Yes, I learned about this about 25 years ago when a friend of mine took over command of the remedial school at Ft. Bliss, TX.
“...I learned about this about 25 years ago...”
It was over 40 years ago for me as a brand-new Second Lieutenant who was tasked with ensuring the soldiers in my artillery battery could pass the written portion of the then-new Skill Qualification Test for their specific military occupational specialty. The reading deficiencies were glaring and it was covering material the soldiers had already experienced in their job training after Basic. The NCOs were in charge of preparing them for the hands-on portion of the qualification test.
