The minimum age is 12 years old, Student divers who are younger than 15 earn the PADI Junior Open Water Diver certification, which they may upgrade to PADI Open Water Diver certification upon reaching 15. Children under the age of 13 require parent or guardian permission to register for PADI eLearning
All student divers complete a brief scuba medical questionnaire that asks about medical conditions that could be a problem while diving. If none of these apply, sign the form and you’re ready to start. If any of these apply to you, your doctor must, as a safety precaution, assess the condition as it relates to diving and sign a medical form that confirms you’re fit to dive
Before completing the PADI Open Water Diver course, your instructor will have you
demonstrate basic water skills to be sure you’re comfortable in the water, including:
Swim 200 metres/yards (or 300 metres/yards in mask, fins and snorkel) without stopping. There is no time limit for this, and you may use any swimming strokes you want.
Float and tread water for 10 minutes, again using any methods you want.
