Last updated: September 7, 2026 · Fact-checked against official Biotility sources, including the current BACE FAQ, the BACE Exam Site Support Hub, and the BACE individual registration page
This guide covers what the BACE is, how it's structured, and how to study for it — content that holds steady year to year. For the AY 2026–2027 calendar specifically (registration windows, ordering deadlines, what's different this cycle), see the companion BACE Exam Dates & Deadlines: AY 2026–2027 page, which we'll keep current as Biotility publishes new dates.
If you've been searching for a clear breakdown of the BACE exam, this is it. It covers everything you need to understand what the exam is, how it's structured, how to register, and how to walk in prepared to pass.
Whether you're a high school student, a community college candidate, or a career-changer who wants a credentialed foot in the door of biotech, this guide covers it all.
What Is the BACE Exam?
The BACE exam — formally the Biotechnology Aptitude and Competency Exam — is an industry-recognized credential that proves you have the foundational knowledge and lab skills to work as an entry-level biotechnician.
It's developed and administered by Biotility at the University of Florida, specifically through UF's Center of Excellence for Regenerative Health Biotechnology (UF CERHB) — a center that marked its 20th anniversary in 2026. The BACE credential itself dates to 2012, when it was added to Florida's list of industry-recognized credentials, and it's grown substantially since then. As of mid-2026, it's formally adopted as a state-recognized credential in 20 states and Washington D.C., and it's actively used — without formal state adoption — in 17 more states, putting it in active use across 37 states and D.C. total. It's also backed by national organizations including InnovATEBIO, NIIMBL, and BioFlorida.
What makes the BACE different from a school exam is how it was built. The content comes from a DACUM (Developing a Curriculum) analysis — a process where working biotech professionals define the exact skills someone needs to perform on day one of a technician role. Biotility's National Advisory Board reviews and updates the exam annually, and the whole thing is developed to ISO/IEC 17024 standards — the same international framework used for professional certification bodies worldwide.
The bottom line: employers trust it because it wasn't designed by educators — it was designed by the people who do the hiring.
What Does BACE Stand For?
BACE stands for Biotechnology Aptitude and Competency Exam.
You'll sometimes also see it called the Biotechnician Assistant Credentialing Exam — that was the older name before Biotility updated the branding to reflect the credential's broader use beyond just "assistant" roles. Same exam, same acronym, same credential.
Who Should Take the BACE?
The short answer: anyone preparing to enter the biotechnology workforce at the technician level. That covers a wider range than most people expect.
High school students in CTE, biomedical science, or biotechnology programs — many schools in Florida, Texas, Virginia, Ohio, and Kansas embed the BACE directly into their programs as an exit credential.
Community college students working toward an A.S. in biotech or a related field. In Florida, passing the BACE earns you three postsecondary credit hours in any Associate of Science Biotechnology program.
Career changers with lab backgrounds from adjacent fields — clinical labs, food science, quality control — who want a recognized credential that translates into biotech.
Undergraduate students looking for something tangible to show employers alongside an incomplete four-year degree.
No specific degree is required to sit for the exam. That said, Biotility recommends coming in with at least a solid intro biology lab background — if you've worked with a micropipette, run a gel, and used a spectrophotometer, you're at the right starting point.
BACE Exam Format
Here's the full picture in one place:
| Detail | Value |
|---|---|
| Total questions | 116 |
| Total points | 175 |
| Time allowed | 4 hours |
| Passing score | 80% overall |
| Portions | 2 (Knowledge + Practical) |
| Delivery format | Computer-based only (as of AY 2025–2026) |
| Maximum attempts | 3 |
| Waiting period between attempts | 20 days minimum |
| Credential validity | 5 years from your pass date |
| Remote proctoring | ProctorU |
| Exam platform | UF e-Learning |
Two Portions, One Session
The BACE runs in a single continuous session. It has two portions — Knowledge and Practical — but you complete them together, not on separate days.
