How to Choose an Open Water Instructor
Choosing the right Open Water instructor sets the foundation for safe, enjoyable diving. A skilled teacher helps you build solid habits and confidence, while a poor match can leave you stressed or undertrained. If you are in Chicagoland, consider one of our recommended private instructors. Private classes often cost more than shop courses, but the extra attention can pay off quickly.
Private instruction is not automatically better because the instructors are more skilled. Many shop instructors are excellent. The difference is usually logistics. Shops need larger classes to stay viable, which can limit individual attention, even when standards are met. Private instruction allows more flexibility and a tailored pace, which helps new divers progress faster.
Teaching Style & Personality
Every instructor has a distinct approach, and it can be hard to judge in advance. Use these signals to understand fit before you enroll:
- Ask former students about their experiences.
- Observe a class or a pool session if possible.
- Discuss their teaching philosophy and what success looks like.
- Notice how they answer questions and whether they stay engaged.
Instructor Communication Before Class
Clear, timely communication is a strong indicator of professionalism. Slow replies, vague answers, or disorganization are warning signs.
- How quickly do they respond to questions?
- Do they give direct answers and set expectations?
- Do they provide specific prep steps and schedules?
Experience & Qualifications
Look at both formal credentials and relevant experience:
- How long have they been teaching?
- Are they affiliated with a recognized training agency?
- Do they hold specialties such as technical training or human factors in diving?
- Have they trained divers in environments similar to your goals?
Class Size & Student Attention
Lower student to instructor ratios usually mean more feedback and time on task. Ask about roster limits and who will assist.
- What is the maximum class size?
- Will there be assistant instructors or divemasters helping?
- How much one on one time is typical during skills practice?
Diving Beyond Teaching
Instructors who dive for themselves bring current, real world context to class. If they are active outside courses, they often have sharper judgment about conditions, gear choices, and long term skill development.
Emphasis on Buoyancy & Trim
Buoyancy and trim should be threaded through the entire course, not isolated to a single session. Ask how they teach posture, breath control, and positioning, and how students practice these skills in open water.
Support When You Struggle
Progress varies by student. A good instructor has a plan for extra practice and clear policies for added sessions or fees if you need more time.
Local vs. Destination Checkouts
Doing pool and academics at home and checkouts on vacation can be convenient, but you will work with two instructors. Clarify handoffs, standards, and expectations so nothing falls through the cracks.
Safety & Standards
Look for consistent use of best practices: pre dive briefings, checklists, controlled skill progressions, and deliberate communication and situational awareness. Standards compliance is the baseline, not the finish line.
Equipment & Training Environment
Well maintained rental gear and appropriate training sites reduce friction for new divers. Ask about service intervals, fit options, and typical visibility and conditions at pool and open water locations.
Reviews & Reputation
Personal recommendations are still best. Ask trusted divers and local shops who they respect and why. Look for patterns in feedback rather than single opinions.
Costs & Hidden Fees
The cheapest class is not always the best value. Confirm what the fee includes, such as materials, gear rental, certification costs, site fees, and any charges for added pool or open water sessions.
Post Certification Support
Good instructors set you up for the next step. Do they suggest continuing education at the right time, connect you with clubs or buddies, and stay available for questions after the course?
