Instant answer: what is the Swim ABC and how long does it take?

The Swimming ABC Is the official trajectory of the National Swimming Safety Council (NRZ) with which children learn to swim safely step-by-step. In three diploma levels - A, B and C - they grow from water-free to open-water survival.

  • Average lead time at two classes a week: ± 14 months
  • Diploma A → anhydrous + basic strokes
  • Diploma B → endurance + clothes swimming
  • Diploma C → survival skills in deep and open water

1. Why take the full Swimming ABC?

The Netherlands is full of canals, ponds and the sea. Children with only diploma A are still at risk in open water; diploma C is therefore the real flood protection standard. On top of that:

  1. Self-confidence - more easily dare to try water sports later.
  2. Motor development - all four swimming strokes are perfected.
  3. Continuity - regular swimming lessons maintain fitness and technique.

2. Diploma A - water-free & basic strokes
