Recommendation Letter For Instructor

Writing a Recommendation Letter That Actually Carries Weight

I spend about half my week drafting or reviewing recommendation letters for instructors applying to programs, promotions, or department chairs. Most of them are fine on structure but weak on substance. The difference between a letter that opens doors and one that gets filed unread usually comes down to three things: specificity, measured tone, and an honest assessment of fit. Here is how to actually do it. Start by clarifying what kind of letter you are writing. An instructor recommendation letter can serve different purposes—course release, tenure track promotion, a fellowship, administrative appointment, or external hiring. The content shifts meaningfully depending on which one. A letter for a teaching-focused position will weigh student outcomes and curriculum design differently than one for a research-intensive role. I once had a colleague send a heavily research-weighted letter for an instructor applying to a community college teaching position. It tanked the application. They put someone in charge of introductory labs who had never managed a classroom at that level. The department chair rejected the candidate politely but firmly afterward and sent me a follow-up email about it. I learned to ask upfront what the application is for before drafting anything. You cannot write a credible letter from memory alone. Instructors teach dozens of sections, run office hours, grade papers, advise students, and handle administrative work simultaneously. Even if you have known someone for five years, you will miss concrete details without documentation. Request specific evidence from the instructor: a current CV, a course syllabus, student evaluation summaries, copies of teaching materials, and a brief self-narration of their most significant accomplishments since you last spoke. I always ask for student evaluation data in aggregate form rather than individual comments. Individual comments are noisy and often legally sensitive. Aggregated data—mean scores, response rates, trend lines across semesters—is far more useful and appropriate to reference.

I also pull my own records when possible. If I taught the person or supervised them directly, I look up assignment prompts, rubric versions, and any peer observation notes I have on file. These details let you describe what their course actually looked like rather than saying they were good at teaching. Saying they were good at teaching is the opposite of what the reader needs.

Structure That Works Without Sounding Generic

A standard recommendation letter has a predictable shape: opening context, body paragraphs covering teaching, research or service depending on the goal, closing endorsement. The trap is making every paragraph sound like the same boilerplate letter you wrote last year. To avoid that, I organize around competencies that matter for the specific role. For a teaching promotion, I structure around course design, classroom management, student feedback response, and instructional innovation. For research positions, I shift to methodological rigor, publication trajectory, grant activity, and mentoring of graduate students. The structure itself signals that you actually considered what the selection committee cares about. Each paragraph needs at least one concrete, verifiable example. Not a single anecdote per paragraph—real letters have multiple. Here is a practical way to build them without repeating yourself: use the situation-approach-outcome format. State what the instructor was responsible for, describe what they changed or implemented, and give the measurable result. Keep it tight. Three sentences per example is enough if the detail is sharp. I include a specific war story here because it matters. I recommended an instructor for a department chair position who had a reputation for being difficult with graduate students. I could have written a vague letter praising their dedication. Instead, I described a concrete incident: the instructor restructured the qualifying exam process after receiving formal complaints about inconsistent rubric application. They produced a revised scoring guide within six weeks, held training sessions for the committee, and published a short methods note in the department’s pedagogical journal documenting the changes. The result was not that they were suddenly nice. The result was that they demonstrated corrective action under pressure, which is exactly what a chair needs. That paragraph carried more weight than ten generic statements about work ethic. I learned to stop avoiding the hard parts of a recommendation. Omitting known weaknesses does not protect the candidate. It makes the letter look dishonest, and committees spot that immediately.

Tone and Language Choices

Write in plain academic prose. Avoid superlatives unless you can prove them. Words like "extraordinary," "truly exceptional," or "one of the best I have ever seen" are meaningless without scaffolding. If you use a strong descriptor, back it with a comparison to a recognizable group. "Top ten percent of instructors I have supervised in twenty years" is specific. "Top ten percent" is defensible. "Best ever" is not. I also avoid passive voice where possible. Passive constructions dilute accountability and make it harder for readers to assess your credibility as a recommender. "Student feedback was positive" tells the reader nothing. "My student evaluations averaged 4.6 over three semesters, compared to the department mean of 4.1" does. Keep the letter between one and two pages unless the application explicitly requests more. Selection committees read dozens of these in a single day. Dense, specific paragraphs beat padded prose every time. I typically draft to about eighteen hundred words and then cut it to twelve hundred during revision. The cut usually removes adjectives, repeated examples, and boilerplate praise that sounds good in isolation but adds nothing to the overall case.

Common Pitfalls That Sink Letters

The most frequent mistake I see is confusion between the instructor and the writer. Letters sometimes read as though the writer is applying for the job themselves. Every sentence becomes about the recommender's perspective rather than the candidate's actual performance. Fix this by keeping the candidate as the grammatical subject whenever possible. "Dr. Chen redesigned the lab sequence" is clearer than "I observed Dr. Chen redesign the lab sequence, which I found impressive." Another common error is mixing time frames. I recommend anchoring every claim to a specific period. "During the 2022-2023 academic year..." or "In her third year of teaching..." This prevents the reader from assuming you are describing achievements from five years ago as if they are current. I once caught myself writing a letter where the candidate's major curriculum overhaul was dated 2019, but I had not specified the year. The search committee assumed it was recent and weighed it accordingly. When I corrected it, the letter lost nearly half its persuasive power. Dates matter more than you think. A third pitfall is failing to address the selection criteria. Many applications publish explicit criteria: teaching effectiveness, scholarly activity, service, equity engagement, leadership potential. If the letter does not map onto those criteria, the committee has no framework for evaluating it. I always cross-reference the criteria before submitting. If a criterion is absent, I either note it briefly and explain why, or acknowledge it directly rather than silently ignoring it. Silence reads as avoidance.

Where This Approach Breaks Down

This method assumes you have sustained, observable contact with the instructor. If you only taught them once or served on a committee they sat on for a single semester, do not write a letter pretending you know them well. Committees can tell when the evidence is thin. In those cases, decline the request politely or write a letter limited to the scope of your actual interaction. A short, honest letter is better than a long, inflated one. I have seen instructors rejected because their recommender overstated the depth of their relationship. The rejection reason was rarely stated explicitly, but the pattern is consistent across multiple departments I consult for. Another limitation is cultural variation in teaching practices. If the instructor comes from a different educational system or teaches in a non-traditional format—online asynchronous courses, community-based learning, hybrid models—standard evaluation metrics may not capture their effectiveness. In those situations, I adjust the language to reflect the actual context rather than forcing their work into a traditional classroom framework. I also note the context explicitly so the committee understands why certain benchmarks do not apply.

Final Steps Before Submission

Before you send anything, verify the following: the letter is addressed correctly with the right title and department; all dates and numbers match the instructor's records; there are no typos in names or institutional affiliations; and you have included your own contact information so the committee can follow up if needed. I also save a copy with a redacted version of any sensitive student data removed.FERPA compliance is not optional, and I have had colleagues pulled up before the review board for forwarding unredacted evaluation summaries. The process usually takes me about ninety minutes from start to finish when I have all the materials ready. Drafting takes forty-five minutes. Verifying details and cutting fluff takes another thirty. Redacting sensitive information and finalizing formatting takes the rest. If I am starting from scratch without the instructor's documentation, it can take two to three hours because I am hunting for specific course records and cross-referencing dates. A recommendation letter for an instructor is not a formality. It is an evidentiary document. Treat it like one and the rest follows naturally.