The Knowledge Portion tests your theoretical understanding: concepts, safety regulations, biochemistry, and quality systems. The Practical Portion tests whether you can apply that knowledge to real lab scenarios — equipment use, solution prep, data interpretation, experimental design. Both are now delivered as computer-based, scenario-driven multiple-choice and matching questions.
How Your 3 Attempts Are Tracked
The "3 attempts" rule works slightly differently depending on how you register. If you test through an Exam Site, your attempts follow that site's academic-year testing calendar (more on this below). If you register individually through the Remote Testing Option, Biotility tracks your three attempts within a rolling 12-month period starting from your first test date — not a fixed academic year. Either way, the mandatory 20-day wait between attempts still applies.
Your final score is the average of your highest Knowledge score and your highest Practical score across your attempts.
As of the 2025–2026 academic year, the BACE is exclusively computer-based. The paper-based option has been permanently retired. Biotility confirmed this transition is supported by third-party outcome studies showing equivalent pass rates.
Where You Take It
At an Exam Site — the most common route if you're enrolled at a participating high school or college. Your site administrator handles registration, and a certified proctor supervises in a computer lab.
Remote Testing Option (RTO) — if you're not affiliated with a registered site, you can register individually and take the exam from home with live ProctorU supervision. This opened up access significantly, especially for working adults and people in areas without a nearby exam site.
The 8 BACE Exam Categories
The 116 questions are split across eight categories — four in each portion. Here's the breakdown from the official AY 2025–2026 Exam Specifications:
Knowledge Portion
| Category | Questions | Points | % of Total |
|---|---|---|---|
| Technical Skills & Applications | 22 | 33.25 | 19% |
| Safety & Workplace Culture | 15 | 21 | 12% |
| Biochemistry & Molecular Biology | 15 | 17.5 | 10% |
| Regulation & Quality | 12 | 15.75 | 9% |
Practical Portion
| Category | Questions | Points | % of Total |
|---|---|---|---|
| Biotechnology Skills | 19 | 40.25 | 23% |
| Applied Mathematics | 13 | 21 | 12% |
| Standard Equipment | 10 | 14 | 8% |
| Experimental Design & Data Analysis | 10 | 12.25 | 7% |
Total: 116 questions · 175 points
Here's what each category actually covers in practice:
Technical Skills & Applications (19%)
This is your daily-driver biotechnician toolkit — aseptic technique, cell culture, PCR, gel electrophoresis, protein quantification, microscopy, and basic bioprocessing. Questions don't just ask you to define these things; they put you in realistic scenarios and ask what you'd actually do.
Safety & Workplace Culture (12%)
OSHA regulations, SDS (Safety Data Sheets), PPE selection, biosafety levels (BSL-1 through BSL-4), chemical and biohazard waste handling, and professional conduct in a regulated lab environment. Bioethics also falls here.
Biochemistry & Molecular Biology (10%)
The science underpinning everything else — cell structure, DNA replication, transcription and translation, enzyme kinetics, macromolecule function, and the basics of recombinant DNA technology. If you haven't reviewed this material recently, budget some time for it.
Regulation & Quality (9%)
cGMP (Current Good Manufacturing Practices), SOPs, data integrity, the distinction between Quality Assurance and Quality Control, and the roles of regulatory agencies like the FDA, EPA, and USDA. Candidates from purely academic backgrounds often underestimate this section.
Biotechnology Skills (23% — the biggest category)
The heaviest single category on the whole exam. This is hands-on procedural competency: accurate pipetting, buffer and reagent preparation, aseptic transfers, proper use of biological safety cabinets and autoclaves, and lab documentation (SOPs, batch records, lab notebooks). Think of it as: could you run this protocol correctly without someone watching over your shoulder?
Applied Mathematics (12%)
This is where many first-time candidates lose points, so take it seriously. The math itself isn't advanced — it's arithmetic and unit conversions — but it has to be done accurately under time pressure.
