Gender research results can be used to examine characteristics of groups, not to predict success or failure of individuals. Ability levels can and do overlap between the sexes.
(Halpern, 2000)
Caution

Not one ability, consists of many abilities. It is the skill in visualizing, creating, manipulating, rotating, perceiving, and remembering information in nonverbal and symbolic forms.
Spatial ability requires representation, rotation, and inversion of objects in 3D when they are presented in 2D.

Long term prosperity of our Nation will increasingly rely on talented and motivated individuals who will comprise the vanguard of scientific and technological innovation.
Every student in the U.S. deserves the opportunity to achieve at his or her full potential.
Two Reasons for the Report

Current verbal and mathematical assessments would miss 70% of students scoring in the top 1% of spatial ability
90% STEM doctorate holders scored in the top quartile of spatial ability during adolescence

If the information was about the injury from an employee perspective, it was judged to be not relevant.
