Education and Examination Guidelines for Iridology Syllabus and Exam Procedures

Part One: Guidelines for Course Curriculum


  1. Students must hold:
    • a recognised certificate in Anatomy and physiology and should be currently using the knowledge. A student that has not practiced since their exam may need a refresher course. This is at the discretion of the Tutors
    • a recognised qualification in a complementary medicine discipline as accepted by the Exam Board, e.g. homeopathy, herbal medicine, osteopathy, chiropractic, acupuncture
  2. Tutors must have been in active practice for at least five years. They may be asked to produce evidence and attend an interview with the Exam Board.

Contact Teaching Hours (time when students are with tutors, being taught):

  1. A minimum of seventy two (72) hours is required. This can include the hours allotted for clinical training but must include a minimum of 42 hours contact time. Students of Iridology who are already qualified in one or more therapies and who can demonstrate sufficient clinical experience, both as part of their training for previous qualifications and from their own practice, may, at the discretion of the course principal be eligible for an appropriate reduction in the number of clinical training hours
  2. The minimum range of time for the training is to be not less than nine (9) months. Colleges may schedule tutorial and other work according to their own discretion within this time.


  1. Tutors are to keep an attendance record. This is to be made available to the Examiner, who can take it away if desired.
  2. Student attendance at course meetings must be full. Students must make up any missed time and arrange this with the Tutor. (Tutors may arrange make-up days for several students at a time and include extra assignments to reach contact hour requirements.)
  3. Absences and content of material missed is to be noted to the Exam Board.

Case Histories:

  1. The curriculum must include the taking and monitoring of ten (10) case histories. Five (5) of these are to be done under tutor’s supervision.
  2. Case histories are in the form of a written report on the initial findings:
    • the analysis
    • the interpretation of significant signs
    • any referrals and/or recommendations as may be suggested by the analysis
    • at follow-up consultations, any changes and recommendations are recorded

    Reports should be written in essay form and demonstrate the student’s understanding of record-keeping understandable to fellow practitioners who may be required to take over the case.

  3. These case histories will form part of the work presented to the Examiner on the day of the Guild Exam and can be taken away by the Examiner. A candidate’s exam paper will not be marked unless the case histories are completed by the candidate.

NOTE: Colleges will provide the Education Committee with a copy of the timetable for teaching the curriculum, i.e. a guide to when each topic will be taught. Changes to this should be notified to the Education Committee.

Part Two: Anatomy & Physiology

All exam candidates must have already a recognised A&P qualification. This training can be inclusive within the Iridology course and taken at the same time. It can be external training or have been taken as part of training for osteopathy, chiropractic, homeopathy, herbalism, acupuncture, medical practice, etc.

    3. Course work should include learning about other complementary therapies.
    4. Reinforcement of holistic A&P is to be integrated with Iridology training.

Part Five: Examinations

Note: The aim of the Guild Examination is to assess basic competence in Iris Analysis theory and professionalism communicating this to the patient/client in the clinical setting. Colleges are free and encouraged to set their own internal exam covering the particular concepts they have taught.

Exam Questions
These will be taken from the textbooks or course material submitted by the colleges as reflected in the question bank. Colleges are to submit questions for the question bank but bearing in mind that questions are not solely for their own students.
Colleges are to submit an example answer to each question indicating the accepted answer.
Each school may work from its own chart as long as this chart is supplied to the examiner when the exam is booked.
A bank of questions will be maintained by the Exam office and randomised for use on the exam papers, repeats kept to a minimum.


  1. Invigilation of both theory and practical will be conducted by a member of the Exam Committee.
  2. Venue: Several venues will be available and colleges will be notified of the available dates. Exams can be held at a college for a minimum of ten (10) students.
  3. Booking: Booking for the exam is to be made at the beginning of the course.
  4. Fees: The fee for the exam is £100.00 per student. This covers the office running costs (postage, printing, etc.) and the examiner’s fee, but not his or her expenses. Expenses are to be offered to the examiner by the college and contracted individually.
    The fee is payable three (3) months prior to the exam date. Fees are not refundable but may be transferred to another date providing that is within twelve (12) months of a cancellation. If a student delays the exams beyond this point, tutors may require additional tuition as they feel necessary.

Examination Procedure:
The Exam office will send the required number of papers to the examiner two weeks/14 days before the exam along with a list of candidates’ names and directions to the venue.

  1. Theory: The theory paper will consist of 2½ hours of questions based on the recommended course books. Included is a question asking for a full report on an iris analysis – interpretation based on a photograph of a subject’s eyes (both eyes). Photos will be provided for each student by the Examiner.
    The theory paper will be brought in by the examiner and opened in front of the students. The papers will be handed out face down and students started at the same time. At the end of the exam all answer papers and exam papers will be taken away by the examiner for marking. Answer papers will be marked with percentage and the results sent to the Guild Head Office, who will notify the Colleges of the individual results and provide endorsements accordingly for the relevant diplomas.
    A half-hour extra will be allowed for candidates whose first language is not English or for candidates with learning difficulties if the Examiner is notified of this prior to the exam date. Any student arriving late will not be allowed to take the Exam. Once the exam has started, candidates will not be allowed to leave the room until all others have finished, except in extreme emergencies.
  2. Practical: A 15 minute examination on the candidate’s professionalism, e.g. appearance, record keeping, communication skills in interpreting the iris information for the patient/client, making appropriate referrals and/or recommendations.
    Colleges are required to provide patients for the practical exam if this is held in the locality of the college.


    • The pass mark for the theory is 70%
    • The practical will be graded, C being the lowest mark.

    Candidates must pass both sections to be eligible for the Guild diploma. If one part is failed, a retake can be arranged again on payment of half the exam fee.

  3. Arranging for the exam: Booking of the exam should be done at the beginning of the course, i.e. at least nine (9) months in advance. Booking fee is paid three (3) months prior to the exam date.
  4. Results: In the event of College Directors requesting copies of test results of further assessment, photocopies can be provided at a minimal cost.
  5. Colleges are asked to send in copies of graduates’ certificates, both new and previous graduates, to the Exam office to establish the standard of Iridology graduates.

Part Six: Inspections and Tutor assessment

  1. Colleges will be inspected every two years for suitability for delivering the curriculum. This does not take the place of the legal requirements for college venues already existing.
  2. If the venue is changed, the new one will be inspected. A Certificate will be issued and the College will be put on the list of accredited colleges.
  3. At some point in the course, the Education Committee will observe and assess the tutor teaching the curriculum. This will be a one-off for each tutor.
  4. Colleges will notify the Education Committee of any change in tutors.
  5. The fee for the inspection and assessment will be £100.00 plus expenses. The two, inspection and assessment, can be done together
