The difference is clear
Before you book a polygraph in Houston, understand what you're comparing. EyeDetect® uses ocular-motor technology — not wires, not blood pressure cuffs — to assess credibility with independently published accuracy rates.

Simple, confidential process
No wires. No blood pressure cuffs. Just you, a screen, and proprietary eye-tracking technology developed by Converus scientists with decades of deception-detection research behind it.
Step 01
Call or complete our intake form. Dr. Walwyn reviews your case and confirms which assessment is right for your situation — individual, criminal defense, or employer-related.
Step 02
You sit in front of a computer screen. The EyeDetect® system tracks subtle, involuntary eye movements as you respond to questions. No touching, no sensors. Takes 30 minutes.
Step 03
Responses are scored by Converus algorithms — not human interpretation. This eliminates examiner bias and produces a credibility score with published accuracy rates of 80–85%.
Step 04
You receive a professional written report the same day. For attorney clients, reports are formatted for court-ready submission and are available electronically within hours.
Clear, all-inclusive pricing
No hidden costs. No deposit games. Every assessment includes the examination, scoring, and a written report. Criminal defense attorneys on MAC panels are billed directly at court-approved rates.
Single-issue credibility assessment. Ideal for individuals, family matters, employment, and attorney-requested testing. In-office at our Houston location.
$250 per assessment
Complete pre-sentence investigation package. Includes EyeDetect® assessment plus full written report formatted for court submission. Used by criminal defense attorneys.

Not all examiners are equal
There are other EyeDetect® providers in the greater Houston area. Here is why Integrity Assessments Investigations stands apart.
IAI is headquartered inside Houston city limits — not 50 miles away in a surrounding county. For attorneys filing in Harris County courts and clients who need same-day access, proximity matters. No long drives. No waiting.
IAI publishes its prices — $250 standalone, $450 full PSI packet. No phone calls required just to learn what a test costs. Attorneys and clients deserve to know upfront. We are significantly below the Houston market average of $550–$1,600.
Dr. Walwyn is a former International Police Commissioner and U.S. territory Deputy Commissioner — not a retired patrol officer. His Ph.D. in Public Safety Leadership and active TCOLE Master Peace Officer License represent a credential level no competing Houston examiner can match.
IAI is a CJA Panel Vendor approved in three jurisdictions — the Southern District of Texas (federal), Harris County District Courts, and Fort Bend County Courts. Court-appointed defense attorneys can use IAI immediately, with zero additional authorization required.
VerifEye® remote assessment means your client never has to leave their home or county. Statewide access. No travel. Particularly valuable for defendants on bond conditions, clients in rural Texas, or attorneys managing time-sensitive matters.
IAI is a certified Minority Women-Owned Business with A.D. Walwyn as 51% Managing Member — a licensed private investigator with 12 years of Harris County Corrections experience and her own Certified EyeDetect® Examiner credential from Converus.
Your Examiner
Dr. Celvin G. Walwyn brings nearly four decades of law enforcement command experience to every assessment — from serving as Chief of Police in Texas to serving as International Police Commissioner for the Federation of St. Kitts and Nevis.
IAI is not a side business run by a retired patrol officer. Dr. Walwyn holds an active TCOLE Master Peace Officer License, a Ph.D. in Public Safety Leadership (Summa Cum Laude), and Certified EyeDetect® Examiner status from Converus — the world's leading credibility assessment technology company.
