ASCP vs. AMT Certification for Lab Technicians: Which One Should You Choose?
By Dr. Zubair Khalid, DVM, MS, PhD ·
Quick Answer
- ASCP certification is the more widely recognized credential for medical laboratory scientists and technicians, with most hospital employers listing it as a preferred or required qualification.
- AMT certification offers an alternative pathway that may be more accessible for some candidates, particularly those with different educational backgrounds or who need flexibility in exam scheduling.
- Neither certification guarantees employment, and state licensure requirements, employer preferences, and regional job markets can override the value of either credential.
Understanding the Two Major Certifying Bodies
The American Society for Clinical Pathology (ASCP) and American Medical Technologists (AMT) both certify laboratory professionals, but they operate as separate organizations with distinct histories, eligibility requirements, and examination processes. For a laboratory technician or medical laboratory scientist, the choice between these two credentials affects job applications, career mobility, and professional development.
The Occupational Outlook Handbook from the U.S. Bureau of Labor Statistics describes clinical laboratory technologists and technicians as professionals who perform tests on body fluids, tissues, and other specimens to help diagnose and treat disease. The handbook notes that most clinical laboratory technologists hold a bachelor's degree, while clinical laboratory technicians typically complete an associate's degree or a certificate program. Both ASCP and AMT certifications serve as professional credentials that verify a candidate has met specific educational and examination standards.
ASCP is the larger and older organization, with a Board of Certification that administers examinations for multiple laboratory specialties. AMT was established to provide certification for medical laboratory personnel and also certifies other allied health professionals. The two organizations maintain separate eligibility requirements, exam formats, and continuing education obligations.
Historical Context and Organizational Focus
ASCP has its roots in pathology and has historically maintained close ties with academic medical centers and hospital laboratories. The organization's certification board develops examinations that align with the curriculum of accredited medical laboratory science programs. Many hospital human resources departments recognize ASCP certification as the standard credential for laboratory positions.
AMT began as a certifying body for medical technologists and has expanded to include medical laboratory technicians, phlebotomists, and other allied health professionals. The organization positions itself as a career-long certification partner, with a focus on professional development and continuing education. AMT certification is recognized in most states, though some employers may view it as less familiar than ASCP.
Eligibility Requirements Compared
ASCP Eligibility Pathways
ASCP offers multiple routes to eligibility for the Medical Laboratory Scientist (MLS) and Medical Laboratory Technician (MLT) examinations. The most common pathway requires graduation from a National Accrediting Agency for Clinical Laboratory Sciences (NAACLS) accredited program. Candidates must also complete a clinical rotation or work experience component.
For the MLS certification, candidates typically need a bachelor's degree from an accredited program. For the MLT certification, an associate degree from an accredited program is the standard requirement. ASCP also offers alternative pathways for candidates with degrees in other sciences who have completed specific coursework and laboratory experience.
AMT Eligibility Pathways
AMT has its own eligibility requirements for the Medical Laboratory Scientist (MLS) and Medical Laboratory Technician (MLT) credentials. The organization accepts graduates from accredited programs and also offers pathways for candidates with relevant work experience. AMT may be more flexible in accepting candidates who have completed non-traditional education routes.
Candidates who have worked in a laboratory for a specified number of years may qualify for AMT certification without completing a formal accredited program. This experience-based pathway can be valuable for technicians who entered the field through on-the-job training or who have military laboratory experience.
Examination Format and Difficulty
ASCP Examination Structure
The ASCP Board of Certification examinations are computer-based and use a multiple-choice format. The MLS and MLT exams cover content areas including blood banking, chemistry, hematology, immunology, microbiology, and laboratory operations. The exam includes questions that test both theoretical knowledge and practical application.
ASCP examinations are known for their rigor and for the depth of content they cover. Candidates who have completed accredited programs typically have the best preparation for the exam. The ASCP exam is scored on a pass or fail basis, and candidates who do not pass may retake the exam after a waiting period.
AMT Examination Structure
The AMT certification examinations are also computer-based and cover similar content areas to the ASCP exams. The AMT exams include questions on clinical chemistry, hematology, immunology, microbiology, and other laboratory disciplines. The format and difficulty of the AMT exam are comparable to the ASCP exam in many respects.
