What Is LATG Certification?

What Is LATG Certification?

LATG stands for Laboratory Animal Technologist, and it is the most advanced of the three certification levels administered by the American Association for Laboratory Animal Science (AALAS) Certification and Registry Board. If you've already searched terms like what is LATG, LATG meaning, or what does LATG stand for, this article pulls those threads together with the concrete mechanics of the credential itself: who runs it, how the exam is built, what it costs, and what it takes to qualify.

Unlike a course completion certificate, LATG is a professional credential earned by passing a proctored exam that tests both hands-on animal care knowledge and facility-level management competence. It sits above the entry-level Assistant Laboratory Animal Technician (ALAT) and the mid-level Laboratory Animal Technician (LAT) in the AALAS technician career ladder, and it's typically pursued by people who already supervise staff, manage colony health programs, or oversee compliance within a vivarium.

Who Administers the Exam and How It's Delivered

The AALAS Certification and Registry Board owns and administers the LATG credential. Testing itself is delivered through Prometric, meaning candidates can sit for the exam either at a physical Prometric test center or via remotely proctored internet testing from a private location that meets the proctor's requirements. This dual-delivery option gives candidates in rural areas or those with scheduling constraints more flexibility than a single fixed test-center model.

The exam is offered in English. Scheduling logistics, blackout periods, and appointment windows are covered in more depth in our LATG exam dates guide, which is worth reviewing before you lock in a registration date, since Prometric appointment availability can vary by region and season.

Eligibility: Who Can Sit for the LATG Exam

AALAS uses a sliding scale that combines education level with qualifying laboratory-animal work experience. The more formal education you have, the less on-the-job experience is required. Eligibility paths are:

• High school diploma or GED: five years of qualifying laboratory-animal work experience
• Associate degree: four years of qualifying experience
• Bachelor's degree: three years of qualifying experience
• Already hold LAT certification: six months of additional qualifying experience

One "qualifying work year" is defined by AALAS as 1,950 hours, not a simple calendar year, so part-time or seasonal work needs to be converted carefully when you tally your hours. For a full breakdown of how these hours are calculated, what counts as qualifying work, and how to document your experience on the application, see our dedicated LATG requirements guide.

Exam Format and Question Style

The LATG exam consists of 180 multiple-choice questions, administered in a three-hour window. Every question has exactly one correct answer and three distractors - there is no "select all that apply," no fill-in-the-blank, and no written-response component. This four-option, single-answer format is consistent across all AALAS technician-level certifications, but the LATG version draws on more advanced, supervisory-level scenarios than the ALAT or LAT exams.

Because every question is weighted the same and there's no partial credit, pacing matters. At three hours for 180 questions, you have an average of one minute per question, though in practice most candidates move faster through recall-based questions and slower through applied scenario questions involving regulatory interpretation or husbandry troubleshooting. For a detailed discussion of what "hard" actually means for this specific exam - question complexity, time pressure, and content depth - read our guide on how hard the LATG exam really is.

The publicly reported first-time pass rate was 64% for 2014, based on the AALAS handbook. That figure gives a sense of the exam's rigor, though it's a single historical data point rather than a current annual statistic. We break down what this number does and doesn't tell you in our LATG pass rate analysis.

The Two Content Domains

LATG content is organized into exactly two domains, and - unlike some other certification exams that spread weight unevenly - AALAS weights them equally at 50% each. That even split has a direct practical implication: neither domain can be treated as a minor topic, and skipping facility management content because it feels less "hands-on" than animal care is a common and costly mistake.

Because these two domains carry identical weight, your study plan should allocate roughly equal time to each rather than defaulting to whichever feels more familiar from daily work. For a topic-by-topic breakdown of subtopics within each domain, our LATG exam domains guide goes deeper than what's practical to cover here.

Fees, Registration, and Renewal

Based on the AALAS application revised in March 2024, the LATG exam fee is $275 for AALAS members and $350 for nonmembers. This fee difference is often larger than the cost of an annual AALAS membership itself, so many candidates join before applying to test. Fees are subject to change, and AALAS publishes the current application on its own site, but these are the most recently confirmed figures.

Once earned, LATG certification itself never expires - it's awarded for life. However, AALAS also offers a voluntary "Registered LATG" designation, which requires renewal every two years and 24 continuing-education units within that renewal cycle. This distinction trips up a lot of certified technologists: the base LATG credential is permanent, but the Registered status is an optional, renewable add-on that some employers or state programs specifically request. For the full cost picture, including membership tiers, retake fees, and how the fee structure compares across AALAS certification levels, see our LATG certification cost breakdown.

Who Earns LATG and Why It Matters

LATG certification is generally pursued by technicians who have moved into, or are aiming for, roles with supervisory or program-level responsibility - think facility supervisors, animal care program coordinators, or technologists preparing to step into management within a vivarium, contract research organization, pharmaceutical company, or academic animal facility. Because half the exam covers facility administration and management, employers often view LATG as a signal that a candidate can handle regulatory compliance conversations, train junior staff, and manage operational details, not just execute hands-on husbandry tasks.

Mapping Your Prep to the Two Domains

Because LATG has only two domains and they're weighted identically, a simple and effective way to structure preparation is to alternate focus weeks between them, then finish with mixed practice that mirrors the exam's actual mixed-domain question order. This isn't a generic study calendar - it's built around the specific 50/50 split unique to this exam.

For a more detailed week-by-week plan, including how to sequence review sessions around your work schedule, see our full LATG study guide for 2026. And if you want a fast-reference summary of must-know facts to review the week of your exam, our LATG cheat sheet condenses key figures - like the eligibility hour requirements and exam format - into a single page.

Practicing with realistic, timed multiple-choice questions on our LATG practice test platform is one of the most direct ways to get comfortable with the four-option, single-answer format before exam day. Working through full-length simulations on the practice site also helps you calibrate pacing against the three-hour, 180-question structure rather than guessing at timing on test day.
