All About EVOS

What is EVOS?

EVOS is an optimization program – a computerized algorithm – that determines the best possible schedule for you based on your preferences, the preferences of your classmates, and course availability. The result is the best possible set of Patient Care schedules for your class as a whole.


How does EVOS work?

EVOS matches student course preferences to course availability. You and your classmates’ preferences are reviewed by EVOS simultaneously to determine the best possible schedule for every student. Every student’s preferences are taken into account.


Why EVOS instead of student surveys?

Short answer: Efficiency, time to results, equity, and ability to quantify & evaluate results.

Long answer: Past surveys collected students’ priority clerkship and ranking of sites within that clerkship, and schedules were then created manually. It took months (literally). In addition, which student do we begin with – after all someone had to get scheduled first and someone had to get scheduled last. Schedules were adjusted to be as equitable as possible, of course, but there was no way to know exactly when the best outcome was reached and student preferences maximized. It was a Herculean effort to get schedules out, and impossible to create multiple versions to find the best overall schedule for everyone.

The beauty of EVOS is that it does more than a survey and manual scheduling can. It’s more efficient, faster, considers all students’ preferences simultaneously, and stops when the schedules produced are, as measured quantitatively, the best possible set of schedules.

What won’t EVOS do?

EVOS won’t: Give you everything you preference.

    • What you get (and when and where) depends upon a lot of things, including your classmates’ preferences. If 20 students make their #1 preference the same course at the same site in the same time period, not everyone can be scheduled for it if there’s only availability for 5 students.
    • How specific you are in your preferences makes a difference in how easily EVOS can match you to courses. See Preferencing Strategy [INSERT LINK] for details.
    • Tight course availability in some departments means that EVOS doesn’t have a lot of wiggle room to schedule. Since the goal is uninterrupted progress toward your degree, EVOS may place you at sites and at times you did not preference rather than omitting a required clerkship.

EVOS won’t: Override enrollment maximums (i.e. put more students in a course than there is room for). Departments set enrollment size based on preceptor availability at the time the course is taught, site guidelines, accreditation standards, and educational best practices. The school (and EVOS) honors those decisions.

EVOS won’t: Open back up if you miss the preferencing end date and time. It closes, starts computing, and hangs out a do-not-disturb sign.

EVOS won’t: Read your mind! EVOS will work with whatever you enter, so it’s very important to follow the specific instructions. Translation: READ THE DIRECTIONS! Seriously. Just take a minute to read them.


THE BOTTOM LINE

EVOS will schedule your Patient Care clerkships so that you – and all your classmates – are making unimpeded progress toward your degree, and EVOS will do it via an equitable mathematical process that considers all student preferences simultaneously.
