Polygraph Examiner
Characteristics of a Polygraphist
The Polygraphist is a people person who can at all times stay in control. He/she must
have a good memory, especially when it relates to conversations. They must be totally
ethical, honest, truthful and a moral person. Polygraphist deal with people’s lives and
livelihoods, therefore, must be reliable and have a certain measure of curiosity and
satisfaction in solving problems.
What is a Polygraph?
The term “polygraph” literally means “many writings.” The name refers to the manner in
which selected physiological activities are simultaneously recorded. Polygraph examiners
may use conventional instruments, referred to as analog instruments, or computerized
polygraph instruments.
It is important to understand what a polygraph examination entails. A polygraph
instrument will collect physiological data from at least three systems in the human body.
Convoluted rubber tubes that are placed over the examinee’s chest and abdominal area
will record respiratory activity. Two small metal plates, attached to the fingers, will record
sweat gland activity, and a blood pressure cuff, or similar device will record
cardiovascular activity.
The examinee is familiarized with test procedures and then questioned. The examiner
then analyzes a number of charts developed from the questions asked and renders an
opinion as to the truthfulness of the person taking the test.
Employment Opportunities
Polygraph exams are most widely used today by the law enforcement community. All federal law enforcement agencies either employ their own
polygraphist or use the services of examiners employed in other agencies. Staff examiners exist in the FBI, Secret Service, U.S. Army, Marines, Air
Force, Navy, U.S. Customs, Marshal’s Defense Criminal Investigation Service, Internal Revenue Service, Food & Drug Administration, and the
Department of Energy. In addition, U.S. intelligence agencies and Police departments use polygraph test in the pre-employment screening
process. In the private sector, attorneys use polygraph exams to help assist with their case or to strike a deal with the District Attorney. Private
Investigative companies use polygraph exams when disputes arise regarding the truthfulness of suspects in investigations.

Course Description
History & Development of the Detection & Deception through Scientific Means 8 Hrs
Ancient and recent methods of detecting deception are discussed. Emphasis is given to the development of instrumentation leading to current
methods for scientifically recording physiological changes associated with the psychological set of the person being examined. This includes a
discussion of the theory of “lie detection” the psychology involved; and the physiological changes recorded by the pneumograph, plethysmograph,
galvanograph and cardiophygmograph. Principles of test construction and limitations of the polygraph are discussed. All students are taught the
individual generally given credit for the development of each component of the polygraph and it being put together. The progression of the
instrument throughout its development up to and including the computer polygraph. This includes Stoeltring, Keeler, Lafayette, and others.
Mechanics of Instrument Operation 20 Hrs
Students are familiarized with functions of all components of contemporary polygraph instruments, including disassembly and assembly of each
instrument. Students are instructed in preventive maintenance, including identification, isolation and repair of malfunctions. Students will be
instructed in inspecting components for leakage, sensitivity, and methods of calibration. This includes dismantling, cleaning and the re-assembly of
Stoeltring and Lafayette instruments old and new.
Test Question Construction 25 Hrs
Students are taught question formulation of recognized techniques utilizing irrelevant, relevant, control questions, symptomatic, sacrifice relevant
and guilt complex questions.
Polygraph Techniques 40 Hrs
Students learn to properly attach polygraph components to the subject, and to sharpen their technical skills in overall polygraph instrumentation.
Students are familiarized with several recognized polygraph techniques with the main emphasis on the military MGQT and Military Zone of
Comparison Test. Each student is taught Peak of Tension Testing, both Known Solution and Searching Peaks and their use as investigation tools.
Test Data Analysis 30 Hrs
Chart markings used prior to, during and after administration of examinations are reviewed. Emphasis is given to reasons for, and the necessity of
standardized markings. The student receives extensive instruction in the recognition of physiological phenomena considered as deception criteria.
Using previous knowledge of criteria appropriate for rendering an opinion, the students are taught visual and numerical evaluations as appropriate
to making a determination of truth or deception.
Interviewing/Post-Test Procedures 14 Hrs
Students are taught the necessity of establishing proper rapport; the necessity of isolating the test issue from extraneous issues; the danger of
exhibiting a preconceived notion of guilt or innocence; the danger of giving the examinee a false sense of security due to examiner attitude; and the
necessity of maintaining total objectivity. Students will learn techniques of Post-Examination interviews and the importance of admissions following
the findings of deceptive criteria.
Ethics 6 Hrs
The students learn that the art of communicating with others is essential to a meaningful pre-test interview, test question formulation, and accurate
conclusions regarding test results. Each student is taught the necessity of maintaining confidentiality regarding interviews, attorney privileges and
the responsibility of accurate reporting that deals with people’s lives and livelihood.
Development of Student Skills 30 Hrs
Using previously gained knowledge; the student does extensive practical work formulating test questions for the various standard techniques. The
student works from previously prepared hypothetical test situations testing other students. This phase is conducted under close instructor
supervision and ongoing critiques. Everything the student has been taught regarding conducting the proper pre-test interviewing, question
formulating, placing the attachments on the subject, running stim tests, proper chart markings, numerical evaluation and post-test interviews are
developed. This block of instruction prepares the student for a meaningful apprenticeship in real life polygraph.
At the Discretion of the Director
20 Hrs
Any areas of the curriculum that needs additional reviewing or instruction is at the discretion of the Director will be utilized.
Legal Issues 8 Hrs
Acquaints the student with the rules of admissibility. Familiarizes the student with legal restrictions and limitations on use of the polygraph.
Particular emphasis is presented on conditions of commercial use of the polygraph. Students are taught court proceedings, including types of
examination and cross-examination to be expected when being qualified and subsequently testifying as an expert witness. Mock courtroom
situations are observed, (Video tape) and discussed to prepare students for courtroom testimony or presenting their work to the District Attorney or
other polygraph examiners. Basic courtroom terminology and procedures are also included.
Psychological & Physiological Issues 25 Hrs
Students are introduced to general psychology as it pertains to normal behavior. They are presented with a study of human personality
differences and deviations. Encourages research and study of personality and psycho-physiological differentials and the affect on polygraph
results. Students study the function of cells, tissues, glands, major organs and systems of the human body. They study the nervous system,
cardiovascular system and the respiratory system, with emphasis on their roles and implications in polygraph.
Student Performance Evaluation 14 Hrs
Weekly examinations are administered to evaluate student progress, and to identify their strengths and weaknesses in absorbing the instructional
material. Students are given the opportunity to critique the course material, the instructors, and the quality of instruction.
Post-Graduate Internship for Polygraph Examiner Certification 60 Hrs
Upon successful completion of the Polygraph Examiner’s training of 240-classroom hours, each student is issued a Certificate of Completion, for
the academic course. Prior to being awarded the American College of Forensic Studies Certification Diploma, the student must submit 20-
polygraph examinations that must demonstrate proficiency, competency and proper application of the principles and techniques taught at the
college. The examinations must be submitted to the college to be given credit for the additional 2-week field project. The 20-specific examinations
