The Moment You Are Responsible for Other Divers, Everything Changes.
Divemaster is the first professional certification in SSI’s dive leadership pathway. It is the point at which you stop being a recreational diver and start being responsible for the experience, safety, and enjoyment of other people in the water. That shift in responsibility is not incremental: it is a different relationship with every dive you do.
Divemaster certification requires assessment, specific prerequisites, and a genuine readiness evaluation by Tom’s instructors. This is not something you sign up for the same way you sign up for a specialty course. Contact Tom’s to begin the conversation about whether you are ready and what the path looks like from where you are now.

The Assessment Is a Conversation About Where You Are and Where You Want to Go.
Call Tom’s. We will talk through your dive history, your prerequisites, and what a realistic path toward Divemaster looks like from where you are today.
CallWhat Readiness Looks Like for Divemaster
Divemaster is not the next course after Open Water. There is significant preparation required before the assessment conversation makes sense. Here is what Tom’s looks for:
Physics, physiology, and the science behind every dive.
SSI Science of Diving is a required prerequisite. It covers the knowledge base every dive professional needs: physics of diving, physiology, decompression theory, dive tables, and equipment science. You need this before DM enrollment.
Managing emergencies is the foundation of leadership.
SSI Diver Stress & Rescue is required. A Divemaster is the first point of professional response in an emergency. The rescue skills and stress recognition training from this course are not optional preparation: they are the baseline.
You have logged real dives in real conditions.
There is a minimum logged dive requirement for SSI Divemaster certification. More important than the number is the range: different sites, conditions, and situations. A DM candidate should have genuine dive experience, not just pool certification dives.
You are diving now, not just certified.
Divemaster training requires good in-water form. You should be diving regularly before you begin the program, not returning to the water for the first time in years. Your skills need to be current and solid.
The Skills and Responsibilities of a Dive Professional
Guiding certified diver groups
Planning, briefing, and leading certified diver groups in open water. Reading conditions, managing group dynamics, and maintaining awareness of every diver under your responsibility.
Emergency response as a professional
A Divemaster is the professional first responder on a dive. Rescue skills are practiced to a professional standard, including rescuing unconscious divers, managing panicked divers, and coordinating with surface support.
The science behind what you do
Physics, physiology, and equipment science at the level a professional needs. DM candidates complete written exams demonstrating mastery of the theory behind safe dive leadership.
Supporting SSI Open Water courses
Divemasters can act as a certified assistant for SSI instructors, supervising students during pool and open water training and taking up to two students on a no-skill excursion dive once the first two open water training dives are complete. A certified assistant supervises; they do not evaluate student skills. See what a certified assistant is for the full picture.
Demonstration-quality in-water performance
DM candidates must be able to demonstrate skills to a standard that models correct technique. This includes completing an extensive water skills circuit to a professional standard.
The standard that comes with a certification
Professional conduct, communication with students and clients, equipment management, and the judgment that being a dive professional requires every time you put your gear on.
Divemaster in the Lead / Pro Pathway
Divemaster, sometimes written dive master certification, is Step 1 of the SSI professional development pathway at Tom’s. It is both a standalone professional certification and the prerequisite for Assistant Instructor and Open Water Instructor.
Dive Guide
Non-professional leadership. Lead certified diver groups without professional compensation.
Divemaster
First professional certification. Lead certified divers commercially. Work with instructors on courses.
Asst. Instructor
Begin teaching under a certified instructor. ITC preparation begins here.
OW Instructor
Full teaching authority. Certify Open Water and continuing education students.

Professional development at Tom’s is not a product. The Divemasters who come through Tom’s are divers we have built a relationship with: people whose skills we know, whose judgment we trust, and whose development we take personal responsibility for. Over 400 five-star Google reviews and more than 18,000 certified divers reflect what we stand behind.
Forty-plus years of professional development.
Tom’s has been developing dive professionals since 1982. The DM program at Tom’s is not a new offering: it is part of a long-term investment in professional standards in Austin diving.
Globally recognized professional certification.
SSI Divemaster is recognized at dive operations worldwide. Tom’s is Austin’s only SSI Dive Center. The certification you earn here carries SSI’s full professional standing.
Train alongside a real teaching team.
DM candidates at Tom’s work alongside 30 or more active SSI-certified instructors. That is a fundamentally different professional development environment from a shop with one instructor running a DM program on the side.
No seasonal schedule interruptions.
DM training continues on a consistent schedule regardless of season. Our heated indoor pool means pool skill work never depends on Austin weather or outdoor pool availability.
We follow DAN dive safety protocols.
Tom’s follows Divers Alert Network (DAN) safety standards and recommends DAN dive accident insurance for every certified diver. Safety is not a checkbox on our website. It is the foundation of how Tom’s has operated since 1982.
Frequently Asked Questions
It depends on where you start and how frequently you train. With all prerequisites complete and consistent training, most candidates complete DM certification over several months. Realistic timelines are discussed during the assessment conversation. Rushing the program is not something Tom’s does: a DM certification from here reflects genuine capability.
Yes. Both are required prerequisites. Science of Diving and Diver Stress & Rescue must be completed before DM enrollment. If you have not taken them yet, that is the starting point of the conversation.
SSI Divemaster certification authorizes you to lead certified diver groups commercially and assist SSI instructors during courses. It does not authorize independent instruction. For full teaching authority, the next step is Assistant Instructor and ultimately Open Water Instructor.
SSI requires at least 60 logged open water dives for Divemaster. The quality of that experience matters as much as the count: different sites, conditions, and situations. If you are not sure whether your dive history is sufficient, calling is the right first step.
Becoming a Divemaster starts with completing the prerequisites, SSI Science of Diving, SSI Diver Stress & Rescue, and at least 60 logged dives, then scheduling an assessment conversation with Tom’s. From there, the Divemaster course combines knowledge development, in-water skills to a professional standard, and real-world leadership experience assisting SSI instructors. Call Tom’s to talk through where you are in that process.
