LOR - How many schools per prof?

<p>I'm applying to ChE Ph.D. programs in the fall. I was just wondering, what's an appropriate number of schools to ask a busy, pretty famous professor to send a recommendation to? I was thinking about applying to 7 - is that too much to ask of a professor? I have three obvious choices for the professors who would write my recs (two research advisors and the prof for the freshman class I TAed), but after that I'd have to go with professors who know me only from teaching me in a single ChE class, which I don't necessarily want to do.</p>

<p>Thanks in advance. :)</p>

<p>Well - why can’t they just send the same letter or maybe slight variations to like 7-10, hell, 15 schools. Just upload it onto the website. So long as you ask them in advance, I don’t see the problem. It is not like their opinion should change based on the school you apply to… right? I’m probably going to ask my PI to send it to 10-12 schools, maybe even 13.</p>

<p>Hi,
I’ve heard there is some organizations or sites that applicants may request their recommander to submit a LOR for them, and they send LOR to as many as universities applicant wants. Thus applicant’s professor submits one LOR, but the organization sends it to many universities. Is it true? I wish there exist such organizations…</p>

<p>Well it seems most schools just sent a promt or something to the people you put down as your refs and they have to follow a link and basically submit it. So yes, they would do it for like 12 schools, but if you are organized, it shouldn’t be too bad.</p>

<p>Tatat, it is called Interfolio. For some disciplines, this might work. For others, most graduate schools have specific online places for professors to upload letters of rec.</p>

<p>But no one should worry about asking for several letters of rec from each professor. We write one letter for each student, and then tweak that letter a bit to fit each institution.</p>
