<p>The prof I did research with showed me the LOR he wrote. </p>
<p>The only sentence I was concerned with is “I cannot evaluate his (me) academic performance as I did not teach any of his classes.”</p>
<p>That is definitely true. He has not taught me a course, but…is it necessary that he says this in a LOR? it seems redundant to me.</p>
<p>It is pretty standard wording.</p>
<p>It makes him look honest. Often times letter writers will note weaknesses too, in order to show that the letter complete and genuine.</p>
<p>I’d be glad that your reference pointed that out explicitly. Otherwise a critical reader might wonder why your letter didn’t talk about your academic performance - because your performance was below par and your writer didn’t want to hurt you?</p>
<p>I’ve had the same things said in my lors. It’s no big deal - How would they know what kind of a student you are in the classroom without seeing you in the classroom? It’s not negative, just letting the reader know what their experience is.</p>
