PADI IDC & IE preparation guide
How to Prepare for Your PADI IDC and Instructor Examination
Use this practical, stage-by-stage plan to arrive theory-ready, make every day of your Instructor Development Course count, perform calmly at the PADI IE and begin your career as a PADI Open Water Scuba Instructor.
18 yearsof PADI Course Director experience
Four stagesbefore, during, IE day and first 90 days
Fact-checked
The right objective
Prepare to become a capable Instructor, not merely to survive an examination
The PADI Instructor Development Course develops your ability to teach using the PADI System. The Instructor Examination is an independent PADI evaluation of whether you can demonstrate the required knowledge, skills, teaching ability, control and professional judgement. Exam preparation matters, but the real goal is to become the Instructor whom students and employers can rely on.
PADI can update standards, assessments, authorised materials and remediation rules. Your current Instructor Manual, Guide to Teaching, Training Bulletins or Training News, candidate materials, Course Director instructions and IE orientation always take precedence over this webpage.
Understand the journey
The pathway from Divemaster to PADI Open Water Scuba Instructor
The IDC and IE are separate stages. Completing the IDC prepares you to attend the IE; passing the IE is followed by PADI application processing and confirmation of your professional status.
Confirm eligibility
Verify your professional rating, certification history, logged dives, first-aid currency, medical, EFR Instructor plan and documents.
Complete the IDC
Develop knowledge presentations, confined- and open-water teaching, demonstration-quality skills, student control and standards knowledge.
Attend the PADI IE
A PADI Examiner independently evaluates the required written, teaching, in-water, rescue and professional-performance areas.
Begin teaching responsibly
Wait for confirmation of your rating and teaching status, meet insurance and local requirements, then build experience with good mentoring.

| Readiness area | What preparation should produce | Strong evidence of readiness |
|---|---|---|
| Written knowledge | Dive theory plus accurate use of current PADI Standards and Procedures. | Strong results in every topic on unfamiliar, timed work. |
| Knowledge development | Clear, relevant teaching that answers the assignment and helps a diver apply it. | You can prepare an unfamiliar topic without a memorised script. |
| Confined water | Effective briefing, organisation, demonstration, observation, correction and debriefing. | You maintain control while detecting and correcting student problems. |
| Open water | Safe site organisation, appropriate assistant use, student control and effective teaching. | Your plan remains clear when conditions and logistics add pressure. |
| Skills and rescue | Demonstration-quality dive skills and an organised, effective rescue performance. | Performance stays repeatable in the equipment and environment used at the IE. |
| Professionalism | Preparedness, safety awareness, communication, judgement and constructive response to feedback. | You remain calm, coachable and focused on the assigned requirement. |
The actual sequence, assignments, scoring and remediation arrangements may change. Confirm them through your current candidate materials and IE orientation. See the official PADI Instructor Examination calendar for current regional schedules.
For prospective candidates
Choose an IDC that will prepare you properly
A short timetable or low headline price does not tell you whether a program will identify weaknesses early, give you enough realistic practice or help you begin teaching after the examination.
Preparation
- When does theory assessment begin?
- What help is available if a weak area is found?
- Does preparation include unfamiliar, timed questions?
- How much work must be completed before the first day?
Teaching practice
- How often will you deliver each type of presentation?
- Will you practise recognising assigned student problems?
- Are realistic mock-IE assignments included?
- Who provides individual feedback and remediation?
Complete cost and timetable
- Which materials, applications and PADI fees are additional?
- Is EFR Instructor training included?
- Are medical, equipment, insurance and travel separate?
- Are the IDC and IE dates both confirmed before you book travel?
After the IE
- Can you observe or team-teach with experienced Instructors?
- Is practical employment guidance included?
- Will someone review your first courses with you?
- Are job claims realistic and free from guarantees?

The complete preparation priorities
10 practical actions to strengthen your PADI IE readiness
- Master dive theory before the IDCUse the IDC to learn teaching, not to rebuild Divemaster knowledge.
- Keep a theory mistake logRepair the reason for each error, then retest with different questions.
- Learn to locate current StandardsKnow where and how to verify an answer instead of relying on memory.
