Whether they’re recent college graduates or retirees, substitute teachers are a diverse bunch with a range of academic specialties and skills. No matter their background, they often arrive at work unsure of exactly who and what they’ll be teaching—but they usually have some tricks up their sleeves to get oriented quickly. Mental Floss spoke to a few subs to get the inside scoop on everything from why they love pregnant teachers to how they spot troublemaker pupils.

1. Morning people get more substitute teaching jobs than night owls.

Substitute teachers must be willing to have a (very) flexible schedule, and it helps if they’re morning people. As early as 5:00 a.m., subs get a phone call—automated or from someone who works in the school’s office—offering them a job for that day. If they accept, they have an hour or two to get out of bed, get ready, and report to work. Some schools now use an email notification system, but early morning phone calls are more effective given the time-sensitive, often unexpected nature of substitute teaching.

2. First impressions are important when it comes to substitute teaching.

According to Kevin, a substitute teacher who works at schools in Southern California, dealing with new groups of students can be challenging. “It’s very hard to establish authority in the classroom. As a newcomer, you’re the foreigner,” he explains.

To immediately establish their authority, some substitute teachers practice speaking with a powerful voice, exhibit confident body language, and shut down any disruptions swiftly and decisively. But no matter how confident a sub is, some students will take advantage of the teacher’s unfamiliarity with the class. “It’s hard to write up a student who you can’t name. In a high school setting, you usually get 30 to 38 students a period for five or six periods. That’s a lot of students who may or may not want to test their bounds that day,” Kevin says.

3. Subs are an eclectic bunch.

Substitute teachers range in age from recent college grads working toward their teaching certification to elderly retired people. But what unites them is a love of teaching. Beverly, a substitute teacher who has taught for over 56 years, says that subbing keeps her sharp and active. “I do it for mental stimulation and because it’s a terrific service. You have to stay stimulated and involved with people,” she says. “I find youngsters to be so forthright and honest. The kids light up my life.”

Besides being a variety of ages, substitute teachers also come from a variety of professions. “You can’t believe how many teachers used to be lawyers but couldn’t stand it,” Beverly says. Everyone from former nurses and flight attendants to chemical engineers have earned their teaching certificates and become subs, bringing their real-world experience into the classroom.

4. There's a reason a substitute teacher's face might look familiar.

In schools in Los Angeles and New York, many struggling actors work as substitute teachers because they can balance teaching gigs with auditions and short-term film shoots. Like actors, subs must be able to speak in front of groups of people, improvise when they don’t have good instructions, and be quick on their feet when something goes wrong.

5. Substitute teachers aren't a fan of school holidays.

Because substitute teachers don’t have a set salary and work one day at a time, many of them face financial uncertainty, especially when holidays roll around. “Holidays can be devastating financially,” Kevin explains. When a school has the whole week of Thanksgiving off, subs don’t see that as a chance to relax. “In reality, a quarter of your paycheck for that month is gone,” Kevin says. “When you have student loans, insurance, etc. to pay, that extra little bit taken off your paycheck may mean you’re just scraping by.”

6. Substitute teachers have tricks to learn names quickly.

Facing a classroom of unfamiliar faces can be daunting, but subs have a few tricks up their sleeves to memorize student names in a flash. While some subs make seating charts as they take attendance, others use mnemonic devices to remember troublemakers’ monikers. Beverly admits that she doesn’t use anything fancy, but because she substitute-teaches math and science classes at the same school, she sees the same kids year after year. “I see the same youngsters out of junior high and into high school, but I do have a seating chart as well. They’re always amazed when I know their names,” she explains.

7. They love pregnant teachers.

Subs seeking job stability hit the jackpot when full-time teachers get pregnant. “At the school I currently work at, there’s a woman who is subbing for the whole semester for a second grade teacher who is out on maternity leave,” says Kyle, a science teacher who worked as a sub before getting a full-time teaching gig. Besides pregnancies, long-term health challenges and injuries can present an opportunity for subs to get a steady gig. Beverly says she once took over for an entire semester because of another teacher’s broken hip.

8. Some substitute teachers are quite familiar with busywork.

Novelist Nicholson Baker, who wrote about his experience going undercover as a substitute teacher at six schools, describes the astonishingly large amount of busywork that subs must assign students. “I passed [work sheets] out by the thousands,” he noted in The New York Times.

