Understanding Acuity Insights: Casper, Duet, Snapshot


So you know about Casper, but what’s with Acuity Insights? That’s right, your road to medical school acceptance just got even longer. Read on to learn more about Acuity Insights (previously Altus Suite) and its components, including Casper, Snapshot, and Duet.

When did Casper change to Acuity Insights? What’s included, and how do you know whether or not you need to complete these additional application components? We’ll answer these questions and more.


From the Casper Test to Altus Suite to Acuity Insights

Casper stands for “Computer-Based Assessment for Sampling Personal Characteristics.” It’s a computer-based test created to evaluate your people skills, professionalism, empathy, and ethics. Casper measures who you are beyond your hard skills and exceptional grades.

Casper was developed in 2010 by Harold Reiter and Kelly Dore at McMaster University’s Program for Educational Research and Development (PERD) in Canada. It was created due to a perceived lack in the conventional medical school application’s ability to communicate an applicant’s interpersonal communication skills and empathy to an admissions committee.

There’s a lot more to being a doctor than exceptional knowledge of science. Doctors must also be able to clearly and effectively communicate with their patients, and this is something that’s difficult to measure based on someone’s MCAT score and personal statement.

Beginning with the 2022 application cycle, Casper changed to Altus Suite, with the URL changing from “takecasper.com” to “takealtus.com.”

Beginning with the 2023 cycle, Casper changed to Acuity Insights.

Casper is only one component of Acuity Insights.

Understanding Acuity Insights: Casper, Snapshot, and Duet

Acuity Insights is a multi-part assessment designed to evaluate a prospective medical student’s people skills and bedside manner. Applicants now have multiple opportunities to demonstrate their personal and professional skills in both verbal and written content.

Casper is a 90-110 minute situational judgment test that evaluates 10 non-academic attributes in applicants, such as collaboration, empathy, ethics, and professionalism.

Snapshot is a short (about 10 minutes), one-way video interview that further assesses an applicant’s people skills by asking them why they want to pursue medicine and become a doctor. Note: Snapshot will not be required for any programs in the 2023-2024 cycle.

Duet is a value-alignment assessment that compares what an applicant values most in a program to what the programs have to offer. Duet only applies to applicants to US medical schools and graduate medical programs.

Below we’ll answer common questions about each of the different Acuity Insights components—Casper, Snapshot, and Duet.


Common Questions About Casper

How is the Casper Test Scored?

Casper presents you with 14 different scenarios. Each scenario is scored by a unique rater, which means that no two sections of your test will be scored by the same person. Raters are not provided with any of your personal information whatsoever.

Casper isn’t made up of right or wrong answers. Raters are given general information about the central concepts and ideas that are essential to the section, but they aren’t given any kind of answer key.

Each scenario has 2-3 questions, but sections are scored based on your overall performance. If you miss the last question, but your previous answers are comprehensive, you may not incur a penalty.

Read our guide for a complete overview of How the Casper Test is Scored.

How Long is the Casper Test?

The Casper test takes 90-110 minutes to complete, including two short breaks. There is a video response section and a typed response section with a total of 14 scenarios. You will be presented with either a word-based or video-based scenario followed by open-ended questions.

Where Do I Take the Casper Test?

The Casper test is taken online, so you can take it from home or from any place that’s quiet and comfortable. All you need to take the test is a computer, a reliable internet connection, up-to-date browsers, a working webcam, and a working microphone.

How Many Times Can You Take a Casper Test?

You can only take the Casper once per application cycle. If your medical school application is unsuccessful, you will need to take the Casper again if you choose to reapply.

Common Questions About Duet

Does it Cost More to Complete Duet?

The fee to take Casper is $85 USD, which includes distribution of results to 8 programs. An additional $15 USD is charged for each additional program you need to send your results to. The fees you pay when you reserve your Casper test cover all applicable parts, including Snapshot and Duet.

When is Duet Due?

Individual programs determine their Acuity Insights requirements for their admissions process. It is recommended that you complete Duet within two weeks (14 days) of taking your Casper test, as this will ensure all of your Acuity Insights components can be viewed together by the programs you’re applying to.

