Minimum Requirements for the class: Each student must have attended and completed a Basic Latent Fingerprint Comparison Course to be accepted in the Advanced Latent Palm Print Comparison Course. 

 You need to attend this program if...

  • You would like to learn how to recognize valuable search clues for latent palm prints
  • You would like valuable training in latent palm print orientation and comparison techniques
  • You want to understand value of Major and Minor Flexion Creases during comparisons


Many of my students have expressed to me that latent palm prints are very difficult for them to compare. They also suggested that I should develop a palm print comparison course that simulates routine case work type training. This is that class! 

This course combines both lecture and latent palm print comparison exercises. The ACE-V methodology of comparing and identifying latent prints is discussed as it relates to the scientific method. The latent palm print practical exercises in this course will definitely provide a real-life case work type training experience. 

If your goal is to improve your latent palm print comparison skills, this class will provide valuable training to help you achieve your goal.


  • The ACE-V methodology of latent print comparison and identification
  • Palm print topography and its use in comparisons
  • Palm print points of direction, areas, and zones
  • Major and Minor Flexion Creases
  • Palm print orientation and palm print search clues in latent print comparisons
