Not Every Lie Detection Service Advertised in Maryland Is Legitimate
Read this if you're looking for any lie detection service in Maryland. It could save you time, money, and a lot of unnecessary stress.
If you're searching for a lie detector test in Maryland for the first time, you're probably facing an important decision
— whether it involves a relationship, a legal matter, or a professional dispute. The result of your polygraph test may shape what happens next, so the accuracy and legitimacy of the service you choose genuinely matters.
Unfortunately, not every company advertising "lie detection" in Maryland is offering a scientifically validated service. Some use unproven alternative techniques — voice stress analysis, EEG-based methods, or eye-tracking — that have no peer-reviewed research confirming their accuracy. Others may use real polygraph equipment but employ unqualified or uncertified examiners who haven't completed accredited training. These shortcuts produce unreliable results that can lead to the wrong conclusions at the worst possible time.
Here's what a legitimate polygraph service looks like: a computerized polygraph instrument operated by an examiner who graduated from an APA-accredited school, completed a supervised internship, passed background and criminal history checks, and holds any required state licence.
While Maryland does not require a separate state polygraph licence, our examiners still meet the same rigorous standards we enforce across our entire network — as defined in our Standards of Practice.
Certified examiners are also required to complete a minimum of 30 hours of continuing education every two years to stay current with evolving research and methodology. Every examiner in our network meets these requirements — we verify credentials independently, conduct ongoing quality reviews, and require full adherence to our Code of Ethics and Standards of Practice. Under these conditions, peer-reviewed research confirms accuracy rates of up to 95% for single-issue examinations.
Ask if the examiner is APA-accredited — if they can't confirm, walk away
Verify they use a computerized polygraph — not voice analysis or alternatives
Check their continuing education — 30 hours every 2 years is the standard
Request a written report with scoring — credible examiners always provide one
Travelling to your polygraph appointment? These tips will help you arrive prepared and get the most accurate results.
Plan Your Journey
Your appointment at our Towson office is approximately ~1 hr 15 min from Frederick. We recommend arriving 10–15 minutes early — rushing to your appointment can elevate your heart rate and affect your physiological baseline, which could impact accuracy. Plan for traffic and allow a small buffer.
The Night Before
Get a full night's rest. Fatigue affects physiological responses and can interfere with the accuracy of your polygraph results. Avoid alcohol the evening before, and try to maintain your normal routine as much as possible.
On the Day
Avoid caffeine and stimulants — coffee, energy drinks, and nicotine elevate heart rate and can affect sensor readings
Eat a light meal — don't arrive on an empty stomach as sessions typically last 90 minutes to 2 hours
Wear comfortable clothing — sensors are placed around the upper body, so avoid tight or restrictive layers
Bring valid photo ID — your examiner will verify your identity before the examination begins
What to Bring
Bring any relevant documents — case notes, a list of questions you want covered, or reference materials. If someone is accompanying you, they're welcome to wait in reception while the examination takes place in a separate private room.
