Falsely allege? The very first sentence of the article says:
It says students. Are those:
a. Kindergarten students.
b. Elementary school students.
c. Middle school students.
d. High School students.
e. College students.
By all means help me out here in which students are failing the exam. I await your answer.
According to the linked article, those who completed High School "recent high school graduates".
Let me quote a specific passage in from the OP article's:
The report by The Education Trust found that 23 percent of recent high school graduates don't get the minimum score needed on the enlistment test to join any branch of the military. Questions are often basic, such as: "If 2 plus x equals 4, what is the value of x?"
The military exam results are also worrisome because the test is given to a limited pool of people: Pentagon data shows that 75 percent of those aged 17 to 24 don't even qualify to take the test because they are physically unfit, have a criminal record or didn't graduate high school.
Educators expressed dismay that so many high school graduates are unable to pass a test of basic skills.
I think it's pretty clear about that a large percentage of high school graduates fail to reach the minimal score on a relatively easy test.
Example of ASVAB's questions:

and here if you want to take it all:

IMHO high school graduates should fly over those questions (if they take them seriously enough).
I assume that the people failing, in this case, took the test seriously because they were trying to enter the service (from the article "Nearly one-fourth of the
students who try to join the U.S. Army fail its entrance exam").
I remember that when I did take the entry exam for navy academy in Italy (I got the needed score) the main problem was not the level of complexity of the test but the very limited time to complete it.
You can get very nervous about it (especially because we were not allowed any watch), high schools in Italy do not use that type of tests, you have only one shot at it, and there are very little places available compared to the number of applicants per year.
Anyway, just for fun, I will give a try to the ASVAB that is online... I wonder of rusty I am after many years after school.
