LARE Study Tips from Top Performers

1Start with Section 1 or 2 if you're early in your career - they cover broader, more foundational knowledge
2Use CLARB's official content outlines - they define exactly what topics are tested on each section
3Section 4 requires strong math skills - practice earthwork, slope, and drainage calculations extensively
4Study grading fundamentals - understanding contours, spot elevations, and cut/fill is critical for Section 4
5Practice stormwater calculations including the Rational Method and time of concentration
6Review construction drawing types and how to read plans, sections, and details for Section 3
7Understand CSI MasterFormat and specifications writing for Section 3
8Study plant identification and regional vegetation for site inventory questions
9Know ADA accessibility requirements for routes, ramps, and parking
10Understand soil classification, compaction, and drainage properties
11Review construction administration processes including submittals, RFIs, and change orders
12Take CLARB's official practice exams to understand question formats and timing
13Join a study group with other candidates - the LARE is challenging and peer support helps
14Allocate 80-120 study hours per section depending on your experience and technical background

Frequently Asked Questions

What is the LARE exam pass rate?

Pass rates for the LARE vary by section. Section 1 (Project Management & Site Analysis) typically sees pass rates of 55-65%. Section 2 (Planning & Design) has pass rates around 50-60%. Section 3 (Construction Documentation & Administration) sees pass rates of 55-65%. Section 4 (Grading, Drainage & Stormwater Management) is typically the most challenging with pass rates of 45-55%. Overall, well-prepared candidates who complete comprehensive study programs pass at higher rates. Most candidates require 2-3 attempts to pass all four sections.

How hard is the LARE exam?

The LARE is considered challenging, particularly Section 4 which tests technical grading and drainage calculations. Section 1 focuses on project management and site analysis. Section 2 tests design principles and planning. Section 3 covers construction documentation. Section 4 requires proficiency in earthwork calculations, slope analysis, stormwater runoff calculations, and drainage system design. Most successful candidates study 80-120 hours per section over 2-3 months. Section 4 typically requires the most preparation time due to the mathematical calculations and technical nature of the content.

What are the LARE exam requirements?

To take the LARE, you generally need: (1) education - a bachelor's or master's degree in landscape architecture from an LAAB-accredited program (or equivalent through the LAAB alternate path), (2) work experience - completion of the Council of Landscape Architectural Registration Boards (CLARB) Council Record with verified experience, typically requiring 1-4 years of professional experience depending on your state's requirements, and (3) approval from your state licensing board to sit for the exam. Requirements vary by state, so check with your specific state board for exact requirements.

In what order should I take the LARE sections?

While you can take sections in any order, many candidates start with Section 1 or Section 2 as they cover broader knowledge areas. Section 1 (Project Management & Site Analysis) covers fundamental concepts. Section 2 (Planning & Design) tests design principles and planning knowledge. Section 3 (Construction Documentation) requires understanding of technical drawings and specifications. Section 4 (Grading/Drainage) is often taken last as it is typically the most challenging and requires strong technical skills. Consider your strengths - if you're strong in technical calculations, you might tackle Section 4 earlier.

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

You have a 5-year rolling window to pass all four sections from the date you pass your first section. This means if you pass Section 1 in 2026, you have until 2031 to pass the remaining three sections. If you don't pass all sections within 5 years of your first pass, that first section will expire and you'll need to retake it. There's no limit to how many times you can retake failed sections. CLARB recommends completing all sections within 2-3 years while your knowledge and exam preparation skills are fresh.

What is the difference between the four LARE sections?

Section 1 (90 items, 3.5 hours) tests project management, site inventory and analysis including topography, soils, climate, hydrology, and vegetation. Section 2 (95 items, 3.5 hours) tests planning and design principles, circulation, utilities, and stormwater management. Section 3 (100 items, 3.5 hours) tests construction documentation including drawings, specifications, and construction administration. Section 4 (105 items, 4 hours) tests grading, drainage, and stormwater management including calculations, earthwork, and technical drainage design.

How much does the LARE exam cost?

The LARE costs $535 per section, totaling $2,140 for all four sections. This is in addition to CLARB Council Record fees (approximately $400-600 depending on when you start) and state licensing board fees which vary by jurisdiction. Some states also require additional exams or fees beyond the LARE. If you need to retake a section, you pay the full $535 fee again for that section. There may be additional fees for rescheduling or changing test centers.

What study materials should I use for the LARE?

CLARB provides official LARE Reference List and Content Outlines as primary resources. Recommended materials include: (1) Landscape Architectural Graphic Standards, (2) Site Engineering for Landscape Architects, (3) Time-Saver Standards for Landscape Architecture, (4) Landscape Architecture: A Manual of Environmental Planning and Design, (5) Grading and Earthwork calculations references, (6) Construction Specifications and drawings references. CLARB offers practice exams for each section. Many candidates also use commercial study programs and join LARE study groups. Focus on understanding the application of concepts rather than just memorization.