Focus on: serial dilutions, molarity calculations (C₁V₁ = C₂V₂), percent concentration (w/v, v/v, w/w), and scientific notation with significant figures. Biotility explicitly flags these in their official math skills module as the most common stumbling blocks.
Standard Equipment (8%)
Know how to correctly use — not just name — a micropipette, spectrophotometer, centrifuge, PCR thermal cycler, gel electrophoresis system, pH meter, and microscope. Understand Beer-Lambert Law, RPM vs. RCF, and why Taq polymerase is heat-stable. Equipment questions also bleed into the Biotechnology Skills section.
Experimental Design & Data Analysis (7%)
Controls (positive, negative), variables, replication, hypothesis formation, graphing data, and identifying sources of error. More "scientific thinking" than memorization.
BACE Exam Pass Rate and Difficulty
Biotility does not publish a single, official national pass rate. However, some individual school districts have historically reported local pass rates averaging around 63%.
(Note: If you see much lower pass rates floating around online, ensure you aren't looking at data for the BACB — the Behavior Analyst Certification Board.)
The 80% passing threshold is meaningfully higher than most comparable credentialing exams, which typically require 70–75%. That bar is intentional — the biotech industry demands precision, and the BACE is designed to reflect that.
The Applied Mathematics and Biotechnology Skills sections are consistently the two areas where candidates lose the most points. Math trips up people who haven't practiced applied calculations in a while. Biotechnology Skills catches candidates who understand the concepts but haven't actually performed the procedures.
The 4-hour time limit is generous if you're well prepared, but serial dilution problems can eat time quickly if you're uncertain. If you're going in underprepared on math, the clock will feel short.
The good news: you get up to 3 attempts (tracked by academic-year calendar at Exam Sites, or a rolling 12-month window if you register remotely), with a 20-day waiting period between each. That's not a reason to go in underprepared, but it does mean one rough attempt doesn't end your path to the credential. Twenty days is only the floor, too — Biotility itself recommends candidates take four to six weeks between attempts where possible, to leave real time for targeted review rather than just re-sitting the same gaps.
The candidates most likely to pass on the first attempt are those who combine practice test work with hands-on lab time. Reading about pipetting is not the same as having done it. If you have access to a lab — even briefly — use it.
How to Register for the BACE
Through an Exam Site (Most Common)
If you're at a high school or college that participates as a Biotility-registered Exam Site:
- Contact your instructor or site administrator — they handle registration on the institution's behalf.
- Your site places an order with Biotility. Note: Sites must re-register every academic year even if they've participated before.
- You get free access to the BACE Practice Exam Course on UF e-Learning.
- Your site schedules the exam under a live certified proctor.
Individual / Remote Testing Option
If you're not affiliated with a registered exam site:
- Visit biotility.research.ufl.edu and navigate to Individual Registration under the BACE Credential section.
- Register through UF's Continuing Education portal.
- Take the exam remotely, monitored in real time by ProctorU.
- Make sure your computer, webcam, microphone, and internet connection meet ProctorU's technical requirements before your exam date.
Before you register, read the Candidate Information Bulletin (CIB). It covers all policies on eligibility, accommodations, retakes, and remote testing requirements.
If you're a site administrator, build in lead time. Biotility asks for six weeks' notice on first-attempt orders and two weeks' on retakes. Need to change an order? Changes within 14 days of placing it are free; after that, a 175changefee∗∗applies,andrushingafirst−attemptorderinundersixweekscostsa∗∗425 expedite fee (subject to availability — Biotility can't honor requests inside two weeks of the exam date at all). None of this applies to individual Remote Testing Option candidates, who register and schedule directly with ProctorU.
