Choosing A Commercial Diving School

Before attending any trade school, you need to do your homework. While this list can get you started, there are a lot of things to consider before attending.

  • Do a search in Google. Reddit, Quora, or educational sites to see what others say about the school.
  • Make sure it holds the accreditations it says it does.
  • For diving schools, they should be accredited by the Association of Commercial Diving Educators (ACDE).
  • Check to see if they offer job placement.
  • Is financial aid an option?

Why A Specialized Diving School Is A Better Option

This list includes some specialized diving schools as well as some community colleges. For this specific career we would highly recommend you attend a specialized school that only focuses on commercial diving instruction.

Most community colleges will not have all the required tools and real-world emulators that a commercial diving school can provide.

Because of the dangers of diving jobs, it is critical to have the decompression chamber experiences, real-world welding experiences underwater, and that you learn from people who have done the work you want to do.

The costs may be higher, but the return on investment for this career is very high!

Other School Information

There were a few other diving schools that you might see on other websites, but they are either closed or have had some issues.

We wanted to make sure you are aware of these schools:

  • Divers Academy International (NJ) – closed permanently effective 12/30/21
  • CDA Technical Institute – website is down and they seemed to have a very bad reputation, read story here.
  • The International Diving Institute (SC) is permanently closed as of August 2021.

This is why it is so important to really evaluate any school you are considering attending!
