Practical, experience-based training is becoming essential as genetic testing enters routine care.

In 2025, clinicians around the world continued to deepen their engagement with genetic testing — not through abstract theory, but through learning that supports real clinical decisions.

Among 3billion’s educational offerings, Foundations of Genetic Testing emerged as the most widely chosen learning experience of the year. Its strong engagement reflects a growing need for clear, practical guidance on when to order genetic testing, how to interpret results, and how to communicate findings to patients and families.

But for many clinicians, learning did not stop at the fundamentals.

To support continued growth, 3billion offers a structured learning pathway designed to meet clinicians at different stages of experience:

A Learning Pathway for Every Stage

Foundations of Genetic Testing (Beginner)
An entry point for clinicians seeking clarity on genetic testing principles and clinical application.

Building Skills in Genetic Interpretation (Intermediate)
Designed for clinicians ready to deepen their interpretation skills, this course focuses on analyzing results, understanding variant classifications, and applying findings in more complex clinical scenarios.

Approaching the Hard-to-Diagnose (Advanced)
An advanced-level course that explores challenging cases, unsolved conditions, and strategies for navigating diagnostic complexity when answers are not immediately clear.

Together, these courses form a progressive learning journey — supporting clinicians as genetic testing becomes an increasingly integral part of everyday care.

As the field continues to evolve, structured, clinically grounded education remains essential for confident and responsible use of genetic information.