If individual program requirements change, you will still be able to complete Duet anytime before your earliest program distribution deadline.

How Do I Prepare for Duet?

Duet is a measure of your own personal values and preferences, so there is no practice component. Read the instructions, the characteristics, and their descriptions carefully before moving on to the comparison pages. Once on the comparison pages, choose what feels right to you, as there is no right or wrong answer.

Before completing your Duet assessment, take some additional time to assess what you are looking for in a medical school and what matters most to you. Unsure? What locations do you prefer? How much are tuition and fees for each school you’re considering? What financial aid opportunities are available? What are your special interests in medicine? Do you align with the school’s mission and values?

Common Questions About Snapshot

NOTE: Snapshot will no longer be required for any programs in the 2023/2024 cycle. Select programs will still require Snapshot for the 2022/2023 cycle. Check the dates and fees page on Acuity Insights for requirement details.

When is Snapshot Due?

It is recommended that you complete Snapshot within two weeks (14 days) of taking your Casper test, as this will ensure all of your components can be viewed together by the programs you’re applying to.

If individual program requirements change, you will still be able to complete Snapshot anytime before your earliest program distribution deadline.

Where Does the Snapshot Interview Take Place?

Just like the Casper test, you will participate in your Snapshot interview virtually. This means it’s up to you to ensure your technology is up-to-date and you have a reliable internet connection. Choose a quiet room free from distractions where you won’t be interrupted.

How Long is the Snapshot Interview Process?

The Snapshot interview should take about 10 minutes to complete. Snapshot is made up of three interview-style questions, and you are allotted two minutes to respond to each.

You will also be asked to complete a mandatory practice session that will help you prepare for the real interview. After practicing, you can begin your Snapshot interview, though you can practice as many times as you like.

Before the recording begins for the real thing, you’ll be able to read the first question and have 30 seconds to reflect on your response. You have up to two minutes to record your response, but you can stop the timer if you finish early. Responses are automatically saved, so you cannot re-record yourself.

How Many Snapshot Interviews Do I Need to Record?

You will usually only need to complete one Snapshot interview, which will then be sent to all of the programs on your distribution list. The exception to this is if you are applying to both English and French programs. In that case, you will need to record one Snapshot in English and one in French.

Does it Cost More to Complete Snapshot?

The fee to take Casper is $85 USD, which includes distribution of results to 8 programs. An additional $15 USD is charged for each additional program you need to send your results to. The fees you pay when you reserve your Casper test cover all applicable parts, including Snapshot and Duet.

What Will I Be Asked During the Snapshot Interview?

Expect the questions to be similar to the other professional interviews you are preparing for, such as questions about why you’re applying to medical school, your strengths and weaknesses, and tell me more about yourself.

For example, “What is an obstacle you have faced, and how did you get through it?” Or, “Tell us about someone you admire and why.”

How Do I Prepare for the Snapshot Interview?

Ensure you take the interview somewhere quiet and test all of your tech in advance. Make sure your background is clean, and you are dressed professionally, wearing neutral colors like you would for an in-person interview.

Prepare answers to common interview questions like the ones mentioned above and practice answering them alone in front of a mirror, in front of friends and family members you trust, and in mock interviews.

It’s also important to warm up your face and vocals before the Snapshot interview. Tripping over your words will make you appear nervous, so quickly repeat phrases like “red leather, yellow leather,” and “the tip of the tongue, the teeth, and the lips.” Focus on really enunciating each and every word and exaggerating the movements of your mouth.

This kind of practice will loosen up your mouth and help you to speak articulately and confidently during the interview.

Like an in-person interview, you will only have one chance to answer each interview question, which means you need to be thoroughly prepared and practiced before beginning your Snapshot interview. After your two minutes are up, your live-recorded interview questions are automatically submitted, which means you need to practice being succinct when answering common questions.

While practicing, use a timer to get a feel for how long you’ll have for each question. Don’t memorize your answer so that you’re not tripped up by a slightly different question, but do practice hitting specific key points within each of your answers.

If you are having difficulties with confidence, body language, answering succinctly, or getting your point across clearly, we recommend participating in mock interviews, which will provide an honest assessment of where you’re at and what you need to work on.
