For most of the American public, police officer training aptitude tests are rarely within the public domain - regardless of how well constructed, difficult or easy they are.
If more highly trained or trainable police officers are desired by the police enforcement industry (or Federal, States, and Towns), proactive methods could be used to induce applicants to explore the field.
To prevent the deductive reasoning that supports the fact that police officer training is by inheritance or nepotism and affiliation, it might be necessary to more publicly display the intention of departments to actively solicit qualified applicants in such a manner rather than relying upon referral and chance to fill departmental needs.
Since police officers are a highly visible segment of American society, and many youth wonder if they might be police officer material, inaccessibility to preliminary police aptitude testing resources serves the purpose of not getting those fine candidates.
In the interests of expert candidates as well as to provide the best in the field, proactive methods of recruitment is an area of law enforcement orientation that could, and perhaps should be done for the public to acquire the best and brightest in the field, and within the hierarchy of the industry - that includes both adult men and women.
