AALAS Assistant Laboratory Animal Technician (ALAT) Chapter 1: Introduction to
Laboratory Animal Science.Exam Questions and Answers Practice Questions
with Solutions Newest | Already Graded A+

Question 1
In what decade did the field of modern laboratory animal science officially begin?
A) 1920s
B) 1930s
C) 1940s
D) 1950s
E) 1960s
Correct Answer: C) 1940s
Rationale: While animals have been used in research for centuries, laboratory animal
science as a specialized organized field began in the late 1940s to ensure standardized care
and healthy models for research.

Question 2
What was the original name of the organization formed in 1950 by Dr. Nathan Brewer and his
colleagues?
A) American Association for Laboratory Animal Science (AALAS)
B) National Institutes of Health (NIH)
C) Animal Care Panel (ACP)
D) Laboratory Animal Welfare Group (LAWG)
E) Institute for Laboratory Animal Research (ILAR)
Correct Answer: C) Animal Care Panel (ACP)
Rationale: The Animal Care Panel (ACP) was established in 1950 to define good husbandry
practices and establish the foundation of the laboratory animal science profession. It was
renamed AALAS in 1967.

Question 3
The ACP was renamed in 1967 to become which professional organization?
A) ASLAP
B) AALAS
C) ACLAM
D) NABR
E) AVMA
Correct Answer: B) AALAS
Rationale: The Animal Care Panel changed its name to the American Association for
Laboratory Animal Science (AALAS) in 1967 to reflect its national role and scope in the
scientific community.

Question 4
AALAS is an acronym that stands for:
A) American Association of Laboratory Animal Science

, Page 2

B) Associated Agency for Lab Animal Specialists
C) American Academy of Lab Animal Surgeons
D) Animal Associated Laboratory and Science
E) Allied Association of Laboratory Animal Services
Correct Answer: A) American Association of Laboratory Animal Science
Rationale: AALAS is the primary professional organization for individuals and institutions
in the laboratory animal science field, providing education, certification, and advocacy.

Question 5
Which of the following is the first level of AALAS technician certification?
A) LAT
B) LATG
C) ALAT
D) RLAT
E) RALAT
Correct Answer: C) ALAT
Rationale: The Assistant Laboratory Animal Technician (ALAT) is the entry-level
certification. It focuses on the basics of husbandry, sanitation, and safety.

Question 6
Which certification level is the intermediate level for laboratory animal technicians?
A) ALAT
B) LAT
C) LATG
D) CMAR
E) VMD
Correct Answer: B) LAT
Rationale: The Laboratory Animal Technician (LAT) is the middle level of certification,
requiring more experience and knowledge of physiology and technical procedures than the
ALAT.

Question 7
What is the highest level of AALAS technician certification?
A) ALAT
B) LAT
C) LATG
D) RALAT
E) CMAR
Correct Answer: C) LATG
Rationale: The Laboratory Animal Technologist (LATG) is the highest of the three
technician certification levels, requiring extensive knowledge of management, facility
operations, and advanced science.

Question 8
What is the primary reason that animals are used in biomedical research?
A) They are less expensive than computers
B) Their biological systems are very similar to humans
C) They do not feel pain like humans do
D) There are no laws preventing their use
E) They reproduce faster than cell cultures
Correct Answer: B) Their biological systems are very similar to humans
Rationale: Animals, particularly mammals, share similar organs, systems (nervous,
endocrine, immune), and DNA with humans, making them effective "models" to study
diseases and treatments.

Question 9
Which of the following is considered an alternative to using animal models in research?
A) Using healthy humans instead
B) Computer mathematical models
C) Skipping safety trials
D) Using only wild-caught animals
E) Relying solely on historical data
Correct Answer: B) Computer mathematical models
Rationale: Research ethics require scientists to look for alternatives to animal use.
Mathematical computer models and in-vitro cell cultures are primary alternatives.
Question 10
Cell culture techniques are an example of what type of research alternative?
A) Refinement
B) Reduction
C) Replacement
D) Redundancy
E) Replication
Correct Answer: C) Replacement
Rationale: Using cell cultures instead of living animals is a form of "Replacement," which is
one of the 3Rs of research ethics (Replace, Reduce, Refine).

Question 11
Which member of the research team is responsible for planning and coordinating all phases of
the research work?
A) Laboratory Animal Technician
B) Laboratory Animal Veterinarian
C) Principle Investigator (PI)
D) Facility Manager
E) Institutional Official (IO)
