Good news! No one who hates you will agree to write you a Letter of Recommendation. It's too annoying of a task to bother with if you don't have nice things to say about someone. Still, some letters can be lackluster, especially if they're rushed or overly general.
The University of Chicago Law School admissions blog describes a “standout” recommendation letter as one that provides, “specific and substantive discussion of your abilities as a student.” They look for “a discussion of particular examples of your work, possibly a research project or substantial piece of writing” and/or “qualitative comparisons to your peers and illustrative anecdotes.”
There are ways to make sure recommenders are talking you up effectively. Here’s how to make the ask.
Individualize your approach. What do you know about your potential recommender? Are they someone who will want a face-to-face conversation about this? Or are they someone who will be open to an email with an updated CV attached?
Remind them of your accomplishments. You're not telling them what to write—and they may well choose to highlight some of your other victories or qualities—but offering them a refresher to reference will make your request less of a burden. Your professors know the drill of writing law school references, but they have a lot of students, so a reminder of what you've done is still appreciated. Ex. "It was a privilege to be in a graduate course as an undergraduate. Attending office hours deepened my understanding of the material and provided me insight into strengthening my arguments for the paper, on which I earned an A. I also found that working with a group on the research project honed my abilities in research and developed my collaboration and leadership skills."
While you will want at least two of your recommendations to be written by those who can speak to your academic performance, you may also include a letter from a supervisor at a job or legal clinic where you volunteered. In this request, you want to tell the manager what it meant to you to work there and how you thrived. Ex. "Your recommendation would mean so much to me because this job reinforced my interest in the study of law. Working to support pro-bono immigration cases gave me a better understanding of the day-to-day work of a lawyer as well as additional insight into the necessary research and client-interaction skills required." OR "Working as an analyst in this consulting firm gave me significant experience with project and time management, developed my written and oral communication abilities, and improved my analytical skills. Over time I have increased my responsibilities. This summer I took on the role of team lead and now run weekly client meetings and oversee the analytic strategy and initial creation of client deliverables. I have also made myself available to newer project staff for mentoring and support.”
If you're asking for a recommendation from someone who has never written one, loop them in on the qualities law schools are looking for and how you've exemplified them. Ex. "The schools that I am applying to value critical thinking and problem solving abilities, writing skills, and intellectual curiosity. I believe that my final group project on the early work of Chaucer showed my abilities in those areas.”
Go beyond the ask. After someone agrees to be your recommender, you're going to send them a "game plan" that gets into the experiences you’ve had and your accomplishments in greater depth than you did in your initial request. For example, the student who highlighted the Chaucer project can remind their professor what aspects of the presentation they worked on and reiterate that they organized the group's study sessions. You might also attach a copy of the associated paper that you submitted with your contributions highlighted. The applicant who was a consultant should list their daily duties and talk about some of their most poignant or analytical learning experiences. You get the gist.
Say thank you in a unique way. Once someone has agreed to write your recommendation, do something nice for them. Send a memorable note, maybe even a small gift (a box of their preferred tea or some candy is nice) or offer to take them to lunch. This is common courtesy, but it's also going to remind them to submit their letter on time.
