Nursing school letters of recommendation: who to ask and what to do

A strong letter of recommendation supplies specific, observable evidence about your clinical aptitude, work ethic, or academic capability, written by someone with the credibility and context to assess it. Favorable opinion alone carries little weight. Most applicants who get passed over had letters that were generic, last-minute, or written by recommenders who didn’t know them well enough to say anything useful. A specific, personal letter from a community college professor who remembers you by name is worth more than a polished one from a high-profile contact who barely knows you, and admissions readers who see hundreds of letters a cycle can tell the two apart quickly.

Worth keeping in proportion: the American Association of Colleges of Nursing found that US nursing schools turned away 93,176 qualified applications in 2025, citing shortages of clinical placement sites, faculty, preceptors, and classroom space, along with budget cuts. Those applicants had already cleared the grade and prerequisite bars. The pressure is not evenly distributed: 75,255 of those applications were to entry-level baccalaureate programs, against 6,496 to master’s and 9,859 to DNP programs, so a pre-licensure applicant is competing in the most rationed segment of the system. Letters decide outcomes at the margin of a heavily rationed process, which is a good reason to take them seriously and a good reason not to read a rejection as a referendum on your recommenders.

Quick decision guide: who to ask by program type

Most nursing programs ask for two to three letters. The exact number and the mix of academic and clinical writers vary by program, so treat the table as a starting point and confirm each school’s requirements.

Some programs accept extra letters beyond the minimum and others set a hard cap. Follow the instructions precisely: letters beyond the requested number often go unread.

Who writes the strongest letters

The strongest letters come from people who have directly observed you in a clinical or academic context and can speak to specific behaviors and outcomes. Liking you, having known you a long time, or holding an impressive title adds little on its own.

Pre-licensure applicants (ADN, BSN, accelerated BSN, direct-entry MSN)

Academic references. Most programs want at least one letter from a college instructor, ideally from a science prerequisite such as anatomy and physiology, microbiology, or chemistry. A professor who gave you an A is useful only if they know you beyond your grade. The best academic writers had you for a full semester in a setting where they could see your work: office hours you attended regularly, a lab you excelled in, a project or exam that showed what you can do, or a stretch where you struggled and recovered. A professor who graded purely by multiple choice in a large lecture and never learned your name cannot write a detailed letter, whatever grade they gave you. A strong relationship with an instructor in a non-science course (English composition, psychology, statistics) can complement a science reference.

Healthcare supervisors. These carry significant weight because they can speak to your aptitude in clinical environments, which is exactly where nursing programs want to place you. If you worked as a CNA, medical assistant, EMT, phlebotomist, or home health aide, your supervisor has observed you managing patients under stress. An RN who supervised you, a charge nurse or unit manager, or a hospice, long-term care, or home health supervisor all fit here. These letters answer a question academic references cannot: what is this person like when patients are involved? They matter most for accelerated and direct-entry programs.

Non-clinical professional references. If your clinical experience is limited, a non-healthcare employer can work, provided they supervised you directly and can speak to accountability, composure under pressure, reliability, communication, and how you treat people. A retail supervisor who watched you handle difficult customers is more useful than an executive who approved your time sheets.

A college advisor or counselor who worked closely with you through academic or personal challenges can speak to resilience and commitment. Use this as a secondary choice behind a professor or a supervisor.

RN-to-BSN applicants

Your nurse manager or charge nurse has direct supervisory authority and can speak to your clinical competence, reliability, communication with the care team, and patient care quality. This is your strongest letter. A clinical educator who has worked with you in skills training or preceptor programs is also strong.

Peer RNs, even excellent ones, are weak recommenders because they lack supervisory authority. Programs want the view of someone who evaluates your performance.

MSN and NP applicants

NP programs are assessing whether you have the clinical foundation and judgment to function in an advanced practice role. The highest-value letters come from supervising APRNs or physicians who have observed you managing complex patients. Staff RN colleagues can speak only to your general nursing skills.

If you have an NP or physician at your facility who has worked closely with you and who you’ve impressed, this is the priority ask. Their perspective on your clinical decision-making, your ability to synthesize complex information, and your patient communication carries more weight in an NP application than a manager who can speak to your attendance record and reliability.

A faculty member from your BSN program is a useful third letter if you were a strong student and maintained the relationship, particularly if they have clinical knowledge or research experience.

Who to avoid

• Family members or personal friends (never appropriate)
• High-status contacts with no real knowledge of your work
• Anyone from a course, job, or setting where your performance was weak
• People who seem reluctant or unenthusiastic when you ask

If someone hesitates, thank them and move on. A lukewarm letter can hurt your application.

