PADI Divemaster Theory study plan

Map the Divemaster skill circuit into a written checklist of every demonstration-quality skill you must perform, and rate your current confidence on each from 1 to 5

Define the rescue sequence from recognition through exit in your own words, listing the decision points where a divemaster's role changes

Calculate and record your personal SAC rate from at least three logged dives using cylinder pressure, volume, and depth data

Explain the physics of buoyancy, pressure, and gas consumption aloud for ten minutes without notes, then flag every gap you hit

Work through the dive-planning tables to compute no-decompression limits, adjusted limits for repetitive dives, and surface intervals for five practice scenarios

Describe the signs, causes, and first-aid responses for the four most common pressure injuries and for oxygen toxicity

Draft a rescue scenario script with a buddy acting as a panicked diver at the surface, and run it twice

Explain the difference between an emergency action plan and an emergency assistance plan, and list what belongs in each

Draft a pre-dive briefing template covering site orientation, entry and exit, hazards, buddy procedures, and recall signals, then deliver it to a peer in under five minutes

Define the supervision responsibilities of a divemaster during a guided dive, distinguishing them from those of the instructor

Practice the rescue sequence in confined water or a pool, timing your response from recognition to control of the diver

List the common supervision failures that lead to dive accidents and match each to a preventive control

Build a supervision plan for a hypothetical guided dive with six certified divers of mixed experience, assigning buddy teams and recall points

Write out how you would handle three in-water problems: a diver low on gas, a diver who separates from the group, and a diver refusing to surface

Explain the role of the divemaster in conducting a dive site survey and in setting entry and exit procedures

Review the standards for supervising certified divers and list what a divemaster may and may not do without an instructor present

Map the sequence of a confined-water and an open-water training session, noting where the divemaster assists versus where the instructor leads

Practice demonstrating four skills on the skill circuit to demonstration quality, with a peer scoring each against the performance requirements

Describe how to set up a training area, brief students, and manage a student who is struggling with a skill

Explain the standards for student ratios, skill performance requirements, and the consequences of a skill being performed incorrectly

Draft a lesson-assist plan for one open-water skill, including positioning, signals, and how you would correct a common student error

Explain the divemaster's role in the Discover Scuba Diving experience and in the ReActivate program

Describe how to conduct a site assessment for a training dive, covering conditions, hazards, and suitability for student level

List the environmental practices a divemaster should model and enforce during training dives

Write a complete dive site map and orientation for a site you know, covering entry, exit, depths, hazards, marine life, and points of interest

Explain the roles of a divemaster in a dive site survey, in mooring and anchoring practice, and in managing diver traffic at a busy site

Describe at least six concrete conservation actions a divemaster can take and how to brief divers on them

Identify the local regulations and protected-species rules that apply at your most-dived site and summarize them in plain language

Run two full mock theory exams under timed conditions and review every wrong answer against the source material

Re-run the rescue scenario and two skill demonstrations, comparing performance against your week-one self-audit

Deliver a full pre-dive briefing and a conservation briefing back to back to a peer, and collect written feedback

Compile a one-page personal weak-point list with a specific corrective action for each item