Where things stand right now (as of September 7, 2026): The AY 2025–2026 cycle is fully closed out — first-attempt testing ended July 15, retake orders were due July 27, and all retake testing wrapped by August 10. Biotility has confirmed that AY 2026–2027 Exam Site Registration opens September 21, 2026 — that's also the date updated documentation (a fresh Candidate Information Bulletin and Exam Specifications) for the new cycle goes live. If you're reading this before September 21, the category weights and forms linked below still reflect the AY 2025–2026 versions, which Biotility reviews and updates annually — expect small refinements, not a different exam. First-attempt exam ordering for sites typically reopens in October, once site registration closes. None of this affects the Remote Testing Option — individual/ProctorU registration stays open on-demand year-round regardless of the academic-year calendar. For the full academic-year calendar and what's new, see our BACE Exam Dates & Deadlines: AY 2026–2027 page.
BACE Exam Cost
Biotility publishes exact fees for both testing routes, and each one covers your first two attempts.
At an Exam Site (school/college): $185 per candidate. Your school or program registers as an Exam Site and typically pays Biotility directly, so you may not see a separate bill — check with your program administrator to confirm how your institution handles it.
Individual / Remote Testing Option (ProctorU):
- First attempt: $200
- Second attempt (if needed): Free
- Third attempt (if needed): $50
Once enrolled, you have 180 days to complete your first attempt and 90 days to complete each retake.
What's always included: Both routes include free access to Biotility's BACE Practice Exam Course on UF e-Learning — two full practice exam versions, a math skills module, and category-level self-assessments — plus your digital credential upon passing.
Some third-party providers, like the University of Cincinnati's bootcamp-plus-exam bundle (~$499), charge more because the fee covers instruction time on top of the exam itself, not the BACE fee alone. Registering directly with Biotility/UF is the cheapest path if you just need the credential.
BACE Exam Study Guide
Here's what actually moves the needle, prioritized by impact.
1. Start with the Official Practice Exam Course
Before anything else, enroll in Biotility's free BACE Practice Exam Course. It includes two full-length practice exams (versions A and B), a math module, and category-level self-assessment surveys that tell you exactly where your gaps are. Take the practice exams under timed, exam-like conditions. Your scores will tell you where to spend the rest of your study time.
2. Take the Math Section Seriously
The Applied Mathematics section is the most common reason candidates fall short of 80% on the first attempt. Do not underestimate it.
Work through practice problems for every calculation type until they're automatic — serial dilutions step by step, C₁V₁ = C₂V₂ for making working solutions, molarity from scratch, and all three forms of percent concentration. The math is not hard, but it has to be right, and it has to be fast.
3. Master Aseptic Technique
Aseptic technique threads through multiple categories — Technical Skills, Biotechnology Skills, and scenario questions across the exam. Know the correct operation of biological safety cabinets, autoclaves (121°C, 15 psi, 20–30 min), sterile field protocol, and common sources of contamination. This topic disproportionately rewards the time you put into it.
4. Fill Your Regulation and Quality Gaps
If your background is academic rather than industry, the QA/QC and cGMP section may feel foreign. Learn the difference between Quality Assurance and Quality Control, what makes a proper SOP, how batch records work, and why single strikethroughs (not erasures) are the correct way to correct lab notebook entries. The recommended reference is: Pruitt, H. (2024). Regulatory Compliance and Quality Systems Overview. Biotility, University of Florida.
5. Know Your Equipment Mechanically
Don't just know what equipment is called — know how to set a P200 micropipette, what the Beer-Lambert Law tells you and how to blank a spectrophotometer, why you balance centrifuge tubes, and what denaturation/annealing/extension temperatures mean in a PCR run. Equipment questions also show up embedded in Skills-category scenarios.
6. Do Hands-On Practice if You Can
One or two sessions of actual bench work before the exam makes a measurable difference. Pipette water onto a balance to check your accuracy. Set up a gel. Practice working with sterile containers. This grounds conceptual knowledge in real physical experience, which matters when scenarios ask you to make a judgment call in a realistic lab situation.

After You Pass
Digital Credential & Verification
Passing earns you a verifiable digital credential, issued through Accredible. You can add it to your LinkedIn profile, resume, or email signature with a direct verification link. Employers can independently confirm it's real using Accredible's Credential Verification Tool — by credential URL, Credential ID number, or by uploading the badge image. If you ever lose access to your credential, Accredible has a self-serve retrieval tool tied to the email you registered with.
