When I signed up for my Divemaster course. I didn’t feel like I was PADI® Divemaster material. I felt more confident about my diving skills after completing the PADI Rescue Diver class, but I didn’t see myself as a dive leader. 

For reasons I couldn’t fathom, my instructor insisted I would make a good Divemaster, despite the fact that:

  • What I knew about dive gear would fit on a yellow sticky note
  • To find my way back to the boat or shore I sometimes had to surface
  • My buoyancy was good, but nothing like the dive guides I’d seen

After serious nudging from my fellow Rescue Diver classmates, I decided to sign up. I’m so glad I did!

I incorrectly thought understanding how dive gear works and being able to lead a dive were prerequisites for starting the PADI Divemaster course. Not so! These are things you learn and master as part of your Divemaster training. Here’s what’s actually required.


PADI Divemaster Requirements

To start PADI Divemaster training you must be at least 18 years old* and have the following certifications:

You also need:

  • At least 40 logged dives 
  • Medical clearance to dive

*Divers who are younger than 18 but at least 15 and hold PADI Advanced Open Water Diver and PADI Rescue Diver certifications and have at least 20 logged dives may enroll in the PADI Junior Divemaster program. Junior Divemaster candidates complete a significant portion of the Divemaster course, but not all, and additional training is required when the Junior Divemaster turns 18 in order to become a Divemaster. 

There are also some important qualities every Divemaster should have that can’t be quantified. These are the things my instructor saw in me:

  • A commitment to protecting the environment
  • Strict adherence to safe diving practices
  • A caring nature and desire to help people

How to Prepare for the PADI Divemaster Course

A divemaster leads a line of divers underwater

Dive! Dive! Dive!

You need 40 dives to start the PADI Divemaster course and 60 dives to graduate. If you don’t have at least 40 dives yet, grab a tank and get going!  

While you’ll dive a lot as part of your Divemaster training, you won’t necessarily make 20 dives. 

Picking up a few specialty certifications is a good way to improve your skills while getting the dives you need.

  • Can you hover for a minute without finning or sculling? If not, take the Peak Performance Buoyancy specialty.
  • The PADI Deep Diver and/or PADI Search and Recovery specialty certifications are two others to consider because the divemaster course includes a deep diving and search and recovery diving workshop. If you have these certifications you can, at the instructor’s discretion, skip those workshops.

Assess Your Scuba Skills

Divemaster candidates should be comfortable performing all the basic scuba skills learned in Open Water. If it’s been a while since you did a mask removal and replacement or gear removal at the surface, put some time into improving any weak areas – especially buoyancy. You don’t want to be the Divemaster candidate who can’t hover. 

If it’s been a while since you took the Rescue Diver course, review those student materials as well. You’ll be expected to know how to respond to an unresponsive, non-breathing diver at the surface, among other skills. You’ll also need current (within the past 24 months) first aid and CPR training.

Find an Instructor

If you already have a favorite instructor, tell them you’re thinking about becoming a Divemaster. Some dive shops won’t offer a class until they have enough people who are interested

Medical Requirements

Before enrolling, make sure you meet the medical requirements for PADI Divemaster. In short, you must have been medically evaluated and cleared for diving by a physician within 12 months

Download the diver medical form and have it signed by a physician. The dive shop can’t accept a signature from a chiropractor, nurse, etc. If your doctor has questions or if you need assistance finding a physician, contact DAN (Divers Alert Network). DAN can connect you with someone in their worldwide network of physicians who serve the diving public.

How to Prepare for the Divemaster Swim Test 

The PADI Divemaster course includes three swimming assessments and one treading water exercise. *If you don’t currently spend a lot of time in the water (diving, surfing, swimming, etc.), build up your endurance before the course.  

*Accommodations can be made for Divemaster candidates with physical impairments.  

Here are the PADI Divemaster swim test (aka waterskills) requirements

  • Swim 400 meters/yards nonstop without swimming aids. Use any stroke or combination of strokes.
  • Swim 800 meters/yards face down – nonstop – using mask, snorkel and fins only. Use of arms or flotation aids is not permitted unless the candidate has a physical impairment.
  • Tow or push a diver for 100 meters/yards nonstop, at the surface, without assistance. Both divers wear full scuba equipment.
  • Wearing only a swimsuit, tread water, bob or float using no aids for 15 minutes. During the last two minutes, hold hands (not arms) out of the water. 

I’ve been a lap swimmer most of my life, so I didn’t practice holding my hands out of the water for two minutes. Much to my surprise, this last part of the treading water skill was a struggle. I completed it successfully thanks to a fellow Divemaster candidate named Keith. 

Earlier in this article, I mentioned there are qualities every Divemaster needs that are hard to quantify. Keith went on to be an exceptional Divemaster (and Instructor) because of his caring nature and desire to help people, including his fellow students!

Keith was missing one of his legs below the knee, but he was treading water and holding his hands up with the rest of us. Because of his physical impairment, Keith could have skipped the hand-raising challenge or the entire skill, but he didn’t. He hung in there, making jokes and encouraging everyone. Love and miss you, buddy.
