The student has written the following:

This description is very broad, but the measurement of intelligence has been very narrow before, which didn’t allow for others to be included as intelligent.

There are three verb tenses in this sentence: the present tense ("is"), the present perfect tense ("has been"), and the past simple tense ("didn’t allow"). The word "before" and the use of past tense at the end of the sentence ("didn’t allow") suggest that the middle verb, "has been," is not correct—that verb should take the past tense, as well. The student could correct this error by writing,

This description is broad, but the measure of intelligence was very narrow before, which did not allow for others to be included as intelligent.
