Nearly 110,000 people call West Covina home, making it one of the larger cities in the San Gabriel Valley — a spread of neighbourhoods along the I-10 corridor east of Los Angeles. When residents need a polygraph, the examination itself does not happen in West Covina: our nearest office is in Brea, at 135 S State College Blvd, Brea, CA 92821, 10.7 miles away and roughly a 19 minute drive south into Orange County.
That short hop across the county line is the honest cost of doing this properly. We test in one fixed, controlled environment rather than travelling to clients, because the instruments at the heart of a polygraph record delicate physiological signals that uncontrolled rooms distort. The Brea suite offers what a living room in West Covina cannot: privacy guaranteed, sound managed, seating and setup identical for every person examined.
Your examiner is a professional trained to APA standards, and the appointment runs to a fixed sequence — pre-test interview with all questions agreed in advance, the examination on computerized instrumentation, then on-site scoring of the charts. You leave with a same-day written report rather than a wait. For West Covina clients, a single examination is $700, couples testing is $1,300, and group examinations are $650 per person.

Preparing for Your Visit
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 Brea office is approximately ~19 min from West Covina. 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.
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.
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

Why Our Results Are Trusted
The science behind our polygraph examinations at Brea.
Accuracy Rate
When administered by a qualified, APA-qualified examiner using validated protocols, polygraph testing achieves 90–95% accuracy in specific-issue testing, supported by decades of peer-reviewed research.
Question Repetition
Every relevant question is repeated a minimum of three times during your examination. This multi-pass approach eliminates anomalies and ensures the physiological data is consistent and reliable.
Channels Monitored
Our digital instruments simultaneously monitor heart rate, blood pressure, respiration (thoracic and abdominal), and electrodermal activity — providing a comprehensive physiological profile throughout the examination.
Validated Technology
The polygraph is the only scientifically validated technology for truth verification. We reject unvalidated alternatives including voice stress analysers, mobile apps, and eye-tracking tools.
Polygraph Testing & Legal Admissibility in California
Polygraph results can be used as supporting evidence in many legal proceedings in California.

Our Brea examiners provide detailed written reports suitable for legal use, and are available for expert testimony if required.
