Diving with kids: age, safety and certifications

One of the most common questions parents ask is: "How old does my child have to be to try scuba diving?" The answer is younger than most people expect. PADI has structured programmes for children starting from age 8, with clear safety frameworks, depth limits and supervision requirements at each stage. This guide explains every option, from pool-only experiences for 8-year-olds to full Junior Open Water certification for 10-year-olds, so you can decide what is right for your family.

What is the PADI Bubblemaker programme for kids aged 8 and up?

The PADI Bubblemaker is the very first structured diving experience available to children. It is designed for kids aged 8 and 9 and takes place exclusively in a pool or confined water environment with a maximum depth of 2 metres. It is not a certification course; it is a supervised experience that lets children breathe underwater for the first time in a completely controlled setting.

During a Bubblemaker session, children use child-sized scuba equipment (smaller BCDs, regulators with softer mouthpieces, and lighter tanks). The instructor stays within arm's reach at all times. The session typically lasts about an hour, including a briefing, equipment familiarisation, and time in the water. Children learn to breathe through a regulator, clear their mask, and move around underwater.

There is no swimming test requirement, but the child must be comfortable in the water and willing to participate. No child should ever be forced or pressured into diving. If they are scared or resistant, it is better to wait. The experience should be entirely positive, because a bad first experience can turn a child away from diving for years.

Key facts: age 8+, pool only, 2m maximum depth, no certification, approximately 1 hour, typically 30 to 60 euros.

Can children aged 8 to 9 dive in the sea?

Children aged 8 and 9 can participate in the PADI Discover Scuba Diving (DSD) experience in open water, with a maximum depth of 12 metres. However, many instructors prefer to keep 8 to 9-year-olds in confined water (pool or very shallow, protected areas) for their first experience, particularly if the child has never been in the sea with a mask before.

The decision depends on the individual child. Some 8-year-olds are confident, strong swimmers who are eager to see fish and turtles. Others are more hesitant and benefit from a pool introduction first. A good instructor assesses each child individually and adapts the plan accordingly. At Dive With Lau, we always speak with parents beforehand to understand the child's personality, water confidence and any concerns.

If you are planning a family holiday and want to include diving for younger children, destinations with warm, clear, calm water are essential. Tenerife and Greece are both excellent choices for families, with sheltered bays and marine life accessible from very shallow depths.

What is the Junior Open Water Diver certification for 10 to 14-year-olds?

From age 10, children can enrol in the full PADI Open Water Diver course and earn the Junior Open Water Diver certification. The course content is identical to the adult version: eLearning theory, confined water skills practice, and 4 open water dives. The key differences are the depth limits and supervision requirements:

• Ages 10-11: maximum depth of 12 metres. Must dive with a certified parent/guardian or PADI professional.
• Ages 12-14: maximum depth of 18 metres (same as adult OW). Must dive with a certified adult.
• At age 15: the Junior certification automatically upgrades to a full Open Water Diver certification with standard adult depth limits.

The eLearning is the same material used for adults. Some 10-year-olds find it challenging, particularly the physics and physiology sections. Parents can help by working through it together. The practical skills in the water are generally where kids excel; they tend to be more relaxed and adaptable underwater than adults because they have fewer preconceptions and fears.

Duration: 3 to 4 days. Cost: same as the adult Open Water, typically 300 to 600 euros. Equipment is usually included and must be child-sized.

Can teenagers do the Advanced Open Water?

Yes. From age 12, children can enrol in the Junior Advanced Open Water Diver course. The format is the same as the adult version: 5 adventure dives over 2 to 3 days, including the mandatory Deep Dive and Navigation dive.

The depth restrictions for the Junior AOW are:

• Ages 12-14: maximum depth of 21 metres (compared to 30m for adults).
• At age 15: the certification upgrades to the full AOW with a 30m depth limit.

The Advanced course is actually an excellent next step for a motivated teenager who enjoyed their Open Water. The adventure dives, particularly night diving, wreck exploration and underwater photography, keep the fun factor high while building real skills.

What are the safety considerations for children diving?

Diving with children requires additional attention to several factors:

Physical maturity: children's bodies are still developing. Their Eustachian tubes are narrower, which can make ear equalisation more difficult. Cold tolerance is lower because they have less body mass and less subcutaneous fat. Shorter dives and warmer water temperatures are advisable. In Tenerife (20-24 degrees in summer), a 5 mm wetsuit with a hood is usually sufficient for children.

Emotional readiness: this is often more important than physical readiness. A child must want to dive, not be diving because a parent wants them to. Signs that a child is ready include genuine curiosity about marine life, comfort with face submersion and snorkelling, and the ability to follow instructions and communicate calmly.

Air consumption: children use less air than adults due to their smaller lung capacity, which can be an advantage. However, they also get cold faster and tire more quickly, so dive times should be adjusted accordingly.

Medical considerations: a medical clearance from a doctor is strongly recommended before any child begins diving. Ear, nose and throat issues are the most common concern. Children with a history of ear infections should have a specific assessment. Asthma is not an automatic disqualification but requires medical evaluation and stable management.

Equipment: child-sized equipment is essential, not optional. A BCD that is too large cannot properly control buoyancy. A regulator with an adult-sized mouthpiece is uncomfortable and unsafe for small mouths. Any reputable dive centre that works with children will have appropriate youth equipment.

How do you choose an instructor for your child?

Not every diving instructor is equally suited to teaching children. Look for these qualities:

• Patience: this is non-negotiable. Children need more time, more repetition, and more encouragement than adults.
• Small groups: a ratio of 1 instructor to 2 children is ideal. Never accept a group of more than 4 children per instructor.
• Experience with children: ask specifically about their experience teaching kids. Some instructors are excellent with adults but lack the playfulness and flexibility that young divers need.
• Communication with parents: a good instructor will talk to you about your child's readiness, keep you informed during the session, and give honest feedback afterwards, including if the child was not ready.
• Proper equipment: they should have dedicated child-sized gear, not adult equipment that they "make work."

At Dive With Lau, we welcome families and adapt every session to each child's age, maturity and comfort level. Our groups never exceed 4 people, and for children, we often work one-on-one.

What is the certification pathway for young divers?

Here is the complete PADI certification pathway for children and teenagers:

• Age 8: Bubblemaker (pool, 2m max) and Discover Scuba Diving (12m max with instructor).
• Age 10: Junior Open Water Diver (12m max, must dive with certified parent/guardian or PADI pro).
• Age 12: Junior Open Water Diver (18m max, must dive with certified adult). Junior Advanced Open Water Diver (21m max). Junior Rescue Diver.
• Age 15: all Junior certifications automatically upgrade to adult equivalents. Full depth limits apply.
• Age 18: eligible for the Divemaster and professional-level certifications.

The bottom line

Diving is one of the most powerful experiences you can share with your children. It teaches respect for the ocean, builds confidence, develops problem-solving skills, and creates memories that nothing else can match. The key is to start at the right age with the right instructor, never push, and let the child set the pace.

If your child has ever watched a nature documentary about the ocean and said "I want to do that," they are probably ready.
