What Does ALS Mean?

What ALS Actually Stands For

ALS stands for Andrology Laboratory Scientist, a professional certification for laboratory personnel who perform semen analysis, sperm function testing, and other reproductive laboratory procedures used in fertility diagnostics and treatment. If you searched "what does ALS mean" hoping for a quick definition, that's it - but the credential itself is more nuanced than a three-letter acronym suggests, and it's worth understanding exactly what it verifies before you commit time and money to pursuing it.

Unlike broader lab science credentials that cover multiple specialties, ALS is narrowly focused on andrology - the clinical study of male reproductive health and fertility. That specificity shows up directly in how the certification exam is built, which is why generic laboratory-science study advice only gets a candidate partway there. For a deeper dive into the term itself, see our companion pieces on What Is ALS?, ALS Meaning, and What Does ALS Stand For?

Who Certifies ALS and Why It Matters

The AAB Board of Registry (ABOR) administers the ALS credential. ABOR is the certifying body responsible for setting eligibility standards, writing and scoring the exams, and maintaining the registry of certified andrology laboratory scientists. Because ABOR - not a hospital, not an employer, not a state agency - controls the standard, every requirement discussed in this article (exam format, fees, renewal) traces back to ABOR policy specifically for this credential.

This matters because several other credentials in healthcare and beyond also use the initials "ALS." If you find information online about exam fees, pass rates, or domain weighting that doesn't match what's described here, it likely belongs to a different certification entirely. Always confirm you're reading about the Andrology Laboratory Scientist certification specifically before applying facts to your prep plan.

The Two-Exam Structure

ALS certification requires passing two separate written multiple-choice examinations, not one combined test. Understanding this structure early changes how you plan your study timeline, because each exam is scored independently and each has its own pass threshold.

Both exams are proctored, and calculators and outside notes are prohibited during testing. Candidates commonly take both exams on the same day, which affects scheduling but not the difficulty of either individual test - each is graded on its own merits against the 60% threshold. For a full content breakdown of what each domain actually tests, see the ALS Exam Domains Guide, and for an honest assessment of the challenge level, check How Hard Is the ALS Exam?

Eligibility Routes to Sit for ALS

ABOR offers four education routes to eligibility, giving candidates from different academic backgrounds a path into the profession. Alongside meeting one of these education routes, candidates must also complete either an approved clinical laboratory training program or at least three months of full-time high-complexity andrology laboratory training or experience within the preceding 10 years.

This dual requirement - education plus hands-on training - reflects the applied nature of andrology work. Reading about sperm morphology assessment or motility grading is not the same as having performed it under supervision, and ABOR's eligibility structure is built to confirm both. For the complete breakdown of each education pathway and how the training requirement is verified, read our detailed ALS Requirements guide.

Fees and Registration Mechanics

ALS registration involves several separate line items rather than one flat exam fee, and understanding the breakdown helps candidates budget accurately and avoid surprises on test day.

Note that if you use a college or university proctor instead of an AAB proctor, that proctor's fee is paid separately and is not included in the $320 same-day figure above. Candidates who plan to test at an academic institution rather than through AAB directly should confirm that separate cost ahead of time. For a complete line-by-line pricing analysis, including how the fee structure compares across scenarios, see ALS Certification Cost 2026.

Provisional Status: ALS-P(AAB)

Not every candidate completes the education and training requirements at the same pace. ABOR accounts for this with a provisional designation: candidates who meet the education requirement before completing the clinical training or experience requirement can earn ALS-P(AAB) provisional status.

This provisional pathway lets qualified candidates begin working toward full certification while they accumulate the remaining hands-on hours, rather than being blocked entirely until every box is checked. It's a meaningful detail for career planning, especially for recent graduates entering andrology laboratories who haven't yet hit the three-month experience threshold.

Keeping ALS Active

Once earned, ALS certification renews annually for $115. Notably, ABOR does not impose a continuing-education requirement to maintain the credential - renewal is fee-based rather than tied to completing coursework or documented CE hours each year.

However, lapses are not indefinite. If a certification holder goes three years without renewing, the certification file closes. At that point, regaining certification likely means re-establishing eligibility and retesting rather than simply paying back fees, so treat the annual renewal as a firm deadline rather than a flexible suggestion.

Who Hires ALS-Certified Professionals

ALS-certified professionals typically work in clinical andrology laboratories that support fertility clinics, reproductive endocrinology practices, and hospital-based labs performing semen analysis and related reproductive testing. Employers value the credential because it verifies both the academic foundation covered in the Basic Knowledge exam and the specialized, hands-on competency tested in the Andrology exam.

For candidates weighing whether pursuing ALS makes sense given their career goals, it's worth reading both ALS Jobs for a sense of where the credential is used in practice, and Is the ALS Certification Worth It? for a broader return-on-investment discussion. If compensation is a driving factor in your decision, the ALS Salary Guide lays out what's currently known about earnings in this niche.

Preparing for Both Exams

Because ALS certification hinges on two independently scored exams rather than one, a study plan built around a single generic timeline tends to underserve one domain or the other. A more effective approach treats Basic Knowledge and Andrology as two distinct study tracks that converge only at test time.

For a structured, week-by-week plan built specifically around these two domains, see the ALS Study Guide 2026. It's also worth reviewing exactly what "passing" requires before you begin - our ALS Passing Score guide breaks down the 60% threshold for each exam in more detail, and the ALS Cheat Sheet condenses must-know facts into a single reference page for final review.

If you want to gauge readiness under realistic conditions before exam day, practicing with timed, exam-style questions on our practice test platform can help you get comfortable with the 90-minute pacing required for both the Basic Knowledge and Andrology exams. Running through several full-length simulations on the main practice site is one of the more direct ways to confirm you're hitting the 60% mark consistently before you pay the registration fee.