- Complete two realistic mock IEsUse unfamiliar assignments, current criteria, time pressure and no coaching.
- Use repeatable teaching structuresClear organisation frees your attention for students and safety.
- Make demonstrations unmistakableBe slow, accurate, visible, neutrally buoyant where appropriate and consistent.
- Recognise and correct student problemsTeaching is observation, intervention and reassessment—not just demonstrating.
- Make rescue performance automaticPractise the complete performance in realistic equipment and conditions.
- Assist with real beginner coursesLearn how real students behave from a patient, standards-focused Instructor.
- Remove avoidable IE-day problemsControl paperwork, equipment, travel, sleep, food and your response to pressure.
Before and during your course
An adaptable eight-week IDC-to-IE roadmap
Map these stages to the schedule supplied by your Course Director. Start earlier if your theory is rusty, your rescue performance is inconsistent or you have not recently assisted with entry-level training. Complete teaching rehearsals and mock evaluations only after your Course Director has introduced the current methods and criteria. The aim is progressive mastery, not one lucky practice result.
Verify eligibility, finish pre-study and diagnose your starting point
Ask your Course Director to check documents, then complete every assigned eLearning module, knowledge review, workbook task and other pre-study by the stated deadline. Use authorised unfamiliar theory practice, a skills review and a supervised full rescue performance to identify gaps without trying to hide them.
Ready to move on when: every assigned task is complete and every gap has a named action and deadline.
Repair dive-theory weaknesses
Prioritise the two weakest topics. Use authorised learning materials, a mistake log, spaced retesting and explanations spoken aloud in simple diver language.
Ready to move on when: strong results repeat on different questions.
Build a reliable Standards navigation system
Use the current Instructor Manual, Guide to Teaching and updates confirmed by your Course Director. Practise locating requirements, conditions and exceptions under time pressure.
Ready to move on when: you can support answers from the current source rather than guessing.
Film demonstrations and refine buoyancy
Practise every skill on the current evaluation list in the equipment and exposure protection you expect to use. Review pace, sequence, visibility, trim and student-control position.
Ready to move on when: quality is repeatable, not dependent on a perfect first attempt.
Practise unfamiliar presentations and student errors
After your Course Director introduces the current teaching methods and criteria, use one structure for knowledge development and one for in-water teaching. Rotate assignments, student roles and problems so you learn to think instead of reciting.
Ready to move on when: you can teach, observe and correct without prompts.
Complete the first full mock IE
Under your Course Director’s direction, use original unfamiliar theory practice, standards work, teaching assignments, skills and rescue. No coaching once an exercise begins. Convert every result into a specific remediation task.
Ready to move on when: all high-risk safety, standards and control issues are corrected.
Prove consistency, then reduce the load
Complete a second independent mock on another occasion. Confirm equipment and logistics. Use the final days for brief recall and confidence-building rather than exhausted late-night cramming.
Ready for the IDC or IE when: you perform reliably without help and arrive rested.
Do not divide limited time equally across every topic. Ask your Course Director to identify weaknesses most likely to affect safety or successful completion, then address them in that order. Begin with eligibility, theory diagnosis, rescue and student control.
Priority one
Arrive with dive theory already learned
A future Instructor must do more than recognise the correct multiple-choice answer. You need to understand the principle, apply it to a dive and explain it clearly to a student.
Physics
Pressure, volume, density, buoyancy, gas behaviour, partial pressure, light, sound and heat.
Physiology
How pressure, gases, temperature, exertion and stress affect divers, including prevention and response.
Equipment
How major scuba components function, how configurations affect performance and why problems occur.
Skills and environment
The principles behind core skills and how conditions affect planning, teaching and supervision.
Decompression and planning
Nitrogen loading, dive profiles and use of the current planning tools required by your training materials.
The six-step repair method
- Complete an unfamiliar, timed set of questions.
- Mark every wrong answer and every answer you guessed.
- Identify the precise misconception, missed word, unit or calculation step.
- Return to the authorised source and rebuild the reasoning.
- Explain the concept aloud without seeing answer choices.
- Retest with a different question after one day, three days and one week.