If your academic or clinical network is thin

Students who took online prerequisites, returned to school after years away, or come from non-traditional backgrounds often lack deep relationships with professors. Options:

• Email a professor from a recent course and reintroduce yourself, attaching graded work as a reminder. Many will write for a strong student without a close relationship, as long as they have something specific to reference.
• Lean on clinical references. A supervisor from any direct care role (CNA, medical assistant, home health aide) can be a strong reference without academic credentials.
• Consider a healthcare volunteering reference. Hospital volunteer programs, free clinics, and hospice give you a supervisor who has seen you in a patient-adjacent setting.
• Talk to a pre-nursing advisor. Many colleges have advisors who can help you identify appropriate references and plan the approach.

If you’re concerned about gaps in your application, the nursing school rejection guide and reapplication guide cover what programs weigh most heavily in borderline files.

How far in advance to ask

Ask at least 6–8 weeks before the letter is due, and earlier where you can. Two to three months gives busy clinicians and faculty room to write something considered, especially in the fall and winter when professors field requests from many students at once. Your recommenders have jobs, other students, and competing obligations. A request with two weeks of notice frequently results in a generic, rushed letter or a polite decline.

If you are applying to multiple programs with staggered deadlines: Ask in time for your earliest deadline, explain that multiple programs will send requests, and provide a complete list with every deadline up front.

If you’re applying a year in advance: Some recommenders prefer to write closer to the deadline when the letter is fresh. Ask whether they’re willing to commit now and write when the deadline approaches. Either approach works as long as you get the commitment early.

See the nursing school application timeline for scheduling the rest of your application components.

How to ask effectively

The ask itself affects the quality of the letter. A recommender who says yes to a vague request and then has nothing substantive to work from will write a vague letter. Make the request personal: ask in person or by phone when you can, follow up with a confirmation email, and never send one form email to five people at once.

Ask directly whether they can write a strong letter. That phrasing gives them room to decline gracefully instead of agreeing reluctantly.

Example language for a professor:

“I’m applying to BSN programs this fall and I’m hoping you might be willing to write a letter of recommendation for me. You taught me in Microbiology in Spring 2025 – I was the student who did the biofilm lab project for extra credit. I’d love to include a letter from you if you feel you can speak strongly to my work in that course. My earliest deadline is [date]. Would you be willing?”

What to send once they agree

1. A specific reminder of your shared work. Don’t assume they remember the details. “I worked on your cardiac step-down unit for two years, and you nominated me for the preceptor development program last spring” gives them something to anchor the letter to.
2. Why you’re pursuing nursing and this program. A sentence or two on your motivation and career goal lets the recommender connect your qualities to it: “Her goal of becoming a PMHNP is well-matched to the empathy and precision I observed during her time on our behavioral health unit” is far stronger than generic praise.
3. Your materials. Your resume, a personal statement draft if you have one, and each program’s stated evaluation criteria. Many recommenders use your framing to structure their letter, and a statement draft lets them reinforce your themes without repeating them.
4. The list of programs. This helps them tailor the letter and tells them how many submissions to expect.
5. An optional note on emphasis. “If you’re able to speak to how I handled the ICU rotation, that would be especially relevant” is appropriate. Leave the wording of the letter to them.
6. Submission instructions. Most programs use portal-based submission (NursingCAS or a program-specific portal), and your recommender will receive an email with a link once you add them. Tell them to expect it and to check their spam folder. Physicians and NPs often have administrative staff who need clear directions too.
7. A hard deadline. Give the actual due date, with a small buffer. If the program deadline is March 15, say so rather than “sometime in March.”

What a strong letter includes

Most applicants never read the letters written about them. Knowing what strong letters contain lets you give your recommenders the inputs they need.

Admissions readers look for specificity and fit. Fit means the letter addresses qualities relevant to nursing: clinical judgment, empathy, composure under pressure, communication with patients and colleagues, response to feedback, and the academic capacity for a science-heavy curriculum. Letters that are short, vague, or focused entirely on grades without describing behavior tend to read as weak.

Strong letters are:

Specific. They reference named situations, observable behaviors, and concrete outcomes. “When the patient’s oxygen saturation dropped suddenly during a routine assessment, she identified the likely cause, escalated appropriately to the attending, and stayed present with the patient and family while the situation resolved – demonstrating both clinical acuity and composure under stress” is specific. “She is an excellent nurse who works well with patients” is filler.

Credentialed. They establish the recommender’s authority to evaluate you. A letter from a supervising NP or physician carries implicit authority. A letter from a faculty member should establish the class context and what they observed of your work.

Forward-facing. Beyond describing what you’ve done, strong letters predict what you’re capable of. “I believe she has the analytical rigor, clinical instincts, and dedication to succeed in an NP program and in independent practice” closes the loop between observed past performance and future potential, and it gives an explicit endorsement for the program.

Calibrated. The best letters place you among a cohort: “In 15 years of supervising RN students, she is among the most technically proficient and patient-centered nurses I have worked with.” Only a recommender who sees enough students or nurses to have a comparison can do this.

