Before a student is allowed entry into classes or qualifies for the test, he must be at least 10 years old. People under the age of 15 are given junior SCUBA certification that can be upgraded once the student turns 15.
SCUBA is a physically demanding sport. People with breathing conditions or heart disease should not SCUBA dive. People should also be physically fit to paddle through the water and lift the equipment.
One part of the SCUBA certification is being able to float on water for 10 minutes. The student must be able to swim and tread water without any leaning or assistance.
The student is given a book of coursework that must be learned. Part of SCUBA certification is taking a written exam and questionnaire on safety and equipment standards.
The student is taken on his first test dive for certification. Normally, this dive is in approximately 50 to 60 feet of water. The test dive is performed with the instructor in case of any safety hazards or emergency situations.
