Pre-Test Interview

Every question agreed before anything is asked
30–45 minutes

What happens

Your examiner explains the entire procedure and the instruments, completes your consent paperwork, and conducts a psychophysiological suitability assessment — covering health, medication, and sleep. Then, together, you review and agree the exact wording of every test question. Nothing asked during the examination will be a surprise.

Your part

  • Be open about medications and health conditions
  • Raise anything you want asked — this is the moment
  • Ask questions until you are fully comfortable

The Examination

Validated APA-standard techniques, one-to-one in a private room
Approx. 90 minutes

What happens

Sensors are placed on your upper body and connected to a government-grade computerised instrument. You answer the agreed yes-or-no questions while four physiological channels are recorded. Each question is repeated a minimum of 3 times across multiple charts — a single reaction never decides a result.

What the instrument records

  • Cardiovascular activity — heart rate & blood pressure
  • Electrodermal activity — skin conductivity
  • Thoracic & abdominal respiration
  • Movement & timing, chart by chart

Analysis & Verbal Result

Before you leave the office
Same day

What happens

The examiner scores your charts using standardised numerical scoring, explains what the data shows, and discusses the preliminary outcome with you in the post-test review. You leave knowing your result — not waiting for a letter.

Your part

  • Ask anything about how the result was reached
  • Discuss next steps if the matter is ongoing

Your Written Report

Travelling Far? Arrive the Night Before

If your journey is more than about two hours, we strongly recommend travelling the evening before and staying near the office. A full night’s sleep is not just comfort — fatigue measurably affects the physiological responses the polygraph records, and a rested examinee produces a cleaner, more reliable chart. Book a morning appointment, sleep 7–8 hours, have a light breakfast, and arrive unhurried.

Membership binds an examiner to a professional code of ethics, continuing education, and peer accountability.

How you meet your examiner: after you book online, an examiner is individually assigned to you based on your case details, test type and preferred dates — examiners are matched to the client and the case, never to an office. Your examiner then contacts you directly, and you receive their full details with your confirmation. For security and impartiality we do not publish examiners’ names online. Read more about our examiners and the standards they work to.

Examiner Licensing in Delaware

Delaware does not license polygraph examiners Delaware has no state licensing requirement for polygraph examiners — anyone can legally offer testing. That makes verifying an examiner’s training, professional membership, and published standards essential before you book with anyone. The recognised benchmarks are graduation from an APA-accredited training program and membership of the American Polygraph Association. A directory of states that do license examiners is maintained by the APA.

Local Briefing

Polygraph Testing in Wilmington — What to Know

Wilmington's polygraph clientele is unlike almost any other city its size, because Wilmington itself is unlike any other city its size. The North West Street office sits within walking distance of the Rodney Square legal district, and a meaningful share of bookings arrive through attorneys: credibility checks before depositions, verification of a client's account ahead of settlement talks, and internal corporate matters that in-house counsel would rather resolve quietly than escalate. When a dispute involves a Delaware-registered entity, the people involved are often here anyway — the examination simply gets added to the trip.

Private cases follow the more familiar pattern, with a local twist. Fidelity and relationship examinations remain the single most common booking among residents of Trolley Square, the Riverfront and the surrounding New Castle County suburbs, but Wilmington also produces a steady stream of financial-trust cases — disputes between business partners, questions over the handling of family money, and accusations traded between co-owners of small firms along the Concord Pike and Kirkwood Highway corridors.

A single-issue examination in Wilmington is $750, with only a $100 deposit required to reserve a time and the remainder paid on the day. The examiner handling your appointment is chosen for your particular case after booking, and the downtown location means clients from Newark, New Castle and even Philadelphia's southern suburbs can attend within a half-hour drive via I-95.

FAQ

Frequently Asked Questions — Wilmington

How much does a lie detector test cost in Wilmington?
A single person polygraph examination in Wilmington starts from $750, all-inclusive. Couples testing is $1,400 and group testing (3+ people) is $700 per person. All prices include the booking fee, examination, pre-test assessment, and a detailed written report. No hidden costs.
Where exactly is the Wilmington testing venue?
Our Wilmington venue is located at 1000 N West St, Wilmington, DE 19801. It is a professional, private office environment. The exact suite or floor details, along with parking information and directions, are sent to you via SMS and email after your booking is confirmed.
How do I book a lie detector test in Wilmington?
All bookings are made through our secure online booking system. Select Delaware as your region, choose Wilmington as your location, pick your preferred date and time, and confirm your details. Only a $100 deposit is required. You'll receive SMS and email confirmation.
Do Delaware courts accept polygraph evidence?
As a rule, no — Delaware courts treat polygraph results as inadmissible at trial. Their practical power in Wilmington lies upstream of the courtroom: attorneys use passed examinations to strengthen negotiating positions, support plea discussions, or persuade an opposing party that an accusation will not hold. If your goal is legal, involve your lawyer before booking so the test question is framed usefully.
Can my company require employees to take a polygraph over missing funds?
For most private employers the federal Employee Polygraph Protection Act makes compulsory testing unlawful, with narrow exceptions for specific ongoing-loss investigations that follow strict notice rules. What we routinely see in Wilmington's corporate environment instead is voluntary testing: an accused employee commissions their own examination to clear their name, which the law fully permits.
Is the North West Street location discreet enough for a high-profile professional?
Yes. Wilmington is a small legal community where reputations travel fast, and the office is run accordingly — no signage referencing polygraph, single-client scheduling so you never share a waiting area, and results released to no one but you without written instruction. Many clients here are attorneys, executives or public figures, and the process is built around that reality.
Can I reschedule or cancel?
Yes. Please contact us at least 48 hours before your appointment to reschedule. We'll work with you to find a new date and time. Full cancellation and rescheduling policies are included in your booking confirmation email.

Beware of Unqualified Examiners

The accuracy of a lie detector test depends on the skill of the examiner, not the machine. Unfortunately, unqualified individuals operating without accreditation continue to damage the industry’s reputation and deliver unreliable results. Always verify your examiner graduated from an APA-approved school and uses validated testing protocols.

Verify the training Ask which APA-accredited school the examiner graduated from and how many hours of formal training they completed — the recognised minimum is 400.
Ask for written standards A professional operation publishes its code of ethics and standards of practice. Read ours here — and ask any competitor for theirs.
Check the venue Accurate testing requires a controlled office environment. Be cautious of examiners who only offer testing in homes, hotel rooms, or cars.
Watch for warning signs Prices far below market rate, guaranteed results, or no pre-test process are red flags. Read our fraud alerts before paying anyone a deposit.
