This 10-hour e-learning plus 4-day field training course is designed to teach you everything you need to know to conduct coral reef monitoring dives using the Reef Check protocol. In this program, you will learn all about the globally standardized Reef Check methodology. You will also learn to identify key indicator fish, invertebrates, and substrates selected by Reef Check for global monitoring and conservation of coral reefs. This course will allow you to join the Reef Check monitoring team at our Reef Check expeditions. You will be assisting scientists in evaluating coral reef health in Colombia and around the world.

Reef Check Colombia

Theory component

There are five e-learning sessions where you learn about the fundamentals of coral reefs and coral reef monitoring. This includes their function and importance. You’ll then go on to learn about the driving forces behind the decline of coral reefs and what measures we take to halt this decline. Then, the course continues with an introduction to Reef Check and the Reef Check protocol for coral reef monitoring. This includes the tools, terminology, key concepts, and methods used in the field for monitoring the health of coral reefs with Reef Check. Next, you will learn to identify the indicator species used in your region to estimate coral reef health and the methods to survey them. This will allow you to get an in-depth view of fish, substrate, invertebrate, coral disease, and impact identification for monitoring.

You first will be taken snorkeling or diving to test your skills learned. You will start with a check-up session to test your swimming and or SCUBA diving skills. Next, your knowledge to identify and survey fishes, substrate categories (corals, sponges, algae, etc.), invertebrates, and coral diseases will be applied and tested in three separate open water sessions. Then, all knowledge and skills learned will be put into practice in your last dive where you will conduct a full Reef Check survey. Finally, you will experience capturing and interpreting the data on coral reef health collected by you and your team.


You don´t need to be a certified scuba diver to take this e-learning course. You need to be 12 years old or older. If you only want to experience Reef Check you can start with the Discover Reef Check program.

Testing and Certification

There is a knowledge test you must pass with an 80% score.  This should be done before joining any field training program. The field training has a knowledge ID onsite test (80% to pass) and a field ID test (90%) to obtain regional certification. The certification qualifies you to participate in Reef Check surveys in the region and to submit their data to the global database. An optional certification card is available.

If you are already an EcoDiver and would like to transfer to a new region (e.g. Pacific to the Caribbean), you will need to pass the identification tests. The purchase of the EcoDiver materials for that region is also required. Please contact or for details.

Responsible Diving System for responible reef useAs part of our mission, Corales de Paz believes that there are three distinct components for creating a snorkeling and diving industry that has a net positive environmental impact. The three components are knowledge, skills, and behavior, and together form the Corales de Paz Responsible Diving System which helps you ensure that you always put more than what you take from coral reefs.

A reef user like you, (e.g. beachgoer, snorkeler or diver) must have a proper foundation of knowledge to understand how coral reefs function, and their strong connection with humans, to be aware of the impact you are causing to coral reefs. Practical training offers you the opportunity to develop the skills necessary to measure and reduce the impact caused on coral reefs.

Your introduction to Meaningful Diving!

The Reef Check EcoDiver course is the second level of the Reef Check EcoDiver program and an entry-level in our Meaningful Diving Universe, a group of courses and training we believe provides important knowledge and skills for the ocean lovers and reef users like you to actively engage in building coral reef resilience.
