Swimming Certificates for Kids in the Netherlands

Why Swimming Lessons Are a Big Deal in the Netherlands

With its vast network of canals, lakes, and waterways, the Netherlands takes water safety seriously. That’s why swimming certificates—known as zwemdiploma—are a key milestone for children growing up here. Many Dutch schools even offer swimming lessons as part of the curriculum.

What Are Zwemdiploma A, B, and C?

The official swimming certification program in the Netherlands is called the National Swimming Diploma Programme (Nationale Zwemdiploma). It consists of three levels:

• Diploma A: Basic swimming skills including floating, treading water, and swimming in clothing.
• Diploma B: Builds on A with improved technique, stamina, and underwater swimming.
• Diploma C: Considered the “safe for open water” level, covering strong swimming and emergency techniques.

At What Age Do Kids Start?

Most children start swimming lessons around the age of 4 or 5. The path to earning the A diploma can take 1–2 years, depending on the child’s progress and lesson frequency.

Are Swimming Certificates Mandatory?

They’re not legally required, but practically essential. Many schools, summer camps, and public pool facilities ask for at least an A diploma for participation. For parents, it’s also peace of mind around the country's many water hazards.

Where Can Kids Take Lessons?

Swimming lessons are widely available at local pools, sports centers, and through private instructors. Municipal pools often follow the official diploma curriculum. Lessons are typically taught in Dutch, but many facilities are used to working with expat children.

What’s the Cost?

Prices vary by region and facility. On average, expect to pay between €8 to €15 per lesson. Some municipalities offer financial support for families who need it.
