SUCCESS!!
Question 1
In what decade did the field of laboratory animal science officially begin to develop?
A) 1920s
B) 1930s
C) 1940s
D) 1950s
E) 1960s
Correct Answer: C) 1940s
Rationale: Modern laboratory animal science as a distinct specialty began in the 1940s.
During this time, the need for standardized animal care and specialized knowledge in
research settings became apparent to ensure reproducible scientific results.
Question 2
What was the original name of the organization formed in 1950 that later became AALAS?
A) The Veterinary Technician Association
B) The Animal Care Panel (ACP)
C) The Society for Laboratory Animals
D) The Research Support Group
E) The Institute of Laboratory Animal Resources
Correct Answer: B) The Animal Care Panel (ACP)
Rationale: In 1950, Dr. Nathan Brewer and other veterinarians in the Chicago area formed
the Animal Care Panel (ACP) to discuss the care and management of laboratory animals.
This group eventually evolved into the American Association for Laboratory Animal
Science (AALAS) in 1967.
Question 3
Who is credited with leading the group that formed the Animal Care Panel (ACP) in 1950?
A) Dr. Henry Foster
B) Dr. Nathan Brewer
C) Dr. Simon Brimhall
D) Dr. Albert Sabin
E) Dr. Jonas Salk
Correct Answer: B) Dr. Nathan Brewer
Rationale: Dr. Nathan Brewer was a pioneer in laboratory animal medicine and was the
primary leader behind the formation of the ACP, which established the groundwork for
professional standards in the field.
Question 4
What does the acronym AALAS stand for?
A) American Association of Lab Animal Specialists
, Page 2
B) Association for the Advancement of Laboratory Animal Science
C) American Association for Laboratory Animal Science
D) Allied Association for Laboratory Animal Standards
E) Association of American Laboratory Animal Surgeons
Correct Answer: C) American Association for Laboratory Animal Science
Rationale: AALAS is the professional organization that serves as the bridge between
researchers, veterinarians, and technicians, providing education and certification for the
lab animal community.
Question 5
Which of the following is the entry-level AALAS certification for technicians?
A) LAT
B) LATG
C) CMAR
D) ALAT
E) RALAT
Correct Answer: D) ALAT
Rationale: The Assistant Laboratory Animal Technician (ALAT) is the first level of
certification provided by AALAS. It focuses on the fundamental concepts of animal
husbandry and facility operations.
Question 6
What are the three levels of AALAS technician certification in order from lowest to highest?
A) ALAT, LAT, CMAR
B) LAT, ALAT, LATG
C) ALAT, LAT, LATG
D) RALAT, RLAT, RLATG
E) Technician, Specialist, Technologist
Correct Answer: C) ALAT, LAT, LATG
Rationale: The three levels are Assistant Laboratory Animal Technician (ALAT),
Laboratory Animal Technician (LAT), and Laboratory Animal Technologist (LATG). Each
level requires increasing amounts of experience and education.
Question 7
The "R" in front of a technician's title (e.g., RALAT) indicates that the individual:
A) Is retired
B) Is part of the AALAS Registry
C) Is a research scientist
D) Is a resident veterinarian
E) Has reached the highest possible rank
Correct Answer: B) Is part of the AALAS Registry
Rationale: The Registry is a voluntary program where certified technicians document

ongoing professional development every two years. Registered status entitles the technician
to use the "R" prefix.
Question 8
Why are animal models primarily used in scientific research?
A) They are cheaper than using humans
B) They have similar physiological processes to humans
C) They do not require food or water
D) They are exempt from all federal laws
E) They are used only when computer models fail
Correct Answer: B) They have similar physiological processes to humans
Rationale: Animals are used as models because many of their physiological and biological
systems (like the circulatory or nervous systems) function similarly to those of humans,
allowing researchers to study diseases and treatments.
Question 9
Which of the following is considered an alternative to using live animal models?
A) Using a different species of animal
B) Cell culture techniques
C) Reducing the number of animals in a cage
D) Increasing the dose of a drug
E) Using younger animals
Correct Answer: B) Cell culture techniques
Rationale: Alternatives to live animals include "in vitro" methods such as cell and tissue
cultures, as well as computer modeling (in silico), which can sometimes replace the need for
an animal subject.
Question 10
In the research team, who is the person that plans and coordinates all phases of the research
work?
A) The Laboratory Animal Technician
B) The Laboratory Animal Veterinarian
C) The Principal Investigator (PI)
D) The Facility Manager
E) The Institutional Official
Correct Answer: C) The Principal Investigator (PI)
Rationale: The PI is the lead scientist responsible for the experimental design, obtaining
funding, and ensuring that the research is conducted according to the approved protocol.
Question 11
Which member of the research team is responsible for advising investigators on proper animal
model selection?
