Sample CLARB - Council of Landscape Architectural Registration Boards Practice Questions
Try these questions from our free CLARB - Council of Landscape Architectural Registration Boards practice tests. The correct answer and an explanation follow each question.
A landscape architect holds a license in one state. A long-time client acquires property in a neighboring state and asks the landscape architect to prepare and seal a set of construction drawings for a new park. The landscape architect is not licensed in the neighboring state. Which of the following is the most appropriate course of action?
- A. Perform the work and apply the out-of-state seal, noting the project's actual location.
- B. Complete the drawings but deliver them without a professional seal, as the client is a long-term partner.
- C. Associate with a landscape architect who is licensed in the project state to review and seal the drawings.
- D. Apply for a temporary project exemption from the neighboring state's licensing board.
Answer: C. Associate with a landscape architect who is licensed in the project state to review and seal the drawings.
It is illegal and unethical to practice landscape architecture or use a professional seal in a jurisdiction where one is not licensed. [18] The proper professional procedure is to collaborate with a locally licensed professional who can take legal responsibility for the work by reviewing it for compliance with local regulations and applying their seal. This ensures the public's health, safety, and welfare are protected under that state's laws.
A landscape architect is specifying materials for a large project. A representative from a stone quarry offers the landscape architect an all-expenses-paid trip to tour their facilities. According to the ASLA Code of Professional Ethics, what is the landscape architect's primary obligation in this situation?
- A. Accept the trip, as it is a standard industry practice for product education.
- B. Disclose the offer in writing to the client and seek their direction before proceeding.
- C. Decline the offer but ensure the quarry's products are specified to maintain a good relationship.
- D. Accept the trip but do not disclose it to the client to avoid complicating the project.
Answer: B. Disclose the offer in writing to the client and seek their direction before proceeding.
The ASLA Code of Professional Ethics requires members to avoid conflicts of interest or the appearance of such conflicts. Accepting a valuable gift from a supplier could be perceived as influencing professional judgment. [24] The core ethical mandate is transparency; the professional must fully disclose such offers to the client, allowing the client to make an informed decision about the potential conflict. [24]
Which of the following drawings in a landscape architecture construction set provides the most detailed information on material connections, dimensions, and assembly of a specific site element like a custom bench or pergola?
- A. Layout Plan
- B. Grading and Drainage Plan
- C. Details and Sections
- D. Planting Plan
Answer: C. Details and Sections
Details and Sections are large-scale drawings that magnify specific, complex portions of the project to show how different components and materials are to be assembled. They provide critical information for the contractor to build the element correctly.
A CLARB exam scenario asks how to minimize light pollution from a new park lighting system. Which approach is most appropriate?
- A. Use full-cutoff luminaires aimed downward with motion sensors and warm color temperature LEDs
- B. Install the tallest poles possible to spread light widely
- C. Use upward-facing spotlights on trees and structures
- D. Maximize lumen output to ensure safety at all hours
Answer: A. Use full-cutoff luminaires aimed downward with motion sensors and warm color temperature LEDs
Full-cutoff fixtures direct light only downward, eliminating sky glow and glare, while motion sensors reduce unnecessary nighttime illumination and dark-sky LEDs minimize ecological disruption.
