If a local Post Office needed to hire 10 people, they did not hire the 10 highest scores.
They separated the tests by race, and then ranked them.
If all ten of the top scores were by white or Asian applicants, they chose the two or three Black and Hispanic candidates who scored highest in their own racial group.
There have been have several lawsuits to end race norming.
I do not know if race norming policy is still in force.
“If a local Post Office needed to hire 10 people, they did not hire the 10 highest scores.”
Happened to me in 70. I got out of the Navy and applied for a job in the U.S. Courthouse in Nashville. I aced the test, had 5 points veteran’s preference and they hired two Mexicans that could barely speak English.
I took the civil exam for the USPS back in the day. Blacks and vets got something like 10 points added to their score. I got a 99 and ended up at the bottom of the list for hiring. About a year after I took the test, I received a letter from the USPS stating I could be hired if I agreed to move...to El Paso TX. There was no way I was moving to El Paso. Too far away from all the family and my hubby would have had to give up his job, which he made decent money and had great benefits. Not much of a choice.
