exam for each section to calibrate pacing against the 3.5-hour seat time
12Remember that an in-exam calculator and electronic whiteboard are provided; no personal calculator or scratch paper is permitted
13Confirm your jurisdiction's eligibility, retake, and section-credit rules with your licensing board, since CLARB does not set them
14Join a study group; working scenario problems aloud exposes reasoning gaps that solo review does not

Frequently Asked Questions

What is the LARE exam pass rate?

CLARB publishes section-level pass rates for each administration through its exam results pages, and rates differ by section and by administration window rather than following a single fixed figure. Because each of the four sections is scored independently against a fixed standard, a candidate's result on one section does not affect the others. Check the current CLARB pass rate page for the most recent published figures rather than relying on third-party summaries.

How hard is the LARE exam?

The L.A.R.E. is a licensure examination built from a job task analysis of practicing landscape architects, so it tests applied judgment rather than recall. Section 1 covers inventory, analysis and project management; Section 2 covers planning and design; Section 3 covers construction documentation and administration; and Section 4 covers grading, drainage and stormwater management. Section 4 is the most calculation-intensive, requiring contour interpolation, slope and earthwork computation, runoff estimation, and drainage system sizing. CLARB does not publish a recommended number of study hours, so plan preparation by section using the exam blueprint.

What are the LARE exam requirements?

Eligibility to sit for the L.A.R.E. is determined by the licensing board in the jurisdiction where you intend to become licensed, not by CLARB. Most jurisdictions require a professional degree in landscape architecture from a program accredited by the Landscape Architectural Accreditation Board, or equivalent education, plus a specified amount of qualifying professional experience. All candidates must establish and maintain a CLARB Record to register for the exam, and some jurisdictions require CLARB to transmit your Record to the board for approval before you may register.

In what order should I take the LARE sections?

CLARB allows the four sections to be taken in any order, and you may attempt more than one section during a single two-week administration window. Many candidates begin with the section closest to their current daily practice, since applied experience is the strongest preparation. Because Section 4 (Grading, Drainage and Stormwater Management) is the most calculation-intensive, candidates who do not perform technical grading and drainage work regularly often allow additional preparation time for it regardless of where they place it in the sequence.

How long do I have to complete all four LARE sections?

CLARB does not impose a single universal time limit for completing all four sections. Retake limits and the length of time a passed section remains valid are set by the licensing jurisdiction, so you should confirm the rule with the board where you intend to become licensed. Separately, CLARB periodically updates the exam blueprint following a job task analysis; candidates who have not completed all sections before a blueprint transition may be required to take additional sections or repeat content under the updated structure.

What is the difference between the four LARE sections?

Section 1, Inventory, Analysis and Project Management, carries 90 scored items covering project management, inventory and data collection, stakeholder engagement, physical analysis and contextual analysis. Section 2, Planning and Design, carries 85 scored items covering stewardship and design principles, master planning, schematic design and design development. Section 3, Construction Documentation and Administration, carries 90 scored items covering construction plans and details, specifications and bidding, and construction administration. Section 4, Grading, Drainage and Stormwater Management, carries 70 scored items covering stormwater management, grading and earthwork, and drainage systems. Each section adds 10 unscored pretest items and allows 3.5 hours of seat time.

How much does the LARE exam cost?

Each L.A.R.E. section costs $535, so all four sections total $2,140. Candidates must also establish and maintain a CLARB Record, which costs $175 for the initial candidate Record and $165 for annual candidate maintenance. Retaking a failed section costs the full $535 section fee again. CLARB also offers an optional practice exam for each section at $25. Cancelling by an administration's cancellation deadline refunds the section fee minus the cancellation fee in CLARB's published fee schedule; requests after that deadline are not refunded, and registrations cannot be transferred or rescheduled to a later administration. Jurisdiction application and licensing fees are separate and vary by board.

What study materials should I use for the LARE?

Start with CLARB's own free resources: the exam blueprint, which lists every content area and task tested in each section, and the L.A.R.E. Orientation Guide, which explains the item types (multiple choice, multiple response, hot spot, and drag and place), testing protocols, and the reference information supplied during the exam. CLARB also sells a practice exam for each section at $25. Commonly used reference texts include Site Engineering for Landscape Architects, Landscape Architectural Graphic Standards, and Time-Saver Standards for Landscape Architecture. Focus on applying concepts to site scenarios rather than memorizing definitions.