Some candidates report that the AMT exam is slightly less difficult than the ASCP exam, but this perception is not universal. The actual difficulty depends on the candidate's educational background and preparation. Both organizations provide study materials and practice examinations to help candidates prepare.
Recognition and Employer Preferences
Hospital and Clinical Laboratory Preferences
The Occupational Outlook Handbook notes that clinical laboratory technicians and technologists work primarily in hospitals, diagnostic laboratories, and physicians' offices. In these settings, ASCP certification is often the preferred credential. Many hospital job postings list ASCP certification as a requirement or a preferred qualification.
AMT certification is also recognized in hospital settings, but some employers may be less familiar with it. In regions where AMT has a strong presence, the credential may be equally accepted. Job seekers should review the specific requirements of each employer and consider the preferences of the local job market.
State Licensure Requirements
Some states require laboratory personnel to hold a license in addition to certification. The licensure requirements vary by state, and some states accept either ASCP or AMT certification as a pathway to licensure. Other states may have specific requirements that favor one certification over the other.
Candidates should research the licensure requirements in the state where they plan to work. The O*NET OnLine database provides information about the work context and requirements for clinical laboratory technologists and technicians, which can help candidates understand the expectations in their region.
Cost and Renewal
ASCP Certification Costs
The ASCP certification examination has an application fee that candidates must pay when they submit their application. The fee covers the cost of the examination and the initial certification. ASCP certification must be renewed periodically, and the renewal process requires continuing education credits.
The cost of ASCP certification includes the application fee, the exam fee, and the cost of any study materials. Candidates who need to retake the exam must pay the exam fee again. The renewal fee is separate from the initial certification fee.
AMT Certification Costs
The AMT certification examination also has an application fee and an exam fee. The costs are generally comparable to the ASCP fees, though the exact amounts may differ. AMT certification also requires renewal, and the renewal process includes continuing education requirements.
Candidates should compare the total cost of certification, including the initial fees and the ongoing renewal costs, when deciding between ASCP and AMT. The cost difference is not likely to be the deciding factor for most candidates, but it is a practical consideration.
Career Advancement and Continuing Education
ASCP Continuing Education Requirements
ASCP certification requires continuing education credits for renewal. The certification maintenance program requires a certain number of credits over a specified period. The credits can be earned through professional development activities, such as attending conferences, completing online courses, or publishing articles.
The ASCP also offers additional certifications in specialty areas, such as molecular biology, cytogenetics, and histotechnology. These specialty certifications can enhance a technician's career prospects and demonstrate advanced knowledge in a specific area.
AMT Continuing Education Requirements
AMT certification also requires continuing education credits for renewal. The AMT continuing education program is designed to help certified professionals stay current with advances in laboratory science. The credits can be earned through similar activities as ASCP.
AMT also offers specialty certifications in areas such as phlebotomy and medical laboratory assistant. These credentials can be valuable for technicians who want to expand their skills and career options.
Job Market and Employment Outcomes
Employment Outlook for Laboratory Professionals
The Occupational Outlook Handbook projects that employment of clinical laboratory technologists and technicians will grow in the coming years. The demand for laboratory services is expected to increase as the population ages and as medical testing becomes more common. This growth suggests that both ASCP and AMT certified professionals will have job opportunities.
The job market for laboratory professionals varies by region and by the type of employer. Hospitals and large diagnostic laboratories tend to have the highest demand for certified technicians. Rural areas may have fewer job opportunities but may also have less competition for positions.
Employer Preferences
Employer preferences for ASCP or AMT certification can vary by region and by the type of facility. Academic medical centers and large hospitals may prefer ASCP certification because of its long history and its association with accredited education programs. Smaller laboratories and clinics may be more flexible and accept either certification.
Job seekers should research the preferences of employers in their target job market. The O*NET database provides information about the tasks, skills, and work context for medical laboratory technologists and technicians, which can help candidates understand the expectations of the role.
Practical Steps for Choosing a Certification
Step 1: Review Your Educational Background
The first step in choosing a certification is to review your educational background. If you have graduated from a NAACLS accredited program, you may be eligible for both ASCP and AMT certification. If you have a degree in a related field, you may need to check the eligibility requirements for each organization.
Candidates who have completed a non-traditional education pathway may find that AMT offers a more accessible route to certification. The experience-based pathway can be valuable for technicians who have worked in the field without a formal degree.