Credential Validity — 5 Years
The BACE credential is valid for five years from the date you pass. To keep it current, you'll need to retake and pass the exam again before the five-year mark — Biotility frames this as a way to make sure your skills and knowledge stay current in a fast-moving field. It's worth putting a reminder on your calendar well before your credential expires.
Biotility Spotlight Registry
Opt in to the Biotility Credential Spotlight Registry and your credential becomes visible to biotech employers searching for qualified candidates nationwide. It's free and takes about two minutes.
Florida Credit Hours
If you're in Florida, passing the BACE earns you three postsecondary credit hours in any Associate of Science Biotechnology program at a Florida state college — a tangible head start if you plan to pursue an A.S. degree.
Careers and Salary
The BACE credential is recognized by 85+ biotechnology companies (per Biotility's employer directory) and is formally adopted as a state-level credential in 20 states and Washington D.C. — with active use, short of formal adoption, in 17 additional states. That's 37 states plus D.C. where the BACE shows up in some form. Biotility passed its 10,000th credential earner nationally in 2025, and that number keeps climbing. Pay for entry-level lab roles varies a fair amount depending on exactly what title a job posting uses, but the range holds fairly steady: ZipRecruiter puts the U.S. average for a "Biotechnician" title at roughly $42,000/year and for the broader "Entry Level Biotechnology" category at roughly $48,600–$54,600/year as of August 2026, with a realistic entry-level band of about $35,000 to $65,000 depending on title, employer, and location. In major biotech hubs — San Francisco, Boston/Cambridge, San Diego, the Research Triangle in North Carolina — salaries run meaningfully higher than the national average.
The BACE won't set your salary on its own, but it gives employers a verifiable signal of competency that makes you a stronger candidate for those entry-level roles, especially without a completed four-year degree.
Biotility's adoption map has grown quickly. Formally adopted (20 states + D.C.): Washington, Oregon, Arizona, Colorado, Kansas, Oklahoma, Texas, Iowa, Missouri, Arkansas, Michigan, Ohio, Tennessee, Alabama, West Virginia, Virginia, Maryland, D.C., South Carolina, Georgia, and Florida. In active use without formal adoption (17 states): Alaska, California, Nevada, Montana, Utah, Nebraska, Wisconsin, Illinois, Indiana, Kentucky, New Hampshire, New York, Massachusetts, Rhode Island, Pennsylvania, New Jersey, and North Carolina. A further 13 states plus Puerto Rico are listed as "prospective." Check Biotility's adoption map for the most current version — state adoption is one of the fastest-moving facts about this credential, and it only grows over time.
Beyond BACE: A Growing Credential Family
If you're mapping out a longer career path, it's worth knowing the BACE isn't Biotility's only credential anymore. Building on 20 years of BACE, Biotility has started rolling out a small suite of adjacent industry credentials for more specialized roles: the Aseptic Processing Technician Credential (APTC) is already live (75 questions, 2-hour exam, $215 fee, same 80% passing score and 5-year validity as the BACE), aimed at cleanroom and sterile-manufacturing roles. Biotility has also been developing a Closed System Processing Technician credential and an IRB Specialist credential, both still in the exam-development and item-review stage as of mid-2026. None of these replace the BACE — they sit above it as options for candidates who already have a BACE (or equivalent) and want to specialize into aseptic or closed-system manufacturing work. Worth bookmarking if BACE is your first credential rather than your last.

Final Thoughts
The BACE is the clearest way to tell a biotech employer you can do the job before you've had the job. It bridges the gap between classroom training and what the industry actually needs — and it does it with a third-party, employer-validated credential that doesn't require years of experience first.
The 80% bar is real, and the math section isn't trivial. But the path is completely clear: use Biotility's free practice resources, take applied math seriously, get hands-on lab time if you can, and approach the exam the same way you'd approach a real bench protocol — with precision and attention to detail.
