Bob Test (BT)

INTRODUCTION

The Bob Test is an assessment tool designed to evaluate an individual's level of comfort or fear when interacting with aquatic environments. It evaluates the willingness to immerse the face and head, but does not take into account the form, technique, or method used to immerse. The Bob Test is primarily designed to be an aptitude test, rather than a proficiency test. This means its primary purpose is to assess an individual’s readiness or capacity for learning skills in an aquatic environment, not their bobbing performance or breath control ability.

The Bob Test is defined as the following:

This test should be performed with at least one hand on the pool deck or wall for support, or while standing in chest deep water. Instructors should not hold students' hands or provide assistance.