Step 2: Research State Licensure Requirements
The next step is to research the licensure requirements in the state where you plan to work. Some states require laboratory personnel to hold a specific certification, while others accept either ASCP or AMT. The state licensure board can provide information about the specific requirements.
Candidates who plan to work in multiple states should consider the certification that is recognized in the most states. ASCP certification is generally recognized in more states, but AMT certification is also widely accepted.
Step 3: Review Employer Job Postings
Reviewing job postings in your target job market can provide insight into employer preferences. Many job postings will specify the certification that is required or preferred. Candidates should look for patterns in the job postings to understand the local market.
The Occupational Outlook Handbook provides information about the work settings and employment outlook for clinical laboratory technologists and technicians. This information can help candidates understand the types of employers that are hiring in their area.
Step 4: Compare the Costs and Requirements
Compare the costs and requirements of each certification. The application fees, exam fees, and renewal fees are similar for both organizations. The continuing education requirements are also comparable. The decision may come down to the recognition of the certification in your target job market.
Step 5: Consider Your Career Goals
Your career goals should also influence your decision. If you plan to pursue a specialty certification or advance into a management role, you should consider which certification will support your career path. Both ASCP and AMT offer specialty certifications, but the options may differ.

Common Failure Patterns in Certification Decisions
Choosing a Certification Without Researching the Local Market
A common mistake is choosing a certification without researching the preferences of employers in the target job market. A candidate who chooses ASCP certification but plans to work in a region where AMT is the preferred credential may face a disadvantage in the job search.
Ignoring State Licensure Requirements
Another common failure is ignoring the state licensure requirements. A candidate who chooses a certification that does not meet the state licensure requirements may be unable to work in that state. The state licensure requirements should be checked before choosing a certification.
Underestimating the Cost of Certification
The cost of certification includes the application fee, the exam fee, and the renewal fees. A candidate who underestimates the cost may be unprepared for the financial commitment. The cost of certification should be included in the career planning.
Failing to Prepare for the Exam
The certification exam is rigorous, and candidates who fail to prepare may not pass. The exam preparation should include a review of the content areas and practice with sample questions. The study materials provided by the certification organizations can help candidates prepare.
Records and Measurements
Tracking Certification Status
Certified professionals should track their certification status, including the expiration date and the continuing education credits earned. The certification body provides a record of the certification status, and the professional should keep a copy of the certificate and the renewal records.
Documenting Continuing Education
The continuing education credits should be documented and kept in a file. The documentation should include the date of the activity, the provider, and the number of credits earned. The documentation may be requested by the certification body during the renewal process.
Monitoring Job Market Trends
The job market for laboratory technicians can change over time. The Occupational Outlook Handbook provides information about the employment outlook for clinical laboratory technologists and technicians. The O*NET database provides information about the tasks, skills, and work context for the occupation.
Safety and Regulatory Context
Laboratory Safety
Laboratory technicians work with biological samples and chemicals, and safety is a critical concern. The Occupational Outlook Handbook notes that clinical laboratory technologists and technicians must follow safety procedures to prevent contamination and injury. The certification process includes training in laboratory safety.
Regulatory Requirements
The regulatory requirements for laboratory personnel vary by state and by the type of laboratory. The certification is a credential that verifies the professional has met the required standards. The regulatory requirements should be checked with the state licensure board.
Professional Escalation Criteria
When to Seek Additional Guidance
Candidates who are unsure about the certification decision should seek additional guidance from a career counselor, a mentor, or a professional organization. The American Society for Microbiology provides career development resources for microbiology professionals, and the Association of American Veterinary Medical Colleges provides career resources for veterinary professionals. These resources can help candidates understand the career paths and the certification requirements.
When to Contact the Certification Body
Candidates who have questions about the eligibility requirements or the exam should contact the certification body directly. The certification body can provide the most accurate information about the requirements and the exam.
Building a Certification Decision Scorecard for Your Specific Job Market
Comparing ASCP and AMT on general reputation or exam format only takes you so far. The credential that serves you best depends on the specific employers, state rules, and career path you target. A structured scorecard turns that comparison into a repeatable decision process you can apply to any job market or career change.