What to do if you’re asked to draft your own letter

Some recommenders, particularly physicians and NPs with limited time, ask applicants to draft the letter themselves. This is common. Treat it as a writing assignment.

Write in third person, as the recommender writing about you. Focus on specific examples the recommender witnessed firsthand, and do not invent observations they couldn’t have made. Keep a professional distance that matches the recommender’s voice, without self-promotion.

Send the draft with a note: “Here is a draft to work from – please add, subtract, or rewrite anything you’d like. I’ve tried to include specifics from our time working together, but you know best what you observed.”

Recommenders who ask you to draft will typically edit it to reflect their own voice, and the final letter is theirs to approve. The recommender must still submit it personally: NursingCAS will not accept a reference completed or submitted by the applicant (see below).

How to follow up

One follow-up reminder 1–2 weeks before the deadline is appropriate. More than one, unless the deadline is days away, is excessive. Keep the email brief:

“Hi [Name] – I wanted to check in as [Program Name]‘s deadline approaches on [Date]. The submission link was sent to [email address]. Please let me know if you need anything from me. Thank you for your support.”

If the recommender hasn’t submitted two or three days before the deadline, a direct follow-up by phone or text (if the relationship warrants it) is appropriate. If the deadline passes without submission, contact the program’s admissions office immediately; some programs will allow a brief extension for a late letter from a confirmed recommender.

Do not assume submission has happened because the recommender said they would do it. Check the portal yourself.

Application-specific considerations

NursingCAS references. NursingCAS is built around one online application and one set of materials for multiple programs, and the References section appears only for programs that require references. Each recommender receives an auto-generated email with instructions once you add them. Track progress in the application’s status area: a reference moves from Requested (not yet accepted) to Accepted (agreed, not yet submitted) to Complete, with a completion date. NursingCAS states that it will not notify you about missing references, so checking is your job. Set the reference due date before your programs’ deadlines.

Before adding anyone, check each program’s rules on reference roles and relationships. Completed references cannot be removed or replaced, so a letter from the wrong type of writer can’t be swapped out later. If you entered a wrong email address, delete the request and re-add it with the correct one.

References must come from the reference. NursingCAS submits all references electronically through Liaison Letters, its recommender portal, and will not accept a reference completed or submitted by the applicant or by anyone acting on the recommender’s behalf. This matters if you have drafted a letter at a recommender’s request, since the recommender still has to log in and submit it under their own credentials. It also matters for physicians and NPs who delegate correspondence to administrative staff, because the portal link is tied to the named recommender.

Programs can request different reference formats: written responses, a Likert-scale rating form, an uploaded letter, or a combination. Check which one each program uses before you brief your recommenders, because a recommender expecting to upload a letter and finding a rating grid will often submit something thinner than they intended.

The FERPA waiver decision comes first. Before you request any reference in NursingCAS, you must state whether you waive your right of access to it, and NursingCAS does not let you change that selection once made. The Family Educational Rights and Privacy Act gives enrolled postsecondary students the right to inspect letters of recommendation in their education records, and 34 CFR § 99.12 permits you to waive that right for letters used in admission, employment, or honorary recognition.

Waive in most circumstances. Admissions committees can see whether a letter was confidential and tend to weight waived letters more heavily, on the reasoning that a recommender writing without an audience is more candid, and some recommenders will not write a non-confidential letter at all. Two safeguards remain either way: a program cannot require the waiver as a condition of admission or of any other benefit, and even after waiving you can request the names of everyone who wrote for you. Under the regulation a waiver can be revoked in writing, but only prospectively; it has no effect on a letter already submitted.

Programs outside NursingCAS. Schools that use their own application portals collect references separately, so a recommender may need to submit to each one. Clarify this with your recommenders up front, provide the complete list of schools and deadlines in one communication, and confirm they are comfortable with the number of submissions. One portal submission is a small favor; ten separate submissions is a much larger one.

For NP programs specifically: Some MSN programs require at least one letter from a licensed healthcare provider (NP, PA, physician, CNS) who can speak to your clinical practice. Read the requirements carefully. A program asking for a “clinical reference” wants something different from a “professional reference,” and submitting the wrong letter type creates processing delays.

Common mistakes to avoid

Waiting too long to ask. Professors and clinical supervisors write many letters per cycle. Asking in September for an October deadline puts you at the back of a crowded queue.

Assuming someone will say yes without checking. Ask explicitly whether they can write a strong letter.

Not providing enough context. If it’s been more than a year since you worked with someone, remind them of specifics. They may remember you warmly but can’t recall details without prompting.

Using one roster for programs with different requirements. Some programs want all academic references; others want at least one clinical or professional reference. Check each program and adjust your list of writers.

Not checking the portal. A recommender’s promise is not a submission. Confirm the Complete status yourself.

Not saying thank you. After the cycle ends, regardless of outcome, send a personal note to each person who wrote for you, and let them know where you landed. You may need them again for a graduate program or first job.