A focused 45-minute study session
- 10 minutes: recall key ideas without notes.
- 15 minutes: repair one weak concept.
- 15 minutes: answer unfamiliar application or calculation questions.
- 5 minutes: update the mistake log and schedule the next retest.
On a phone, swipe or scroll horizontally to view all columns.
| Topic | Error or uncertainty | Why it happened | Correct principle or source | Retest |
|---|---|---|---|---|
| Physics | Pressure calculation | Used gauge pressure instead of absolute pressure. | Write the known values and units before selecting the relationship. | Different question in 24 hours. |
| Physiology | Two answers seemed possible | Missed the words “most likely” in the question. | Underline the qualifier, then explain why the alternatives are weaker. | Mixed set in three days. |
Use the complete Abyss dive-theory study guide
Review the five theory areas, essential relationships, error-log method and a detailed four-week study program.
PADI’s current Dive Theory eLearning covers physics, physiology, equipment, decompression theory and dive planning. PADI says IDC candidates may earn exam credit and should ask their Instructor for details. Credit, when confirmed, does not replace the ability to understand and teach the material. Review PADI Dive Theory eLearning.
Know where to verify
Build fast, accurate PADI Standards navigation
Memorised numbers can become outdated, can belong to the wrong program or can omit an important condition. A professional Instructor knows when and where to verify a requirement.
Practise these lookup categories
- Entry prerequisites and minimum ages
- Ratios and supervision requirements
- Depth limits and environmental conditions
- Required sequence and performance requirements
- Forms, referrals, credit and documentation
- Course-specific exceptions and professional judgement
Use a four-part lookup drill
- Find: locate the controlling section in the current authorised material.
- Read: check the surrounding conditions, notes and exceptions.
- Answer: respond to the exact scenario in plain language.
- Cite: record where you found it so your Course Director can verify your interpretation.
Standards lookup laboratory
Ask a Course Director or study partner to give you scenarios without supplying the topic heading. Use only the materials confirmed as authorised for your current program.
On a phone, swipe or scroll horizontally to view all columns.
| Scenario type | Where found | Answer in my own words | Conditions or exceptions | Verified? |
|---|---|---|---|---|
| Minimum age | Current source and section | Concise answer | Supervision or depth conditions | Course Director check |
| Referral or credit | Current source and section | Concise answer | Time, paperwork or sequence conditions | Course Director check |
Sign in to the current PADI Pros environment and use the version, errata and training updates specified by your Course Director. Internet summaries and another candidate’s notes are not controlling standards.
Teaching under pressure
Use simple structures that leave attention for your students
Do not memorise a theatrical script. Use the current PADI evaluation criteria as your checklist, then explain naturally and stay focused on the assigned learning outcome.
Knowledge development
Connect → Objective → Explain → Apply → Check → Close
- Connect the topic to a realistic diving situation.
- State what the learner needs to understand or do.
- Explain the assigned point accurately and at the right level.
- Apply it to safer, easier or more enjoyable diving.
- Check understanding with a meaningful question.
- Close with the central point and next step.
In-water teaching
Brief → Organise → Demonstrate → Observe → Coach → Confirm → Debrief
- Explain the objective, value, key steps, signals and likely problems.
- Position students and assistants so you can maintain control.
- Give a slow, correct, visible demonstration when required.
- Watch every student rather than watching your own performance.
- Recognise and correct problems safely and clearly.
- Have the student repeat the skill and confirm mastery.
- Debrief specifically, positively and accurately.
Your job is to create the conditions in which students can understand it, attempt it safely, receive useful correction and demonstrate mastery.
Knowledge presentation check
- Did I answer the assigned question directly?
- Was every explanation accurate and relevant?
- Did the application help a diver make a better decision?
- Did I confirm learning rather than ask “Understand?”
Confined-water check
- Could every student see and understand the demonstration?
- Was my position effective for observation and control?
- Did I recognise, correct and reassess the problem?
- Was the debrief specific to actual performance?
Open-water check
- Did the site plan support safe, efficient teaching?
- Did I give the assistant a useful, specific role?
- Did I maintain awareness beyond the student performing?
