The McMaster CASPer is required for a complete application to McMaster University’s Undergraduate Medical Education (UGME) program. Because the McMaster CASPer requirement directly affects pre-interview ranking and interview eligibility, applicants must understand how CASPer is used in McMaster’s admissions process and how to prepare strategically.
McMaster uses CASPer in order to assess prospective students for the personal and professional characteristics believed to be important for success and in the program. It is a complement to the other tools that are used for applicant screening, and thus is not the only aspect determining admission, but is heavily considered.

What Is CASPer and Why Do Canadian Medical Schools Use It?
To understand the McMaster CASPer requirement, it is helpful to review what CASPer measures and why Canadian medical schools rely on this assessment. CASPer is a situational judgment test (SJT) where applicants will be given different situations, asked what they would do in these situations, and why they would make those decisions. The CASPer test can take anywhere from 65-85 minutes, with two optional breaks.
CASPer is mainly used in assessing the non-academic skills of the applicants. These core competencies include individual ethics, professionalism, communication, empathy, and judgement of the applicants.
Developed in 2004 at McMaster University, CASPer has soon grown to be one of the most widely used situational judgment tests (SJT) in higher education admissions. This has spread to many parts of the world including the United States, Canada, Australia, and the United Kingdom.
Much like how in American medical schools, where CASPer is utilized as part of a holistic review, the CASPer exam is considered as an important part of the application package. However, it is widely believed that in Canadian medical schools, an exceptionally high CASPer score could help one’s chances of getting an interview from the medical school. For example, in the case of the Max Rady College of Medicine at the University of Manitoba, the CASPer score is considered as 30% of the pre-interview score. In the specific case of McMaster University, CASPer is utilized as part of the pre-interview screening, directly impacting who would receive an interview invite, although the exact percentage is not available.
McMaster University Michael G. DeGroote School of Medicine Overview
McMaster University’s DeGroote School of Medicine contains a program known as the Undergraduate Medical Program, a three year program in which students are exposed to a broad range of human health problems and early exposure to patients, in locations from more remote Northern Canadian to international settings.
McMaster’s unique Problem-Based Learning (PBL) curriculum is part of what makes the school so special. This curriculum, unlike a normal classroom environment, has the students engaging in small groups to discuss real clinical cases through self-directed study, and teaching each other the learning objectives obtained throughout the course.
While many other medical schools employ a teamwork-based approach to their curriculum, McMaster’s PBL curriculum is unique and allows the students a full, immersive experience into the clinical world. It focuses on the integration of knowledge into real-world situations and allows the students to be active problem solvers within each example patient case.
McMaster is also unique in its distributed clinical training under the McMaster Community and Rural Education Program (Mac-CARE). This program allows medical students to not just experience the clinical world in a general urban setting, but also to access the rich diversity of community teaching sites in more rural areas. The Mac-CARE Program gives students the opportunity to learn first hand about community and rural practice.
In addition, the medical school at McMaster University operates at 3 different campuses:
- Hamilton. This is the main campus and therefore has the most students. Its proximity to major clinical sites such as Hamilton General allow the medical students to develop their knowledge, skills, and professional identity within a clinical setting.
- Niagara. This campus is smaller than the Hamilton campus and was opened in 2008 to combat the shortage of physicians, enhance patient care, and improve research and education capacity. Their clinical sites generally collaborate with Niagara Health System in order to help students gain more experience and exposure into the clinical setting.
- Waterloo. This campus is also more regional and smaller with strong collaborations with clinical settings such as the Grand River Hospital and the St. Mary’s General Hospital.
At McMaster University, there is also a strong emphasis placed on professionalism and teamwork. The PBL curriculum itself is strongly interwoven with teamwork where one’s grades are assessed through how one handles themselves and learns in collaborative environments. In addition, the Professional Competencies curriculum is also a key part of the 3 year medical program at McMaster. This curriculum builds essential skills of physicians in a clinical practice such as ethics, communication, self-reflection, teamwork, and more.
Because McMaster is the birthplace of CASPer, it only makes sense that it plays a key role in the admissions philosophy. Due to McMaster’s highly collaborative nature of the curriculum itself, CASPer becomes extremely important in finding students who fit into McMaster’s mission of interpersonal teamwork and professionalism. The non-cognitive traits that CASPer tests for such as ethics, communication, and social problem-solving are essential for the success of any student at the MD program at McMaster.
