How Long Does It Take to Get Polygraph Results

The polygraph test is widely used in different professionals like law enforcement, federal jobs, and private investigative work to test people’s honesty. Knowing how widespread it is since people in many professions use it, a common concern for people undergoing a polygraph is the duration taken to receive results.

This article breaks down the polygraph process, factors influencing result timelines, and what to expect when undergoing such a test.

What is a Polygraph Test?

A “lie detector test,” or polygraph test, is a technique that assesses particular physiological metrics like heart rate, blood pressure, breathing rate, and skin conductance level. The purpose of the test is to identify changes that may indicate whether or not an individual is being truthful.

Despite its nickname, the polygraph doesn’t directly detect lies. Instead, it identifies physiological responses that could indicate stress or anxiety associated with deception.

Why Polygraphs are Used

Polygraph tests are widely utilized by:

• Government agencies for security clearances and job applications.
• Law enforcement for criminal investigations.
• Employers during pre-employment screenings in industries requiring high levels of trust.
• Lawyers and private investigators for legal disputes.

The goal is to validate an individual’s statements or clear doubts in specific circumstances.

How Polygraph Tests Work

During a polygraph examination, the subject is attached to the device via sensors. These sensors measure different physiological changes while the examiner asks a series of questions. Questions are typically categorized as follows:

• Relevant questions related to the purpose of the test.
• Control questions to establish a baseline physiological response.
• Neutral questions to calm the subject.

The examiner compares the physiological responses to determine if there are signs of deception.

The Steps of a Polygraph Examination

Here’s what the typical process looks like:

• Pre-Test Interview: The examiner explains the procedure and discusses the questions to be asked.
• Sensor Attachment: Sensors are attached to the subject’s body to monitor physiological changes.
• Test Execution: The examiner asks a set of questions while the subject responds.
• Data Analysis: The examiner reviews the recorded data to identify potential signs of deception.
• Post-Test Discussion: Some examiners discuss preliminary findings immediately after the test.

The time it takes to receive polygraph results can vary based on several factors:

• Immediate Results: For many private polygraph tests, immediate results may be provided right after the examination.
• Interim Reports: Government agencies may issue interim verbal results, often on the same day of the exam.
• Final Written Results: Receiving an official written report might take from a few days to weeks, especially if the results undergo a quality assurance review.

For non-government polygraph tests:

• Instant Results: Many private examiners provide results immediately after the completion of the test.
• Written Report: A written report may take a day or two to prepare and deliver to the client or person requesting the test.

How Long Does It Take to Get CBP Polygraph Results?

For CBP, the wait time for polygraph results can align with the complexity of the test and the follow-up reviews. Many have noted:

• Short Waits: Verbal feedback may be instant or within a day.
• Long Waits: Formal reports may take weeks or months, depending on the hiring process timelines.

Factors That Influence Polygraph Result Timelines

Several factors play a role in how quickly polygraph results can be shared:

• Nature of the Test: Screening tests for employment may take longer compared to case-specific investigations.
• Quality Assurance Reviews: Organizations often subject results to additional checks before releasing them.
• Volume of Tests: The time may extend during periods of high volume in government agencies or private firms.

Differences Between Instant and Delayed Results

The difference lies in:

• Instant results are processed by the examiner immediately after the test.
• Delayed results undergo additional reviews and audits, especially in official or legal cases.

Understanding Accuracy in Polygraph Testing

While modern polygraphs are highly advanced, they are not infallible. Accuracy depends on:

• The skills and experience of the examiner.
• The testing environment.
• The examinee’s mental and physical state.

Many polygraphs report accuracy rates between 85% and 90%, but no test is universally accepted as 100% reliable.

Preparing for a Polygraph Examination

These tips can help a subject prepare:

• Get adequate rest and eat a light meal before the test.
• Avoid excessive caffeine or stimulants that may affect physiological responses.
• Follow the examiner’s instructions carefully during the test.

What to Do After the Test

After completing the test:

• Wait for the official result or report without undue worry.
• If applying for a position, proceed with other steps in the hiring or application process.
• If you disagree with the results, discuss your concerns with the examiner or hiring agency if applicable.
