GPA Has Little Influence on the Outcome of Most Applications to Graduate School in Psychology

One of the recurring themes on this blog is that getting into graduate school requires more than just a good GPA. We have previously explored reasons why grades are only a minor determinant of what happens with most applications to grad school, and we have discussed other key aspects of preparing a successful application.

Today, I will use actual data to show just how little influence the GPA had on the outcome for one large sample of applicants to a particular graduate school in Psychology. In the process of analyzing the data, I will attempt to dispel two widely cited myths about what is needed to get into grad school in Psychology:

Myth #1:  Someone with a GPA around 3.8 has a substantially better chance of being admitted than someone with a GPA that is closer to 3.5. This seems like it must be true, but as you will see in the data, it is not necessarily so. The particular GPA values being contrasted here (3.80 and 3.50) are rather arbitrary, as the point will simply be to show how little influence the GPA has, unless it is an exceptionally high GPA and the student is awarded a scholarship.

Myth #2: Higher grades are needed to get into a clinical psychology program than to get into a non-clinical or experimental psychology program. Most psychology students and many professors hold this common misconception. I used to believe it, too. So, for many years, I was just another misguided psychology professor when it came to this issue. That changed one day when I tried to confirm the rhetoric with some real data.

The table below shows three columns of GPAs. The first thing I want to point out is that some are higher than 4.0, which might seem strange if you are used to seeing GPAs only on the familiar and widely-used grading scale that ranges from 0.0 – 4.0. A variety of grading systems are used in North American colleges and universities, including percentages, A – F letter grades, the familiar 0.0 4.0 scale, and others. The data in this table are from Concordia University, in Montreal, where the grading scale ranges from 0.0 – 4.3. No matter where grad-school applicants did their undergraduate studies, their transcript grades will be converted to this scale when they apply to any graduate program at Concordia. Details of how the conversion is done are beyond the scope of this blog post. But, a GPA on the standard 0.0 – 4.0 scale is not much different when converted to the 0.0 – 4.3 scale, so you can just think of those GPAs that are higher than 4.0 as being roughly equivalent to a GPA near 4.0.


GPAs of applicants to the Master’s Psychology program (clinical and non-clinical) and rejected applicants  

The data are from a single season of graduate program admissions to the master’s and PhD programs in clinical psychology or non-clinical psychology (ie., research). The size of the total pool of applicants that year was somewhere between 120 and 150. The first column shows GPAs of the 12 students who were accepted into the master’s program in clinical psychology that year. The second column of GPAs belong to 12 students who were accepted into the non-clinical master’s program in the same year. The third set of GPAs is from 12 randomly-selected applicants from the same year who were not accepted to either program.

What do you see in these numbers? One thing you should see is that although the average GPA for those who got into the clinical program is nominally higher than the average for those accepted into the non-clinical program, the difference is small and non-significant. But what about the limited sample size? After all, there are only 12 individuals in each group. What if much larger samples collected over several years of graduate admissions continued to have a mean GPA of 3.85 for applicants admitted to the clinical program and 3.75 for applicants admitted to the non-clinical program. Would it not confirm that you really do need higher grades to get into the clinical program? No, it wouldn’t mean that at all. The average GPA is just that – it’s an average.

If we are interested in what sort of GPA was required, it makes more sense to look at the range of the GPAs for those admitted to the two programs. Both ranges are similar. Applicants didn’t need higher grades to get into the clinical psychology program at Concordia University than to get into the non-clinical program, at least not in this particular year. A GPA around 3.30 was sufficient for either program.

Myth #2 is in fact a myth.

Now, look at that third column of GPAs. They represent applicants who applied to either the clinical or non-clinical psychology programs, but were not accepted. The average is slightly lower than for the other two columns, and the lowest end of the range is a bit lower, as well. But the differences are marginal. We can’t reliably distinguish between successful and unsuccessful applicants on the basis of their GPAs! Whether a GPA is 3.5 or 3.8, it is well within the range of GPAs for either the successful or unsuccessful applicants. Several applicants were admitted with a GPA lower than 3.5, and several failed to get in with GPAs much higher than 3.8. By itself, GPA seems to poorly predict the outcome of applications to graduate school in Psychology.

Look again at that third column. Some rejected applicants had very high GPAs. This just goes to show that truly outstanding grades do not guarantee a successful application to grad school. For some readers this means another myth is busted.

Finally, you might be wondering why there are no really low GPAs in the sample of rejected applications; by that I mean no GPAs below 3.0. This is simply because very few people with grades below that level end up applying to graduate school. Most wouldn’t even consider it, as they correctly assume that their grades are too low. Of course, a GPA below some level is likely to correctly indicate that someone should not be in graduate school and they probably wouldn’t make it through certain programs. That level is much lower than 3.5, and it’s probably a little below 3.0 for most graduate programs in psychology.

Students who thought they were unqualified for grad school because their grades are not outstanding should be encouraged by the data. You don’t need an outstanding GPA that’s almost at the top of the scale – you can get into a top-rated graduate program with grades that are very good, which tends to mean equivalent to an average letter-grade of around A- or B+. Importantly, your chances will only be realistic if you have all the other essential elements the admissions committees and prospective graduate supervisors are looking for. It happens all the time. If you haven’t already seen it, check out this previous post about a guy who got into Cambridge University with a GPA of 3.27 (on the 0 – 4.3 scale).

Meanwhile, many students with stellar GPAs mistakenly believe that’s all they need to get in. But, check that assumption against the data shown here; notice the high GPAs among the sample of rejected applicants. Some individuals were passed over in favor of others who had considerably lower grades. Most likely most of the rejected applicants were missing key elements, so despite their outstanding grades, they were not among those applicants deemed most likely to succeed in the program. Just as likely, some of them might have requested the wrong professors to have as their supervisor, without realizing that in almost any graduate program the professor who an applicant requests to have as supervisor will be the one to decide who to accept or reject. There are many reasons why a professor might not be interested in an applicant, and any one of them is sufficient to thwart an application.


MyGradSchool Blog: It all begins

Well here begins a new resource to University and College students seeking information about applying to and surviving grad school. I hope it will also serve as an outlet to discuss higher education issues.

Here’s a bit of my bio: I am a Associate professor at a University in Montreal, Canada. I am a academic advisor as well as a research supervisor of Ph.D. and masters students. I have written a book on getting into grad school successfully, it’s called: Graduate School: Winning Strategies For Getting In With Or Without Excellent Grades. You can check it out at amazonI have been on many selection committees in my department,  and I am a regular contributer to the web site that features advice from experts on the topic of applying to graduate or professional school.

And lastly, I was once a student myself, applying to graduate school with a lot of the same questions that I see students have today when it comes to applying and also surviving grad school. I studied in both Canada and the United States and earned my Ph.D. in 1992.

Here are a few other links that describe a little bit about who I am and what I do:
