Laboratory Animal Technologist (LATG) Certification Exam

The Laboratory Animal Technologist (LATG) Certification Exam is an advanced certification examination for professionals working in laboratory animal science. It is administered through the American Association for Laboratory Animal Science (AALAS) and covers animal husbandry, health and welfare, facility administration, management, and related professional knowledge.

What Is the Laboratory Animal Technologist (LATG) Certification?

The LATG is the highest level in the AALAS technician certification program, following the ALAT and LAT levels. It is intended for professionals with advanced knowledge and experience in laboratory animal care and facility operations.

The examination is designed around knowledge and skills needed in real laboratory animal facilities. AALAS emphasizes that classroom preparation alone is not sufficient and that relevant work experience is an important part of preparing for the certification examination.

Because the LATG covers a broad range of responsibilities, preparation needs to go beyond basic animal care. Candidates should be comfortable with both hands-on laboratory animal practices and the administrative side of operating an animal care program.

What Topics Are Covered on the LATG Exam?

The current AALAS LATG Exam Content Outline divides the examination into two major domains:

• Animal Husbandry, Health, and Welfare — 50%
• Facility Administration and Management — 50%

The first area covers many aspects of animal care, while the second focuses more heavily on facility operations and management.

Topics within animal husbandry, health, and welfare include:

• Animal identification
• Species-specific biology and behavior
• Breeding and genetics
• Nutrition
• Housing and husbandry
• Sanitation and disease prevention
• Clinical and research procedures
• Dosage and dilution calculations
• Animal welfare
• Environmental enrichment
• Handling and transportation

Facility administration and management involves a different set of responsibilities, including the organization and management of laboratory animal programs.

How Does the LATG Exam Differ From LAT?

The LATG represents a higher certification level than the LAT.

The AALAS certification structure consists of three levels:

1. Assistant Laboratory Animal Technician (ALAT)
2. Laboratory Animal Technician (LAT)
3. Laboratory Animal Technologist (LATG)

The LATG examination builds on knowledge covered at the earlier levels. AALAS specifically states that LATG candidates should study materials associated with the ALAT, LAT, and LATG levels.

This is important when creating a preparation plan. Focusing exclusively on the LATG Training Manual may leave gaps because the certification examination draws from the broader set of AALAS training and reference materials.

What Is the LATG Exam Format?

The AALAS Technician Certification Handbook lists the LATG examination as a 180-question multiple-choice exam with a three-hour time limit. Each question has one correct answer and three incorrect answer choices.

The examination is offered through computer-based testing, with Prometric serving as the testing provider. Prometric also provides information about AALAS certification examinations and reference materials.

With 180 questions in three hours, candidates need to manage their time carefully. Spending too long on a difficult question can reduce the time available for questions that may be easier.

What Is the Best Way to Prepare for LATG?

A strong LATG preparation plan should combine official study resources with practical experience.

Begin with the current LATG Exam Content Outline. It provides a useful map of the areas that deserve attention. Once you know the major domains, divide your preparation into smaller subjects.

For example, animal husbandry preparation can be separated into nutrition, housing, sanitation, disease prevention, clinical procedures, calculations, and welfare.

Facility management can then be studied separately so that administrative subjects do not get mixed together with animal-care topics.

Practice questions can also help. Rather than memorizing answers, review the reasoning behind each question and connect it to the relevant training material.

Why Is Practical Experience Important?

Laboratory animal science involves practical situations that are difficult to understand through memorization alone.

The AALAS LATG content outline specifically notes that work experience in an animal facility is necessary for exam preparation and recommends experience across different areas of facility operations.

For example, candidates may encounter topics involving animal handling, environmental monitoring, sanitation, breeding, health observations, euthanasia, or facility management. Practical exposure can make these subjects much easier to understand.

Cross-training in different areas of a facility can therefore be valuable preparation.

How Can You Improve LATG Exam Preparation?

One useful approach is to create a topic-based study schedule.

Start with areas that carry substantial weight in the content outline. Clinical, health, and research procedures, husbandry practices, sanitation, disease prevention, and animal welfare are among the detailed areas listed under the animal husbandry domain.

Do not ignore calculations. Temperature conversions, weights and measures, dosage calculations, and dilution calculations are specifically included in the content outline.

It is also worth practicing with a timer. The objective is not simply to answer questions correctly but to become comfortable making decisions within the available examination time.

What Study Materials Should LATG Candidates Use?

AALAS recommends studying the training manuals and reference lists associated with the certification levels.

The LATG examination draws from:

• LATG Training Manual
• LATG reference materials
• LAT Training Manual
• LAT reference materials
• ALAT Training Manual
• ALAT reference materials

AALAS notes that the LATG workbook by itself is not sufficient preparation because the actual certification examination covers the broader collection of materials.

Candidates should therefore use the current AALAS reference list rather than relying exclusively on third-party question banks.

Frequently Asked Questions

What does LATG stand for?

LATG stands for Laboratory Animal Technologist.

Who administers the LATG certification?

The certification program is administered by the American Association for Laboratory Animal Science (AALAS) through its certification program.

How many questions are on the LATG exam?

The current AALAS Technician Certification Handbook lists 180 multiple-choice questions for the LATG examination.

How long is the LATG exam?

The listed examination time is three hours.

What are the major LATG exam domains?

The current content outline divides the exam equally between Animal Husbandry, Health, and Welfare and Facility Administration and Management.

Is practical experience important for LATG preparation?

Yes. AALAS states that work experience in an animal facility is necessary for exam preparation and is part of the certification eligibility requirements.

Should LATG candidates study ALAT and LAT materials?

Yes. AALAS states that the LATG examination covers material from the ALAT, LAT, and LATG training materials and reference lists.

Does the LATG exam include calculations?

Yes. The LATG content outline includes temperature conversion, weights and measures, dosage calculations, and dilution calculations.

Final Thoughts

The Laboratory Animal Technologist (LATG) Certification Exam requires broad knowledge of laboratory animal care as well as facility administration and management. Because the exam covers material from multiple AALAS certification levels, preparation should be comprehensive rather than limited to one manual or a collection of practice questions.

A practical combination of hands-on experience, current AALAS reference materials, content-outline review, and timed practice can help candidates build a stronger understanding of the subjects covered by the LATG examination.
