Arrival & Check-In
What happens
You check in at the business centre reception under the name on your booking — there is no polygraph signage anywhere, for your privacy. Reception shows you to a private waiting area; your examiner meets you there and verifies your photo ID before anything begins.
Your part
- Bring a valid government photo ID and your confirmation
- Arrive rested — not rushed, not caffeinated
- A support person may wait in reception
Pre-Test Interview
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
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
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
What it contains
- The methodology and technique used
- Every question asked, verbatim
- The recorded physiological data
- The examiner’s professional conclusions
Confidentiality
Results are shared only with you unless you authorise otherwise in writing. Reports are suitable for attorneys and, where your matter requires it, prepared with legal proceedings in mind.
- Pre-test consultation (30–45 min) — all questions reviewed and agreed before the test begins
- Full polygraph examination — questions repeated minimum 3 times for accuracy using digital instruments
- Post-test review — examiner discusses preliminary findings with you
- Detailed written report — methodology, question-by-question results, physiological data, and professional conclusions
- Private testing venue — discreet, climate-controlled suite at 2564 US-1, Lawrence Township, NJ 08648
- Professional examiner trained to APA standards — vetted and experienced

Getting to the Trenton Office
The office is in a small standalone office building (the HBK Building) fronting directly on US-1 / Brunswick Pike in Lawrence Township, between Trenton and Princeton and close to Quaker Bridge Mall. Arrive by car — this is a divided stretch of Route 1, so expect New Jersey jughandle turns rather than direct left turns when approaching the building.
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.
Travelling From a Nearby City?
This office regularly serves clients travelling from surrounding cities without a local examiner. Each entry below shows the distance, estimated driving time, and turn-by-turn directions from that city to our Trenton office at 2564 US-1, Lawrence Township, NJ 08648. Allow extra travel time on the day — arriving rushed can affect your physiological baseline.
How to Prepare
- Get a full night’s sleep — fatigue affects physiological responses and concentration
- Eat a light meal beforehand; the appointment lasts up to 2 hours
- Avoid excessive caffeine, energy drinks, and nicotine on the day
- Take prescribed medication as normal and tell your examiner what you take
- Wear comfortable clothing — sensors are placed on your upper body
What to Bring
- A valid government-issued photo ID — your identity is verified before testing
- Your booking confirmation
- Any relevant documents or case notes for your examiner
- A written list of the questions or concerns you want addressed
- Glasses or hearing aids, if you use them
What Not to Do
- × Do not drink alcohol or take non-prescribed drugs in the 24 hours before your test
- × Do not stop prescribed medication — changing your routine skews your baseline
- × Do not arrive sleep-deprived, unwell, or rushed
- × Do not attempt countermeasures — they are detectable and can invalidate your result
- × Do not bring children into the session; an adult support person may wait in reception
When Testing Cannot Go Ahead
- × If you are under the influence of alcohol or non-prescribed drugs on the day
- × If you are severely ill, exhausted, or in significant pain
- × If a medical condition makes testing unsuitable without physician clearance
- × If you are under 18, or required consent is missing
- × If the examiner’s case review finds the matter unsuitable — your $100 deposit is refunded in full

Why This Matters — What a Professional Examiner Looks Like
Polygraph Testing in Trenton — What to Know
One practical point first: although this page serves Trenton, testing takes place just north of the city at 2564 US-1 in Lawrence Township — a deliberate choice, since many capital-area clients specifically do not want to be seen entering an office near the State House, the courthouses, or their own agency. The Business Route 1 location lets state workers, court staff, and downtown professionals attend a discreet appointment fifteen minutes from their desks without being anywhere colleagues walk at lunch. A single-issue examination for Trenton clients is $600.
The capital shapes the caseload. Alongside the usual run of fidelity and family disputes from Hamilton, Ewing, and the city's own neighbourhoods, the office sees a distinctive share of clients whose problems touch public life: employees answering internal allegations, contractors in disputes over tender conduct, and people whose family court matters in the Mercer Vicinage have escalated to serious cross-accusations.
Because so many Trenton cases run parallel to formal proceedings, examinations here are often coordinated with attorneys — questions reviewed in advance, reports released under privilege, timing matched to hearing dates. Clients booking directly are treated with the same rigour: an examiner trained to American Polygraph Association standards is individually assigned once the $100 deposit confirms the appointment, and the balance is simply paid on the day.

Beware of Unqualified Examiners

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.