- Did I adapt calmly without abandoning the assignment?
In-water performance
Demonstration skills, student control and rescue readiness
Make demonstrations easy to copy
Perform the current required skills slowly, in the correct sequence and with critical actions clearly visible. Maintain appropriate buoyancy and trim, but never become so focused on appearance that you stop watching students.
Ready when: you can reproduce the same quality in the exposure protection and equipment expected at the IE.
Practise seeing the whole group
Choose a position that gives you clear sight lines and access. Deliberately rotate simulated errors. Signal the correction, have the student repeat the skill and verify that the problem is resolved.
Ready when: you detect the problem promptly without losing awareness of everyone else.
Make the complete rescue automatic
Practise the full performance with an appropriately qualified professional: organisation, personal safety, effective rescue breathing, towing, equipment management, continued care, exit coordination and communication.
Ready when: your performance remains organised under observation in realistic equipment and professionally supervised conditions.
Have an appropriately qualified observer film a skills circuit
Keep your attention on divers, control and the assigned performance while the observer manages the camera. Review the recording together afterwards.
- Is the sequence correct?
- Can students see the critical action?
- Is the pace deliberately slow?
- Are signals and pauses unmistakable?
- Is buoyancy appropriate to the skill?
- Does the position maintain control?
- Do you keep observing the group?
- Can you repeat it without coaching?
Safety note: Rescue and in-water practice must be supervised appropriately. Do not practise alone or continue to unsafe exhaustion. Follow the current performance and evaluation requirements supplied for your IDC and IE.
Prove readiness
A useful mock IE must test performance, not memory
Repeating a familiar rehearsal proves that you remember the rehearsal. Performing well with an unfamiliar assignment shows that your knowledge and teaching process transfer under pressure.
Your mock should include
- Original unfamiliar practice questions based on current learning objectives
- Standards scenarios using current authorised materials
- An unfamiliar knowledge-development assignment
- Confined- and open-water teaching assignments
- Student-problem recognition, correction and reassessment
- Demonstration-quality skills and rescue assessment
- Realistic equipment, exposure protection and logistics
Conditions that make it meaningful
- Current evaluation criteria supplied by the Course Director
- The relevant preparation and time conditions
- No coaching after an exercise begins
- Specific written feedback immediately afterwards
- A remediation task for every weakness
- A second full mock on another day with new assignments
A sensible Abyss readiness gate
Attend the IE when you can pass every component comfortably on more than one occasion. A strong total should never disguise one unreliable theory topic, unsafe control habit or rescue weakness.
During your IDC
Turn every piece of feedback into one observable change
The IDC becomes overwhelming when candidates collect comments without converting them into behaviours they can rehearse. Use the same short feedback loop after every assessment.
- 1
Record the observation
Write what the evaluator actually saw or heard, not your intention.
- 2
Set the priority
Must fix: safety, standards or control. Should fix: clarity, sequence or problem recognition. Polish later: style.
- 3
Name one behaviour
Convert “improve control” into something observable, such as changing position so every student remains visible.
- 4
Rehearse it the same day
Use a short, focused repetition while the feedback is still clear.
- 5
Test it on a new assignment
Ask whether the change solved the original problem without creating another.
- 6
Protect sleep
Stop when fatigue is lowering the quality of study. Consolidation is more valuable than late-night panic.
On a phone, swipe or scroll horizontally to view all columns.
| Assignment | What was observed | Priority | Behaviour to change | Retest evidence |
|---|---|---|---|---|
| Confined water | Looked at one student for too long. | Must fix: control | Scan both students after every signal. | New assignment completed with continuous awareness. |
| Knowledge | Accurate but too much background detail. | Should fix: clarity | Answer assigned point first; use one application. | Next presentation finished clearly and on topic. |
Ask useful questions
Ask “What did you observe that lowered this performance?” and “What one change should I demonstrate next time?” These produce clearer action than asking only how to gain more points.
Assist real courses
When permitted, assist a patient, standards-focused Instructor. Observe the timing, misunderstandings, stress responses and buoyancy problems that genuine beginners bring.
