For employers in sensitive sectors, choosing a polygraph exam is a big deal. A good test is accurate 90 to 95 percent of the time. But, picking the wrong provider can risk your organization’s safety.
The law, the Employee Polygraph Protection Act (EPPA), limits most private employers. Yet, some groups like government agencies and security firms can use polygraphs. This makes choosing a vendor a key step to follow the law.
Choosing the right polygraph service can make a big difference. It turns the polygraph into a key tool for making better hiring decisions. Your service selection affects the quality of the information you get.
Here are some key points to help you choose the right polygraph service. A skilled polygraph examiner is essential for your success.
Criteria for Selecting a Polygraph Service
Choosing a polygraph service is a big decision. It’s not just about finding one online. You need to check if the examiner is well-trained, up-to-date, and follows the best practices.
The first thing to look at is the examiner’s education. A certified examiner should have graduated from a school approved by the American Polygraph Association (APA). This ensures they know the science behind polygraph tests.
Experience is also key, but it must be relevant. Check if the examiner has the right experience for your case. For example, someone with lots of experience in pre-employment screening might not be the best for investigating theft.
It’s important that the examiner keeps learning. Polygraphy is a field that changes. Good examiners stay up-to-date by joining organizations like the APA, AAPP, or NPA. These groups require them to keep learning.
Make sure the service is licensed to operate in your area. A reputable service will have all the necessary licenses. This shows they are professional and follow the law.
Look for a service that lets you review the exam charts. This means another expert checks the test data. It shows they are open and serious about their work.
Modern polygraph services use digital equipment. This equipment is better at collecting and analyzing data. It also has software to spot countermeasures, which are attempts to cheat the test. Old or analog equipment is a warning sign.
You should get a detailed written report of the findings. A good service will give you a clear report. It should explain the test, the data collected, and the examiner’s conclusion. Don’t settle for just a verbal report.
By following these steps—checking for APA training, relevant experience, professional memberships, licenses, quality control, modern equipment, and written reports—you make a smart choice. This careful approach protects the fairness of your hiring or investigation.
Questions to Ask Your Polygraph Provider
A provider’s first pitch might sound good, but your questions will show their true skills. This is your chance to really check if they’re right for you. Don’t just look at what they say; ask them to prove it.
Start by checking their basic qualifications. Make sure they have the right state license and are certified by the American Polygraph Association (APA). A good provider will have this ready for you. This helps weed out those who aren’t qualified.
Then, ask about the person doing the test. Find out how much experience they have, and if they’ve worked with your type of cases before. Ask, “How many years have your certified examiners been practicing, and what is their specific background?” Experience is key.
It’s also important to understand how they do the test. Look for evidence-based methods, like the APA Model Policy. Ask about the type of test they use and how they write the questions.
| Test Type | Primary Use | Question Focus | Key Consideration |
|---|---|---|---|
| Screening Test | Broad vetting (e.g., pre-employment) | Multiple, generalized issues | Useful for wide nets, but less precise per issue. |
| Specific-Issue Test | Investigating a single, defined incident | One central issue with related control questions | Considered most accurate due to focused scope. |
As the table shows, single-issue tests are more accurate. So, ask, “Do you use a validated specific-issue test format for incident investigations, and how many questions are typically included in the test series?” This checks if they follow the best practices.
Also, ask about what you’ll get back. Will you get a detailed report, and how long will it take? Ask about their quality control too. Do they have a system for checking their work? A good company will have this in place.
Lastly, check their reputation. Ask about their Better Business Bureau rating and get references. A high BBB rating, like the Global Polygraph Network’s A+, is a good sign. It’s important to check their reputation through other sources. This shows the importance of an independent third-party who follows professional standards, not just what you want.
By asking these specific questions, you turn the selection process into a thorough check. You make sure you have certified examiners, check their methods, and look at their reputation. This ensures your polygraph program is trustworthy.
Certification and Accreditation: What They Mean
Accreditation and certification are often mixed up, but they mean different things in polygraph services. Getting them confused can lead to hiring the wrong person. To understand the difference, it’s key to know about accreditation and certification.
Accreditation is like a quality stamp for polygraph schools. The American Polygraph Association (APA) is the top accrediting body. Their stamp means a school meets basic standards for teaching, instructors, and facilities.
This ensures students learn scientifically validated techniques right from the start. The APA works to make sure examiners use proven, reliable methods.
Certification, on the other hand, is a mark of achievement for individuals. The APA gives certification to certified examiners who show they’re skilled. They need to have enough experience and pass tough exams.
Certification also means they keep learning. This keeps examiners up-to-date with new field developments and ethics.
These credentials are more than just symbols. They show an examiner is well-trained and follows strict ethics. If a provider can’t show both school accreditation and individual certification, it’s a big warning sign.
The table below shows the main differences:
| Concept | Applies To | Governing Body | Key Purpose |
|---|---|---|---|
| Accreditation | Polygraph Training Schools & Programs | American Polygraph Association (APA) | Ensures a minimum standard of education and curriculum quality for all students. |
| Certification | Individual Certified Examiners | Professional Organizations (e.g., APA) | Validates an examiner’s personal competency, experience, and commitment to ongoing education and ethics. |
Always check both credentials. Choosing a service with APA-certified examiners from an APA-accredited school is the best sign of quality. This ensures reliable, trustworthy results.
Importance of Examiner Experience
In polygraph testing, an examiner’s reputation is built on their experience. Formal training and certificates are just the start. The real skill comes from thousands of real-world tests.
Being a good examiner is about more than just years of experience. Employers should look at four key areas to see if someone is truly skilled.
| Dimension of Experience | What It Means | Why It Matters to Employers |
|---|---|---|
| Volume | The total number of polygraph exams conducted. | High volume exposes an examiner to a vast range of subject behaviors and case complexities, refining their instinct and technique. |
| Depth | The number of years actively working in the field. | Longevity indicates sustained competence, adaptability to evolving methods, and a deep understanding of the profession’s ethical landscape. |
| Relevance | Specific experience with cases like yours (e.g., pre-employment, specific issue tests). | An examiner familiar with your industry’s unique pressures and question types can design a more effective and targeted test. |
| Recency | Active, regular testing versus sporadic work. | Skills remain sharp. A consistently active examiner is up-to-date on current practices and maintains procedural fluency. |
Michael Martin, owner of the Georgia Polygraph Network, is a great example. With over 40 years and more than 11,000 exams, he shows the value of experience. His work builds a reputation for reliability.
Experienced examiners can handle tough subjects better. They spot subtle attempts to cheat and deal with complex cases. This is something less experienced ones struggle with.
Being court-qualified is also key. If polygraph results might be used in court, an experienced examiner who can testify is essential. They know the standards and can defend their methods.
When you hire a polygraph service, you’re not just getting a test. You’re investing in someone’s judgment. Their experience builds trust and shows they’re reliable. For more on this, check out the role of examiner experience.
