Standard (Static) Proficiency Test Design: All forensic practitioners within a laboratory will receive the same test samples with the same expected results. These tests may include some of the same items used in the double-blind version; however, all samples are unique to each testing cycle. Static proficiency tests follow the same purchase deadlines, distribution dates, and answer submission deadlines as their double-blind counterparts.
Declared Double-Blind Proficiency Test Design: Each forensic practitioner will receive a uniquely composed test containing randomly selected known and/or unknown items. The correct answers are specific to each test, preventing participants from gaining information through discussion with others or with test administrators. These blind elements are built into the test design to reduce bias and increase the integrity of results. Please note that Forensic Assurance tests are declared, meaning the participant is aware they are taking a test.
