LATG Certification

What Is LATG Certification?

LATG stands for Laboratory Animal Technologist, the most advanced of the three technician-level credentials offered by the American Association for Laboratory Animal Science (AALAS), sitting above the ALAT and LAT designations. If you're still sorting out how these acronyms relate to each other, the companion pieces What Is LATG?, LATG Meaning, and What Does LATG Stand For? cover the terminology in depth. This article focuses specifically on the certification mechanics: who administers it, what it costs, how the exam is structured, and what a candidate actually needs to know to pass.

Unlike entry-level credentials, LATG is designed for professionals who already carry substantial hands-on responsibility in animal research facilities - often supervisory, quality-control, or training roles. For a broader look at what the credential signals to employers, see What Is A LATG? and What Is LATG Certification?.

Who Administers the Exam and How

The AALAS Certification and Registry Board (CRB) owns and administers the LATG credential. Delivery, however, runs through Prometric, meaning candidates sit for the exam either at a physical Prometric test center or via remotely proctored internet testing from a private location that meets Prometric's technical and environmental requirements. This dual-delivery model gives candidates in rural or facility-restricted regions a realistic path to certification without traveling to a testing site.

Eligibility Requirements

LATG eligibility is built entirely around documented, qualifying laboratory-animal work experience, with the required duration shrinking as formal education increases:

• Five years of qualifying experience with a high school diploma or GED
• Four years of qualifying experience with an associate degree
• Three years of qualifying experience with a bachelor's degree
• Six months of qualifying experience after already holding the LAT credential

AALAS defines one qualifying work year as 1,950 hours, so part-time or seasonal roles must be totaled carefully rather than assumed to count on a calendar-year basis. This distinction trips up more candidates than any content-area question on the exam itself. A full breakdown of documentation requirements, acceptable job duties, and how to calculate hours lives in LATG Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Exam Format and Question Style

The LATG exam consists of 180 multiple-choice questions administered over three hours, in English. Each question presents one correct answer alongside three distractors - a straightforward four-option format, but one that rewards precision because distractors are often built from common misapplications of correct procedure rather than obviously wrong answers.

Given the volume of questions relative to time, most candidates average roughly one minute per question, which leaves little room for second-guessing on items outside your daily work experience. Understanding this pacing constraint matters more at the LATG level than at ALAT or LAT, since technologist-level questions frequently describe multi-step scenarios (e.g., a facility deviation, a health surveillance anomaly, an SOP conflict) rather than single-fact recall.

The Two Content Domains

LATG content is organized into exactly two domains, each weighted equally at 50% of the exam. This 50/50 split is a defining structural feature of LATG - unlike some other certifications that spread weight unevenly across three or four areas, every LATG candidate needs comparable depth in both domains to pass reliably.

Because both domains carry identical weight, allocating study time unevenly is one of the most common - and most avoidable - mistakes candidates make. A candidate strong in husbandry but weak in administrative topics can miss the passing threshold despite excelling on half the exam. For a topic-by-topic breakdown with study priorities inside each domain, see LATG Exam Domains 2026: Complete Guide to All 2 Content Areas.

Cost and Fee Structure

According to the most recent publicly available AALAS application (revised March 2024), the LATG exam fee is:

The $75 difference is often enough to offset the cost of an AALAS membership itself, which is worth calculating before you submit payment. A full breakdown of what's included in this fee, retest costs, and how it compares to ALAT and LAT pricing is available in LATG Certification Cost 2026: Complete Pricing Breakdown.

Pass Rate Context

The publicly available AALAS handbook reports a 64% first-time pass rate for LATG in 2014 - the most recent figure published in that source. That number reflects the exam's technologist-level difficulty: candidates are expected to bring supervisory and administrative knowledge in addition to hands-on husbandry competence, and the 50/50 domain split means gaps in either area carry real consequences. Rather than treating that figure as discouraging, use it as a planning signal that LATG deserves dedicated, domain-balanced preparation rather than a quick review the week before your test date.

Preparing for the LATG Exam

The current public LATG training materials and handbook are the 2016 edition, which remains the baseline reference for content scope even though regulatory guidance documents (such as the Guide for the Care and Use of Laboratory Animals) continue to be referenced within that framework. Building a study plan around this handbook, supplemented by realistic practice questions, is the most direct path to exam readiness.

A simple way to structure preparation is to treat the two domains as two separate study tracks that converge in the final weeks:

This isn't a generic spaced-repetition template - it's built around the fact that LATG's two domains are equally weighted and cover genuinely different skill sets (clinical/technical vs. administrative/regulatory), so studying them separately before integrating avoids the common trap of over-focusing on animal care content at the expense of facility management topics.

After You Certify: Renewal and RLATG

LATG certification itself is awarded for life - once you pass, you do not need to retest or renew the base credential. However, AALAS also offers a voluntary Registered LATG (RLATG) status, which is renewed every two years and requires 24 continuing-education units within that period. RLATG signals active, ongoing professional development beyond the one-time exam, which some employers and grant-funded institutions specifically look for in supervisory hires.

Who Hires LATG-Certified Professionals

LATG-credentialed staff typically work in academic research universities, pharmaceutical and biotech companies, contract research organizations (CROs), government research facilities, and veterinary or biomedical research divisions. Because the credential's Facility Administration and Management domain covers supervisory and compliance knowledge, LATG holders are frequently considered for lead technician, facility supervisor, training coordinator, and quality-assurance roles rather than purely task-based positions. If you're evaluating career trajectory and compensation potential tied to the credential, LATG Salary Guide 2026: Complete Earnings Analysis and Is the LATG Certification Worth It?
