Three (Unexpected) Things We’ve Learned from Substitute Data

What questions do you have about substitute teaching in your district? Curious about where subs choose to work? When demand for subs peaks? How frequently subs work? Chances are many of those questions can be answered by digging into the data you are already have available through your substitute management system. 

In the last few months we have been surprised by just how much you can learn through analyzing substitute data and how infrequently districts are digging into this rich data source.

Here are a just three critical insights we have uncovered, we hope they pique your curiosity and get you thinking about what you might learn from your own data:

1. No Monday/Friday Peak: Every district we have sat down with shares the assumption that it is harder to cover teacher absence on Mondays and Fridays, mostly because demand is higher, with more teachers absent. It makes intuitive sense, because who doesn’t like a three day weekend? While it is possible that HR and school offices are working harder on these days, the data we’ve gathered at Substantial suggest that both demand and coverage is fairly consistent through the week, with no big spikes on Mondays or Fridays. If we see slightly lower coverage on a Friday, it’s usually because of supply—not demand—as fewer subs are choosing to work.

2. Different Districts Have Different Pools: In one district, 74% of substitutes are over the age of 50 and most work around one day a week. This seems to back up the anecdotal evidence that retired teachers dominate their pool. In another district, the vast majority of subs are women in their 30’s and 40’s who work at a specific school site. This suggests a pool made largely of parents who have a connection to a specific school. Understanding your substitute pool is critical because the needs and motivations will be different. By knowing your pool, you can develop meaningful support and tackle supply challenges more effectively.

3. Coverage Varies Dramatically: Within a single district substitute coverage rates can vary dramatically among school sites. If districts are looking at data, it’s often in the aggregate, and these nuances can be obscured. For example, in a district with an average of 80% teacher absences covered, one school may be at 99%, and another is languishing at 54%. What’s intriguing is that it isn’t always the schools you expect. We’re learning a lot by focusing on the schools that surprise us and challenge our assumptions about where subs want to go.

From our early analysis, one thing is very clear—understanding the root cause of substitute system challenges is critical to ensure you’re designing strategies that will work for your district and your subs.

Bringing a Little Kindness and Innovation to Teacher Absence

Yesterday’s Washington Post included an eye catching headline: one in four teachers miss 10 or more days of school, earning the label “chronically absent.” Although the article was careful to present a balanced view, the comments section quickly devolved into the predictable argument about valuing vs vilifying teachers. Notably missing from the article—and virtually all conversation of teacher absence and its impact on students—is an examination of how to improve the experience students have when their teacher is out. Life happens and teachers will be absent. In fact, when I think about my son’s teachers, I want and hope that they feel supported as they deal with the curveballs life throws at them—from bouts of mental illness (like the teacher interviewed in the article who was struggling with anxiety) to caring for an ailing family member or having a baby.  

Rather than just focusing on reducing absences, what if we also thought about how to create a supportive experience for students when their teacher is out? Substitute teaching has been largely the same for decades. We know that the current design isn’t working well—the statistics around how much teacher absences impact students demonstrates that time spent with substitutes isn’t cutting it. But what is possible? What if we let go of what we assume substitute teaching has to be and redesigned it from the ground up? Could we create something that supported teachers and actually enhanced students’ learning experiences? Asking this question is more generative and invites more creativity than focusing solely on reducing teacher absence. It’s also something every school and district can work on today.

Intrigued? Here are some ideas about how to get started:

  • Confront Your Assumptions: The mental model for what happens when a teacher is absent has been ingrained in each of us since childhood. Our assumptions can limit our creativity and willingness to experiment with new models. I invite you to spend 10 minutes cataloguing your assumptions, such as “substitute teachers are on call employees.” Set a timer and write everything that comes to mind. If you have 10 more minutes, pick one or two of your assumptions to challenge. Ask yourself, what would happen if this assumption weren’t true? What might be possible? Brainstorm your crazy ideas and see what happens.
  • Pilot Something Different on PD Days: Pick an upcoming PD day and pilot a new model for what happens when the teacher is out of the classroom. Invite your teachers to brainstorm different possibilities and pick a few to pilot. Maybe you could do an inside-out field trip where you bring an expert to school for a day. If the first grade teachers are out, could this be a day for first graders to spend more time with their fourth grade buddies? Challenge your assumptions about what’s possible.
  • Create a Design Challenge with Students: Students are great at questioning assumptions and thinking outside the box. Invite them to bring that creativity and think about what should happen when their teacher is absent. Stanford’s K12 Design Lab has great resources for facilitating design challenges with students.
