- The LATG exam has exactly 180 multiple-choice questions in three hours, split across two equally weighted domains.
- Domain 1 (Husbandry, Health, Welfare) and Domain 2 (Facility Administration and Management) are each worth 50%.
- Eligibility ranges from five years of work with a GED to six months after earning LAT.
- One qualifying work year equals 1,950 hours - track your hours, not just your job title.
LATG Certification Snapshot
If you need the entire credential distilled into a glance, this is it. The LATG (Laboratory Animal Technologist) certification is administered by the American Association for Laboratory Animal Science Certification and Registry Board, and the exam itself is delivered through Prometric - either at a physical test center or via remotely proctored internet testing. That flexibility matters when you're scheduling around shift work in a vivarium or research facility.
The current publicly available application, revised March 2024, lists the fee at $275 for AALAS members and $350 for nonmembers. That's a meaningful gap, and it's one of the first things worth checking before you register - see the full breakdown in LATG Certification Cost 2026: Complete Pricing Breakdown.
The Two Domains, Weighted Equally
Unlike some certifications that spread content across many unevenly weighted categories, the LATG exam blueprint is refreshingly simple: two domains, each worth exactly 50%. That means you cannot afford to treat either one as secondary.
Domain 1: Animal Husbandry, Health, and Welfare (50%)
This domain covers the day-to-day and clinical realities of animal care at the technologist level - beyond basic technician tasks and into oversight, troubleshooting, and welfare judgment calls.
- Species-specific husbandry standards and environmental enrichment
- Recognizing and responding to clinical signs of illness or distress
- Biosecurity, sanitation, and disease prevention protocols
- Welfare assessment frameworks and humane endpoints
Domain 2: Facility Administration and Management (50%)
This domain shifts from the animal to the operation - how a lab animal program is run, staffed, documented, and kept compliant.
- Regulatory frameworks and institutional oversight (IACUC-related processes)
- Personnel management, training, and occupational health programs
- Facility design, equipment maintenance, and emergency planning
- Recordkeeping, SOP development, and quality assurance
Because the two domains are equally weighted, a common mistake is over-studying husbandry content out of comfort (it feels more hands-on and familiar) while under-preparing for administrative material that feels dry but carries identical exam weight. For a deeper walkthrough of every subtopic inside each domain, see LATG Exam Domains 2026: Complete Guide to All 2 Content Areas.
Question Format and Exam-Day Mechanics
Every question on the LATG exam follows the same structure: one correct answer surrounded by three distractors. There's no partial credit, no "select all that apply," and no essay component. That consistency is actually an advantage - once you understand how AALAS writes distractors, you can train yourself to spot them.
Distractors on technologist-level exams tend to fall into a few patterns:
- An answer that would be correct for a technician-level (ALAT/LAT) scope but is too basic for a supervisory LATG-level question
- A choice that's factually true in general animal care but wrong for the specific species or regulatory context in the question stem
- An answer that describes the "textbook" version of a procedure rather than the version consistent with facility administration realities in Domain 2
With 180 questions in three hours, you have roughly one minute per question - enough time to read carefully but not enough to dwell. Pacing practice matters as much as content review. For a realistic sense of how demanding this really is compared to other AALAS credentials, read How Hard Is the LATG Exam? Complete Difficulty Guide 2026.
Key Takeaway
Practice full-length 180-question timed sets, not just topic quizzes. Pacing under real time pressure is a skill separate from knowing the content, and it's best rehearsed on our full-length LATG practice tests.
Eligibility Cheat Sheet
Before you even think about domain content, confirm you're eligible - this trips up more candidates than the exam itself. Eligibility is based on qualifying laboratory-animal work experience, combined with education level or prior AALAS certification.
| Education / Prior Credential | Required Qualifying Experience |
|---|---|
| High school diploma or GED | 5 years |
| Associate degree | 4 years |
| Bachelor's degree | 3 years |
| Current LAT certification | 6 months after earning LAT |
One qualifying work year is defined as 1,950 hours - not a calendar year, and not a full-time 2,080-hour year. Keep documentation of actual hours worked in qualifying roles, since AALAS may request verification. A full explanation of how these pathways work, including what counts as "qualifying" experience, is in LATG Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Fees, Registration, and Renewal
The application currently in circulation (revised March 2024) sets member pricing at $275 and nonmember pricing at $350. If you're not already an AALAS member, it's worth running the math on whether membership dues plus the member fee beat the flat nonmember fee - often they do, especially if you plan to pursue continuing education afterward.
Testing itself happens through Prometric, giving you the choice between an in-person test center or remote online proctoring. Choose based on your home environment: remote testing requires a quiet, private space free of interruptions for the full three-hour block.
Don't confuse the two. Plenty of certified LATGs never pursue the Registered status, and that's a legitimate choice depending on career goals.

