Post-Conviction S*x Offender Testing (PCSOT)

At Kieso Polygraph Services, we provide certified Post-Conviction S*x Offender Testing (PCSOT), a vital tool designed to support community supervision, enhance public safety, and assess compliance within therapeutic treatment programs.

PCSOT is a highly regulated, evidence-based polygraph process requiring advanced training and adherence to strict standards set by the American Polygraph Association (APA). Working in close collaboration with probation officers, parole agents, and treatment providers, PCSOT testing acts as a tool for detection, deterrence, and disclosure of compliance with community supervision and treatment conditions.

Core Components of PCSOT

• S*xual History Disclosure Exams: Designed to uncover comprehensive historical context, to encourage truthful disclosure of evidence based high-risk behaviors prior to conviction.

• Instant Offense & Denial Testing: Used to address instances where an offender minimizes or denies the details of his or her conviction relative to official court and investigative records.

• Monitor Testing: Screening examinations specifically administered to assess that the individual has not committed any new or undisclosed sexual offenses while under supervision.

• Maintenance Testing: Periodic screening examinations used to thoroughly investigate compliance with court-mandated probation rules, parole conditions, and treatment terms (e.g., contact with minors, curfew, restricted contacts, viewing forbidden materials, etc.)

• APA-Approved Certification: Christian holds specialized, advanced credentials specifically required for post-conviction testing.

• The Community Supervision Team Approach: We act in collaboration alongside the supervising officer and treatment provider to manage offender risk effectively.

• Proven Containment Model Alignment: Our testing protocols are meticulously designed to fulfill the communication, transparency, and risk-reduction goals of the gold-standard Containment Model framework.

• Fast, Professional Reporting: We deliver clear, detailed forensic and clinical assessments to assist probation/parole and treatment providers in timely case decision-making.

We work directly with courts, treatment programs, and supervising agencies.

Did you know?

A polygraph examination or (PDD) is often incorrectly referred to as a "lie detector test."

- The correct scientific and legal term is a polygraph examination or psychophysiological detection of deception (PDD) examination.

A skilled and competent polygraph examiner must have strong critical thinking skills.

- Critical thinking is the clear, active process of analyzing, questioning, and evaluating information rather than accepting it at face value.

- It uses logic and evidence to solve problems, spot hidden biases, and make smart choices about what to believe or do.

Key Steps to Analyze:
- Break down information into smaller parts.
- Question: Check where facts come from and find hidden assumptions.
- Evaluate: Weigh different proofs and view things from multiple sides.
- Reflect: Look at your own biases and change your mind if facts change.

Why It Matters:
- Helps you solve hard problems.
- Protects you from fake news and bad ads.
- Leads to better choices in daily life.

Did You Know?

Many people are surprised to learn that the majority of a professional polygraph examination takes place before any sensors are attached (not like what you see on television).

The pre-test interview is one of the most important parts of the examination. During this phase, the examiner:

• Learns the details of the issue(s) being investigated
• Reviews the allegation(s), or screening issues that will be addressed
• Clarifies facts and timelines
• Develops precise, relevant test questions, and the examinee will know exactly what's going to be asked. There are no surprise or trick questions.
• Ensures every question can be answered with a simple "Yes" or "No"

This preparation helps produce a fair, understandable, and reliable examination.

A quality polygraph examination begins long before the charts start recording.

Professional. Confidential. Accurate.