Step 1: Define Your Target Work Settings
Start by listing the types of employers you will apply to. The Occupational Outlook Handbook identifies hospitals, diagnostic laboratories, and physicians' offices as the primary work settings for clinical laboratory technologists and technicians. Each setting has different hiring norms.
Write down your target settings in rank order. For example, a candidate might list a regional hospital first, a reference laboratory second, and a clinic third. This ranking matters because a credential that works for a hospital may not be the same one a clinic prioritizes.
Step 2: Collect Employer Preference Data
For each target employer type, gather evidence from actual job postings. Look at 10 to 15 postings per employer type in your geographic area. Record whether each posting lists ASCP, AMT, both, or neither as a requirement or preference. Also note whether the posting says "or equivalent" after a certification name, because that phrase signals flexibility.
The O*NET OnLine database can help you understand the tasks and work context for medical laboratory technologists and technicians in different settings. Use that information to anticipate which employers emphasize formal credentials versus demonstrated skills.
Step 3: Build the Scorecard
Create a table with one row for each employer type and one column for each certification. For each cell, assign a score based on your job posting research. Use a simple scale of 0 to 2, where 0 means the posting does not mention the credential, 1 means it is listed as preferred, and 2 means it is listed as required. Add a third column for state licensure acceptance in your state, using the same scale.
Multiply each score by the weight you assigned to that employer type in Step 1. Sum the weighted scores for ASCP and AMT separately. The higher total indicates which certification aligns better with your specific job market. This method converts anecdotal impressions into a documented comparison you can revisit as the market changes.
Step 4: Record Your Evidence
Keep a simple spreadsheet or notebook with the following columns for each job posting you review: date reviewed, employer name, employer type, certification listed, whether it was required or preferred, and the posting source or link. This record serves two purposes. First, it gives you a defensible basis for your certification choice. Second, it becomes a reference you can update when you search for a new job later in your career.
The American Society for Microbiology career resources include guidance on professional development and networking that can help you verify your scorecard findings. Talking to working technicians in your area can confirm whether the job posting patterns match the actual hiring practices.
Step 5: Reassess at Career Milestones
Your scorecard is not a one-time decision tool. Rebuild it when you change states, when you pursue a specialty certification, or when you apply for a promotion. A credential that fits a hospital bench position may not carry the same weight for a laboratory supervisor role or a position in a different state.
The Occupational Outlook Handbook notes that employment of clinical laboratory technologists and technicians is projected to grow, which means new employers will enter your market over time. Re-running the scorecard every two to three years keeps your certification strategy aligned with the current market.
Common Failure Patterns in the Scorecard Approach
Using National Trends Instead of Local Data
A candidate who relies on the general reputation of ASCP without checking local postings may miss a regional market where AMT is the standard. The scorecard only works when you feed it local evidence.
Ignoring the "Equivalent Certification" Clause
Some job postings list ASCP but add "or equivalent certification" in the text. Candidates who see only the ASCP name and skip the posting may underestimate their options. Read the full qualification section of each posting before scoring it.
Failing to Update the Scorecard
A scorecard built once and never revisited becomes stale. Employer preferences shift with staffing shortages, new laboratory directors, and changes in state rules. Schedule a review of your scorecard when you renew your certification or when you start a job search.
Overweighting a Single Employer
If one large hospital dominates your target market, its preferences may skew your scorecard. That is acceptable if you genuinely want to work there, but it is a limitation you should note in your records. If you are open to multiple employers, weight your employer types more evenly.
Records and Measurements
Keep your scorecard in a format you can update easily. A spreadsheet with columns for employer type, certification score, and weight works well. Store the job posting URLs in the same file so you can verify your scoring later. Update the scorecard at least once per year or whenever you begin a new job search.
The National Science Foundation careers page shows how federal research organizations describe technical roles and their qualification expectations. Reviewing such postings can help you understand how certification language appears in different employment sectors, including government laboratories that may have their own hiring rules.
Professional Escalation Criteria
If your scorecard shows a clear preference for one certification but you are not eligible for that credential, contact the certification body directly to ask about alternative eligibility pathways. If you find conflicting information between job postings and state licensure rules, contact the state licensure board before you pay any application fees. If you are early in your education and have not yet chosen a program, the National Institutes of Health Office of Intramural Training and Education offers professional development resources that can help you understand how laboratory careers progress and what credentials matter at different stages.