As such an important part of the application package, it is essential that CASPer is submitted on time. Registration typically opens in May – June and one interested should intend on registering as soon as it opens. Most applicants tend to complete CASPer during the months of August – October and the latest possible dates fall around late October to early November depending on the deadline of the medical school. Check with each school’s specific deadlines to be more exact. Because of McMaster’s emphasis on teamwork, ethics, and communication within problem-based learning, the McMaster CASPer plays a critical role in identifying applicants who will succeed in this collaborative environment.
McMaster Admissions Overview
McMaster’s MD admissions process is highly rigorous.
- Ontario Medical Schools Application Service (OMSAS): The pre-application is submitted through OMSAS and generally opens around July and closes in early October. Note that a minimum of 3.0 on the 4.0 OMSAS scale is required to apply.
- MCAT requirements: Uniquely, for McMaster, only the Critical Analysis and Reasoning Skills (CARS) portion is used and you must score at least a 123 in the CARS section to be able to apply. Please also note that the most recent MCAT score is used, not the highest.
- CASPer requirement: The English version of the Casper (CSP-10211) is required to be completed in order for the application to be considered complete.
What is unique about McMaster’s secondary application is that McMaster has no secondary additional personal essay. Essentially, when one submits their extracurricular details in the OMSAS as part of the Autobiographical Sketch (ABS), that is the extent of what is considered.
After the pre-interview ranking has been determined, approximately 570 applicants are selected for interviews in March or April 2026. This interview process is known as the Multiple Mini-Interview (MMI) where the candidate’s personality, such as their ethical reasoning, communication, empathy, and teamwork is considered.
Applicants invited to the MMI are required to indicate their campus preference by ranking the Hamilton, Niagara Regional, and Waterloo Regional campuses in order (1–3) or selecting no preference. Admission offers are made from a single overall ranked list, without regard to campus preference, and once all 217 seats have been allocated, remaining candidates are assigned to campuses based on their stated preferences and, if necessary, a rank-weighted lottery.
Finally, around 217 students are offered admission with 32 positions for the Waterloo Campus and 32 for the Niagara Campus.
McMaster CASPer Requirement: What Applicants Need to Know
McMaster requires CASPer for all MD applicants. It is extremely important that prospective students complete this requirement as the application will not be considered complete without it.
When selecting the CASPer, prospective students must ensure that they are selecting the correct one. McMaster University requires Casper 2 (CSP-10211) and applicants must take the English version of the test. Additionally, one must select McMaster University as part of the distribution list to ensure that they receive the CASPer score.
CASPer is very integrated within the overall admissions timetable as CASPer helps to decide on which applicants should be invited to be interviewed. It is a key part of the pre-interview ranking system and therefore, those with higher CASPer scores have a higher chance of receiving an interview and thus, a higher chance of receiving an admissions offer.
Most applicants sit for the CASPer exam during the months of July and October, with the final OMSAS due date being October 1st. Therefore, by late October or early November, it is essentially the last possible date to take the CASPer exam. Since interview requests are generally sent out during late January and early February, there must be a CASPer score on file for an interview request to be sent.
How McMaster Uses CASPer Scores in Admissions
The McMaster CASPer is one of the most important non-academic components of the MD admissions process. Unlike some schools that only review CASPer after interviews, the McMaster CASPer requirement is used during pre-interview screening.
What Kind of CASPer Answers Work for McMaster?
It may be helpful to keep McMaster’s mission statement in mind while answering CASPer. The traits that McMaster values are ethical reasoning across the various populations, accountability for one’s actions, professionalism, empathy for patients, clear communication, teamwork, and problem solving for the diverse communities that they serve.
As an assessment that is trying to assess an applicant’s responses to human and complex situations, there are no real “perfect answers” for CASPer. Instead, by focusing on the reasoning behind all the decisions that were made throughout the scenarios as well as reflecting on the actions that were hypothetically taken, an applicant will be able to show their ability in communication, reasoning, and deeper human characteristics.
Strong reasoning, empathy, and professionalism demonstrated on the McMaster CASPer can meaningfully strengthen an applicant’s chances of receiving an interview.
