Innovation vs. Inertia: Examining Course Schedule Characteristics

Ask most registrars how their institution structures its course schedule, and they can probably answer quickly. Tuesday/Thursday is popular, time blocks are established, and in-person lecture remains the backbone of course delivery. What's harder to answer is whether those patterns reflect intentional design or an unexamined habit.

A joint survey by AACRAO and Coursedog of 340 institutions examines how institutions across higher education structure their schedule offerings across days, time blocks, and delivery modalities. These patterns matter because when schedules are built around tradition rather than student need, the cost rarely appears in the schedule itself. It shows up in delayed progress, extended timelines, and students who quietly stop out.

Are Weekend Classes an Untapped Opportunity or Intentional Exception?

When it comes to the days classes are offered, higher education follows a recognizable pattern. Tuesday, Wednesday, and Thursday see classes scheduled at 100% of surveyed institutions. Monday sits at 99% and Friday at 95%, making the traditional weekday window nearly universal across the field. That consistency reflects decades of established practice, and many institutions rarely examine it.

Weekend scheduling breaks from that uniformity. Just 29% of institutions offer Saturday classes and 9% offer Sunday classes, and among those that do, more than half apply a different set of factors to determine when weekend courses are scheduled. Those offerings are typically reserved for cohort-based programs or scheduled only by exception. With non-traditional students now making up the largest share of the student population, a weekday-only framework may not reflect the scheduling realities of the students institutions actually serve.

Limited Class Combinations Leave Little Room for Experimentation

The Tuesday/Thursday combination is the most widely used day pairing in undergraduate scheduling, selected by 95% of institutions and identified as the most frequently used combination by 51% of respondents. Monday/Wednesday/Friday and Monday/Wednesday round out the top three.

What stands out is how little room remains outside those structures. The Friday, Saturday, and/or Sunday combination is used by just 4% of institutions, making it the least common option. Yet 33% of respondents selected "another combination of days not described here," suggesting that while the dominant patterns are well established, a meaningful share of institutions are operating outside the standard framework.

Strong Emphasis on Prime Time Hours Restricts Students and Space

Most undergraduate schedules are built around a window of time that assumes students are free during the day. Established time blocks now serve as the standard for undergraduate scheduling, with 89% of institutions reporting their use, up from 82% in a 2016 survey.

The most common start times fall between the mid-morning to early afternoon window, with classes most frequently beginning between the prime time hours 10:00 a.m. and 1:59 p.m. Only 17% of institutions schedule classes after 8:00 p.m., and classes before 7:00 a.m. are offered at just 4%.

For students who work full time, manage caregiving responsibilities, or commute long distances, a midday-heavy schedule can create barriers. When the majority of sections are built around a window that assumes daytime availability, students whose lives don't fit that assumption are left with fewer options, longer paths to completion, or both. The concentration of classes in primetime hours also carries an institutional cost. Classrooms sit empty in the early morning, later afternoon, and evening hours, representing space that could be put to better use. Institutions that redistribute classes more evenly across the day have an opportunity to improve both student access and space utilization at the same time.

Online Classes are Now an Expectation, Not a Differentiator

Before COVID-19, most institutions operated within a narrow set of course delivery options. The pandemic changed that quickly and, for many institutions, permanently. In-person lecture remains the backbone of undergraduate delivery and is used by all institutions that are not exclusively online. But the data reveals how far the modality landscape has expanded beyond that single default. In-person hybrid is now offered by 81% of institutions and online asynchronous lecture by 79%, suggesting that blended and flexible delivery options have moved from exception to expectation.

Across surveyed institutions, 147 different combinations of modalities are currently in use, and 8% of institutions schedule undergraduate classes across all 13 modalities. The full list extends well beyond lecture and hybrid formats to include practicums, independent study, HyFlex, on-campus studio and open-lab time, and online lab formats in both synchronous and asynchronous versions. That level of variation reflects both the opportunity and the complexity that came with the pandemic's forced expansion of delivery options. For students, a wider modality mix can expand access and increase flexibility.
