Ensuring Fairness Through Item Analysis
Before finalizing test items, an extensive review process was conducted to ensure fairness across ability levels and groups of people. Several steps were taken to achieve this:
Comprehensive Bias and Sensitivity Reviews
To maintain inclusivity and fairness, the WJ V content underwent extensive bias and sensitivity reviews that were conducted by experts with a variety of areas of expertise. This included professionals with expertise in areas such as:
English learners
African American, Hispanic, Indigenous/Native American communities
Individuals with disabilities (e.g., vision or hearing impairment, dyslexia)
LGBTQ+ representation
These experts examined the item content and format to make sure there was no potential bias or sensitivity issues for subgroups of people, such as women, individuals with certain disabilities, and cultural or linguistic minorities 
Special attention was given to the WJ V Achievement tests to verify that constructs were accurately measured and appropriately challenging for each targeted population.
