How the CASPer® Assessment for Medical School is Scored

CASPer® assessment

Understanding how CASPer® is assessment and how CASPer® is scored may help you create your CASPer® preparation plan.

Usually, CASPer® assessors undergo an orientation that is intended to guide them on the logistical aspects of marking the exams such as logging in securely, having the right software to support the marking process and so on. They are also trained on the criteria they need to apply when assessing each response from the student. Training on these basic criteria is intended to minimize subjectivity during marking.

CASPer® assessors are typically medical students, medical residents or faculty with an interested in admissions review. At times, non-medical faculty are involved in the scoring process to add another element of objectively and diversity of assessment.

During scoring, the personal identifiers of the student are not available to the assessor. This is to eliminate bias. Also, each applicant’s CASPer® exam goes through 12 distinct assessors, in order to increase the inter-observer reliability of the test. Remember it is much easier for one assessor to fail you as compared to 12 who have twelve distinct observations and opinions. This is important because the assessors are not given an answer key and rely on their training and judgement to score your CASPer® exam.

Each of your responses will be judged based on the criteria that the assessors have been trained on. It is important to note that application of the criteria will vary depending on the scenario you are responding to. For instance, you might come across a question such as this:

You are a resident at an outpatient clinic when you come across a patient diagnosed with ovarian cancer that requires surgical intervention. While discussing details of the surgery, you explain that open and laparscopic oophorectomy are both possible options in her case.

Question 1: How would you go about ensuring that the consent provided by this patient is informed?

In the course of your discussions, the patient tells you that they would like to give chemotherapy a chance before/instead of undergoing surgery.

Question 2: How would you respond to this decision?

Without going into the medical terms which are usually meant to stress you a bit, the question here is clearly one of informed consent and patient autonomy and other ethical areas. If you are able to demonstrate that you have recognized the several dimensions that come into play in this scenario, you will get a better grade from your assessor.

The grading of CASPer® responses use a Likert-style scale that is numerical that runs from 1 to 9 with 1 being unsatisfactory and 9 being superb.

If in a particular scenario you are unable to answer all questions, you will still be graded strongly as long as the answer you provided to the question you are able to answer is well thought out and mature.

CASPer® assessors are required or expected to flag a response if it is considered a ‘dangerous, unethical, unprofessional, and potentially harmful approach to the scenario at hand’.

Success Stories

Jess B (2018)

Accepted to UWO Medicine (MD/PhD)

I enrolled with Med Applications one month before my first interview. I had been preparing for interviews by reading books and discussing questions with friends and family, but I was still nervous and didn’t really know what to expect. I felt so much more comfortable after my session with MedApplications. My instructor was very knowledgeable and catered the session to what I needed work on (as I had both panel and MMI interviews, this was particularly beneficial). It was very useful to cover topics with someone who knew what to expect from an interview and could comment on the quality of my answers. All together the experience was extremely helpful and very reassuring; it significantly calmed my nerves during my interviews. There weren’t any questions I was surprised by in my interviews. I would definitely recommend a session for future students.

Roxana M(2018)

McGill Medicine (MD)

“MedApplications helped me with both my essay preparation which brought me to the big interview and with interview preparation. MedApplication's services provided me with not only an insight of how to tailor an application to bring out the best of my ability but it also gave me the confidence I needed to survive the MMIs.

K. Y.2018

O uf T, UBC, McMaster

"I used MedApplications mock interview service because I wanted to practice and receive feedback from a current medical student. I found the mock interview helpful in identifying weaknesses in my answers and improving on them to make them stand out. I would recommend MedApplications to anyone who wants extra preparation to gain confidence for medical school interviews."


U of A

"I went into my first MedApplications session without a clue about what MMI's were or how to prepare for them. After meeting and practising with Eric and Kent, however, I learned all of the tips and skills I needed to ace the interview. They were incredibly knowledgeable and encouraging and their help gave me that extra boost of confidence on interview day. Thanks MedApplications!"

Hana W(2018)

University of Ottawa Medicine

“I was accepted at Ottawa which was my ideal school and my only interview. Josh was absolutely wonderful and definitely part of my success! He was very helpful throughout the entire process 🙂


Mother of a High School student for a Pre-Med program

“Hi MedApplications, just to let you know that Isabelle got an offer from University of London St. George’s College. The competition this year was quite challenging. We would like to thank you and Sarah for your contribution to this achievement. Your services are excellent. Please count us among satisfied clients.”

Matthew L. (Class of 2018)

McMaster University Medicine

"I used the MedApplications seminar and mock interview services before I had my interviews at Queen's and McMaster medical schools, and I couldn't be happier with my decision. Their seminars were incredibly helpful in providing information about the interview process and ways to truly emphasize your best qualities in an interview. Their mock interview session was great as well as it gave me an opportunity to practice my interviewing style with a current medical student! If you are looking for a way to prepare for an interview as important as the ones for medical school, I would definitely recommend MedApplications."
