What education level is represented by a person who has completed only the 8th grade?

A person who has completed only the 8th grade is typically considered to have attained a limited level of education. This designation recognizes that while they have received education up to a certain point, they have not completed high school or pursued further education such as college.

Choosing "limited education" reflects an understanding that completion of the 8th grade does not equate to high school graduation or higher educational milestones. It indicates a foundational level of education, but acknowledges the absence of higher qualifications or degrees.

Meanwhile, options like high school graduate and some college education clearly exceed the educational attainment of completing just the 8th grade, while middle school education is generally understood to encompass grades typically involving 6th through 8th, thus not appropriately describing the level of completion beyond that scope. Therefore, "limited education" is the most fitting option.