Use your candidate team well
Rotate student roles and realistic problems. Give specific feedback, but never teach another candidate shortcuts that conflict with the Course Director’s guidance.
IE week
The final 48 hours and PADI IE day
Your last two days should reduce uncertainty. They are not the time to rebuild theory, change your teaching structure or learn unfamiliar equipment.
Documents and materials
- Identification and all candidate paperwork
- Certification evidence and accurate logbook
- Current physician-signed medical and first-aid evidence
- Authorised reference materials confirmed by your Course Director
- Stationery, slates and teaching aids requested for the program
Equipment and logistics
- Familiar, serviced and complete dive equipment
- Correct weighting for the venue and exposure protection
- Sensible spares such as straps and a mouthpiece
- Confirmed start time, meeting point, transport and parking
- Food, water and protection from the expected weather
Personal preparation

Common questions
PADI IDC and Instructor Examination FAQs
What does PADI IDC stand for?
IDC stands for Instructor Development Course. PADI describes the IDC as comprising the Assistant Instructor course and the Open Water Scuba Instructor program. Most candidates complete the full IDC before attending the Instructor Examination.
What is the difference between the IDC and the PADI IE?
The IDC is the training and development program conducted by a PADI Course Director. The PADI Instructor Examination is the separate, standardised evaluation conducted by a PADI Examiner. Completing the IDC does not by itself make someone a PADI Instructor.
What are the current entry requirements for a PADI IDC?
Current public PADI information includes being at least 18, holding PADI Divemaster or a qualifying professional rating, being a certified diver for at least six months, having at least 60 logged dives to begin, current qualifying CPR and first aid, and the required physician-signed medical. You need 100 logged dives to attend the IE. EFR Instructor is also required for PADI Instructor certification and may be completed during instructor training. Have a Course Director verify that every document—including the exact medical form—will remain acceptable for your actual IDC and IE dates. Report any health change and obtain updated clearance whenever directed.
How early should I begin preparing?
Six to eight weeks is a useful minimum for a candidate whose Divemaster knowledge and skills are reasonably current. Start earlier if your theory is rusty, you have not recently assisted with students, or rescue and demonstration skills need rebuilding.
Which dive-theory subjects should I revise?
Prepare across physics, physiology, equipment, skills and environmental considerations, and decompression theory and dive planning. Use the subject divisions and tools in your current PADI materials because terminology and assessment arrangements may change.
What score should I aim for in PADI IE theory preparation?
Abyss recommends consistently reaching 85–90% or better in every topic on unfamiliar practice work. This is a preparation benchmark designed to create a safety margin and expose weak topics—not an official PADI pass score. Confirm current official performance requirements with your Course Director and at the IE orientation.
Do I need to memorise all PADI Standards?
No Instructor can safely depend on memory for every requirement and exception. Learn the central principles, then become efficient at locating and interpreting the controlling information in current authorised materials. Confirm which materials may be used in each current assessment.
What does the PADI IE assess?
PADI publicly describes the IE as evaluating teaching ability, dive-theory knowledge, skill level, understanding of the PADI System, attitude and professionalism. Candidates should prepare for written knowledge, knowledge-development teaching, confined- and open-water teaching, demonstration-quality skills and rescue. The exact order and assignments can vary.
Can a dive professional from another training organisation enter the OWSI program?
PADI states that some Instructors from other diver-training organisations may be eligible to enrol directly in the OWSI program. Equivalency is not automatic, so send your complete credentials and experience to a PADI Course Director for verification.
What if one IE assessment does not go well?
Stay focused on the next task and listen closely to the Examiner. Current reassessment or remediation rules, timing and fees must come from the Examiner and current candidate information. Do not plan around retest descriptions found in old webpages.
Can I teach immediately after hearing that I passed?
Do not represent yourself as authorised to teach until PADI has processed and confirmed your certification and teaching status. You must also meet professional insurance, employment, visa and local legal requirements that apply where you intend to work.
Does this guide guarantee that I will pass the PADI IE?
No. It is a preparation framework designed to remove preventable weaknesses and help you use your IDC effectively. Your performance, eligibility and the current PADI evaluation requirements determine the outcome.
