What is the American Classification System primarily used for?

The American Classification System is primarily designed to facilitate the systematic use of fingerprint evidence for the organization and retrieval of criminal records. This classification system allows law enforcement agencies to categorize and store fingerprints in a manner that enables efficient searching and matching against existing records, making it easier to identify individuals involved in criminal activities.

By establishing a standardized method for classifying fingerprints, the American Classification System enhances the accuracy and reliability of fingerprint identification. It helps in maintaining a comprehensive database that can be used to quickly identify known offenders or link individuals to various crimes, thus playing a crucial role in criminal investigations.

The other options do not accurately reflect the primary purpose of the American Classification System. For example, it does not focus on determining the age of fingerprints or organizing physical descriptions of criminals. Additionally, while it might aid in identifying people, it is not employed for diagnosing skin diseases, which falls under the domain of medical examination rather than forensic science.