Domain 1 Must-Know Facts
Here are the specific facts and concepts candidates most often need to lock down for Domain 1:
- Species-specific baseline parameters: normal physiological ranges, housing density requirements, and environmental enrichment expectations differ by species - questions frequently test whether you know which standard applies to which animal.
- Clinical observation vocabulary: the precise terminology used to describe abnormal findings (e.g., piloerection, hunched posture, porphyrin staining) shows up in scenario-based questions describing an animal's condition.
- Zoonotic disease awareness: transmission routes and prevention protocols for common zoonoses relevant to the species housed in a typical facility.
- Humane endpoints and euthanasia methods: knowing which methods are appropriate per species and per AVMA-aligned guidelines, and recognizing when a humane endpoint has been reached.
- Enrichment and social housing: the welfare rationale behind group housing, environmental complexity, and exceptions for single housing.
This domain rewards technologists who have supervised or trained others in husbandry procedures, not just performed them - the exam expects a "why" behind each protocol, not just the "what."
Domain 2 Must-Know Facts
Facility Administration and Management is where many technicians moving up from LAT feel less confident. These are the areas to prioritize:
- Regulatory and oversight structures: understanding the role of institutional oversight committees in reviewing and approving animal use, and how facility staff interact with that process.
- Occupational health and safety programs: what an effective occupational health program for animal care staff includes, and how exposure risks are managed and documented.
- Training and competency documentation: how facilities are expected to train, evaluate, and document competency for personnel at different job levels.
- Facility design and equipment: ventilation, caging systems, sanitation equipment validation, and preventive maintenance scheduling.
- Emergency and contingency planning: disaster preparedness, power-failure protocols, and business continuity for animal colonies.
- Recordkeeping standards: what must be documented, retained, and made available for inspection or audit.
Key Takeaway
Treat Domain 2 as equally testable as Domain 1 - it carries the same 50% weight, and questions here are often scenario-based rather than pure recall, testing judgment about "what should this facility do."

Who Hires LATGs
LATG certification signals a technologist-level skill set - supervisory competence in both animal care and facility operations. That combination is what makes the credential attractive to employers running larger or more complex vivaria:
- Academic research institutions and university animal facilities
- Pharmaceutical and biotech companies with in-house animal research programs
- Contract research organizations (CROs)
- Government and federal research laboratories
- Zoos, aquariums, and specialized breeding facilities
Because the certification is awarded for life, it remains a durable line on a resume even if you move between employer types.

Frequently Asked Questions
The exam contains 180 multiple-choice questions, each with one correct answer and three distractors, to be completed within three hours.
No. Animal Husbandry, Health, and Welfare and Facility Administration and Management are each weighted at exactly 50%, so both require equal study attention.
No. LATG certification is awarded for life. The separate, voluntary Registered LATG status does require renewal every two years with 24 continuing-education units, but that's optional and distinct from base certification.
Holding a current LAT certification is the fastest route, requiring only six months of additional qualifying work afterward. Without LAT, the requirement ranges from three years (bachelor's degree) to five years (high school diploma or GED) of qualifying experience, where one year equals 1,950 hours.
Based on the application revised March 2024, the fee is $275 for AALAS members and $350 for nonmembers, paid to register through Prometric-administered testing.
