Frequently Asked Questions

How long does it take to complete MSDT Prep and an Internship?

The Master Scuba Diver Trainer (MSDT) program is broken into two separate sections that can be done together or separate.

The first section is conducted over a 5/6-day period and focuses on Specialty Instructor Training.

In the first part we break down the Instructor Specialty outlines and review the standards in order to teach the course.

This covers all knowledge development, water work and promotional techniques.

The second part focuses on gaining real life teaching experience. You assist members of our Senior instructor team in teaching a range of PADI Courses.

How do I get real life teaching experience as an MSDT?

During your MSDT internship you will be assisting some of our experienced instructors, teaching real life entry level courses.

We conduct the full range of courses within the PADI system. This gives you lots of opportunity to work with a diverse group of students and seasoned instructors.

We encourage you to get involved with numerous types of courses from the PADI Open Water Diver Course to the PADI Rescue Diver Course.

Additionally, you can choose to get involved in our Pro-level training and take part in Divemaster Workshops. This allows you to gain teaching experience in a diverse range of PADI courses.

Can I choose what Dive Instructor specialties to take?

We offer a wide range of instructor specialty training and we allow you to choose from our available options.

Your Course Director can help to guide you through this process and help you to choose the right specialties.

Certain specialties require additional prerequisites. For example; the Enriched Air Diver Instructor course requires you to have the student level certification.

If you do not hold this particular specialty diver level certification, you take the diver level course in conjunction with our specialty instructor training.

We do teach quite a lot specialties at student level. Some of our most popular PADI Specialties include:

  • Deep Diver
  • Wreck Diver
  • Enriched Air Diver
  • Sidemount Diver

We suggest you choose specialties that are either in high demand by potential employers, or in areas in which you are passionate about.

Can I join the team-teaching program if I already hold 5 specialty ratings?

We do get candidates that come to us having already completed their Specialty Instructor Training.

In this case, we recommend that you complete the second part of our MSDT program, that deals strictly with assisting student level courses.

This is a great choice for an Inactive Instructor who wishes to refresh their knowledge and skill level.

We can look at your previous teaching history and choose the courses that would benefit you the most to assist on.

You also have the option to complete additional Specialty Instructor Training, or you can focus on assisting the specialties for which you hold the Instructor rating.

Can the MSDT Instructor rating help to find me a job?

The PADI MSDT rating will improve your chances of finding a suitable job within the dive industry for a number of reasons.

The MSDT rating enhances your skill and knowledge level in addition to demonstrating a commitment to continued training.

Having the ability to teach specialty courses complements your entry level course teaching credentials.

Many customers want to take student level specialty courses in addition to the Open Water course or Advanced Open Water course.

In dive centres around the world, most dive centre operators require instructors that can teach the most popular specialty courses, such as Deep, Nitrox and Wreck penetration courses.

In some cases such as working on live-aboards, you may find that having the MSDT rating is a pre-requisite to employment.
