How to Evaluate a PhD Program After You Receive an Offer

Receiving a PhD offer is exciting! But before you accept, you want to determine if the program, the lab, and your advisor are actually the right fit for you. This post gives you some tips on how to carefully evaluate whether this offer is one you should accept. We'll talk about questions you should ask, who you should talk to, and things to watch out for. If you haven't read the previous post in this series on how to research a PhD program before you apply, it's worth starting there. This post picks up where that one left off.

The visit: Your best evaluation opportunity for your PhD offer

Most PhD programs in the US will invite shortlisted applicants for a visit, either in person or virtually. This visit is often framed as an opportunity for the program to evaluate you, but this is also an opportunity for you to evaluate them, and you should approach it that way. On one of my visits, I could see how anxious and stressed the graduate students were due to how they were funded. I decided that was not a place I wanted to attend. That’s why the visit can be so important in your decision-making process.

For students who are able to visit in person, take full advantage of everything the visit offers. Walk the campus and surrounding neighborhood. Where do most students live? How will you get to campus? How easy will that journey be? Spend time in the department. Notice whether the environment feels like somewhere you could spend the next four to seven years. If you know which lab you will join, hang out with those students. Do you like them? Pay attention to the informal moments as much as the formal ones.

For international students who cannot travel to the US before making a decision, a virtual visit is a good alternative. A video call can serve as a campus tour. Ask to meet with more than one person – the director of graduate studies, for example, and definitely meet with some graduate students (see below), especially those in your future lab. A program that is serious about recruiting you will accommodate reasonable requests.

Regardless of format, come prepared. Know what you want to learn by the end of the visit. Have a list of questions to avoid wasting your time and the time of others.

Talking to current and former students

You absolutely must talk to the advisor's current students before you accept an offer. No other source of information will tell you more about what it is actually like to work in that lab. Talking to former grad students, if possible, can also give you a sense of the advisor’s career mentoring skills, but current students are the most valuable. They can tell you what day-to-day life in the lab looks like, how accessible the advisor is, how feedback is given, and whether they feel supported. Former students, particularly those who have moved on to jobs or other programs, may speak even more freely because they have nothing at stake. Both perspectives are valuable.

For many international students, this kind of direct outreach feels uncomfortable or even inappropriate. In many academic cultures, approaching someone you don't know to ask candid questions about their advisor would be unusual. It is worth knowing that in the US context this is not only acceptable but expected. A program that has nothing to hide will actively encourage you to speak with current students. In fact, most programs will arrange these conversations as part of the visit. If they don't, you should ask.

When you do speak with current or former students, come with specific questions rather than a general request for impressions. Here are some worth asking:

How long does it typically take students in this lab to complete the program? 

This question gets at timeline expectations and advisor support without asking anything that feels confrontational.

How does the advisor give feedback on written work? 

This tells you both about the feedback process and, indirectly, about the advisor's availability and engagement.

How easy is it to get time with the advisor when you need it? 

Availability is one of the most consequential factors in your graduate experience and one of the hardest to assess from the outside. If you have to wait for weeks for feedback, you cannot progress. This will delay graduation.

What do you wish you had known before joining this lab? 

This open-ended question often produces the most candid and useful answers. If the student struggles to answer, you might reframe the question as: Would you join this lab again? Why or why not?

Where have recent graduates from this lab gone? 

Student outcomes are a way to assess how well the advisor prepares their students for life after graduate school.

Questions to ask the advisor directly

Come prepared with questions, and pay close attention to the advisor responds, not just what they say. Remember, you are interviewing them just as they are interviewing you.

Are you planning to continue working in this research area for the foreseeable future?

You want to know that the lab's focus will be stable enough to support your dissertation work from start to finish.

How do you typically structure your meetings with students, and how often do you meet? This question surfaces both availability and management style without asking either directly.

What does your funding situation look like over the next few years? 

Funding supports your stipend, your research materials, and in some cases your ability to attend conferences. It is a practical question and a reasonable one to ask.

How do you prefer students communicate with you when they have a question or a problem?

The answer tells you about accessibility and working style. Some advisors prefer scheduled meetings; others are happy with a quick email. Neither is wrong but consider your preferences as well.

Can I speak with some of your current and former students? 

If an advisor hesitates or discourages this, it is not encouraging. An advisor who is confident in their mentoring record will welcome this question.

On the topic of response times: I touched on this above, but I think it deserves special attention because it has direct consequences for your progress and your graduation timeline. Slow responses from an advisor mean delayed feedback on your writing, delayed approvals on your research decisions, and in some cases delayed dissertation completion.

Ask current students how long it typically takes to hear back from the advisor on something important. The answer will tell you a great deal. For me, personally, I knew I wanted to work in my advisor's lab when he emailed me from China to let me know he had received my message and would respond as soon as he was back. That email told me that he understood his students' time mattered. I had worked in another lab before that one where the advisor never responded to emails but would occasionally stop by the office to answer questions in person. If you weren't there when he came by, your question simply didn't get answered. That lack of communication was extremely frustrating to a lot of students.

Red flags worth taking seriously

Most advisors are doing their best, and most labs are reasonable places to work. But some are not, and it’s better to know that before you sign your contract. Here are some specific things worth watching for.

An advisor who is consistently slow to respond to emails before you have even joined the lab. If they are not responsive when they are trying to recruit you, it’s unlikely to improve once you are a student.

A lab where several students have left without completing their degrees, or where the time to completion is significantly longer than the program average, may indicate a mentoring environment that isn't working for students.

An advisor whose management style sits at one of two extremes, so hands-on that students can't make an independent decision, or so hands-off that students are effectively being mentored by postdocs or left to figure things out entirely on their own, is worth thinking carefully about. Neither extreme serves most students well. When I was a graduate student, I knew of one lab where the advisor was rarely in the country. The graduate students were mentored almost entirely by postdocs. For some students that might work. For most, it isn't what they signed up for.

A final thought

You have worked really hard to receive a PhD offer. This means the program wants you to join. And it feels really good, really validating, to get that offer. But don’t accept it before you have thoroughly evaluated the offer. Think about your stipend amount and the cost of living in your new city. Don’t forget to consider research fit, like I discussed in the previous post here. If you don’t have an interest in your research, it will be so much more difficult to finish your degree.

In the next post in this series, we'll look at mentorship style fit: how different advisors mentor differently, how different students have different needs, and how to figure out whether the two are compatible before you commit.
