Sample Set Description: Each proficiency test design will include two evidentiary mixture samples (2, 3, or 4 person mixtures) and four known samples. The samples will be processed either per laboratory system, laboratory, or instrument depending on your technical leaders input. The generated data files will be distributed to the corresponding scientists for analysis. Participants are requested to compare each known sample to the mixture samples utilizing your current probabilistic genotyping software and procedures. Each participant will need to determine the number of contributors to each evidentiary sample, the likelihood ratio of each comparison, and which hypothesis each likelihood ratio favors (prosecution or defense).

The purchase of the Probabilistic Genotyping Software Proficiency Sample Set includes online answer sheet login credentials for two participants.  A sample set must be purchased to accompany the additional participant login credentials.