While Baker laments the “fluff knowledge” and vocabulary lists that subs are expected to force students to memorize and regurgitate, some subs do teach lesson plans. Kyle, who has a math and science background, explains that some teachers felt comfortable with him teaching the lesson plan so the students wouldn’t fall behind. “I’d teach it and assign homework accordingly for what we covered in class,” he says. But he admits that for middle school or non-science classes, he would sometimes simply be given a video to show the kids, or a work sheet or quiz to pass out.

9. The reputation of a substitute teacher can precede them.

Once a sub has taught at the same school a few times, they can develop a reputation—good or bad—among students. “When I first started subbing, I was 23 or 24, so I wasn’t much older than these kids—especially the seniors—and I think they saw me more as a peer than an authority figure,” Kyle explains. “I thought if I kept a light and fun atmosphere, kids would show their appreciation with respect. But that’s not how kids’ minds work. If you give a little, they’ll want more. So I became stricter and sterner as I went on,” he adds.

10. Substitute teachers can often spot troublemakers fast.

Although it might seem obvious which students are talking out of turn or giving the sub a hard time, substitute teachers have another way to quickly identify any mischievous students. “Usually, if a teacher has a really outrageous student, they’ll leave a note of warning for the sub. Sometimes the teacher will also leave a list of who the helpful students are,” Beverly says.

11. Substitute teachers may deal with inappropriate student behavior.

Kyle says that due to his young age and easygoing nature, some students tried to push the boundaries and act inappropriately with him: “[Students] would talk about or say things in front of me that I know they would never say in front of a teacher. I was once asked to party with some of the kids. Girls would try and flirt with me.” While male students typically tried to talk to him about basketball, female students frequently asked him if he had a girlfriend. “I would lose control of classrooms sometimes. Kids would get very wild, and sometimes would say inappropriate or abusive things to other students without fear of discipline,” he admits.

12. Substitute teachers are honored on a special day in November.

The National Education Association established the annual Substitute Educators Day on the third Friday in November to honor subs around the country. Besides bringing awareness to the work that substitute teachers do, Substitute Educators Day supports subs in trying to get health benefits, professional development, and fair wages.

13. Substitute teachers can make lasting impressions on their students.

Although most subs don’t see the same kids day after day, they can have a meaningful impact upon their students’ lives. “As an outsider, especially a younger teacher, students will often listen to you as someone who recently was in their shoes. Sometimes you talk to them one-on-one and give them a new perspective on why they should care about their schoolwork,” Kevin says.

And some students listen to their sub’s advice on studying and planning for the future. According to Kevin, students have approached him as he walked down the halls to thank him for encouraging them to get better grades.

“These experiences are few and far between, but it’s crazy to think that even these small talks with students can actually have a lasting impression,” he says.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

Five rooms of one's own.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

10 Secrets of Epidemiologists

Unless you know an epidemiologist or are one yourself, those “disease detectives” might not have occupied a very large portion of your brain. Last year, that is. Now, with the coronavirus pandemic at the top of mind—and at the top of so many headlines—there’s a good chance you’re at least aware that epidemiologists study diseases.

To be more specific, the Centers for Disease Control and Prevention (CDC) defines epidemiology as “the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems.” So what exactly does this mean? Mental Floss spoke with a few epidemiologists to shed light on what they do, how they do it, and which germ-friendly foods they avoid at the buffet.

1. People often mistake epidemiologists for skin doctors.

Since the word epidemiologist sounds like it might have something to do with epidermis (the outer layer of skin), people often think epidemiology is some offshoot of dermatology. At least, until the coronavirus pandemic.

“Prior to that, no one knew what I did. Everyone was like ‘Oh you’re an epidemiologist—do you work with skin?’” Sarah Perramant, an epidemiologist at the Passaic County Department of Health Services in New Jersey, tells Mental Floss. “I would be rich if I had a dollar for every time I got asked if I work with dermatologists.”

2. Epidemiologists don’t discover a new disease every day.

Though some epidemiologists do look for unknown diseases—certain zoonotic epidemiologists, for example, surveil wildlife for animal pathogens that might jump to humans—most are dealing with diseases that we’re already familiar with. So what do they do every day? It varies … a lot.

Epidemiologists who work at academic or research institutions undertake research projects that help determine how a disease spreads, which behaviors put you at risk for it, and other unknowns about anything from common colds to cancer. But it’s not just about devising experiments and studying patient data.

“I like to tell my friends and family that my job is about four different jobs in one,” Dr. Lauren McCullough, an assistant professor in the department of epidemiology at Emory University’s Rollins School of Public Health, tells Mental Floss.

Writing, she says, is “the most important part.” It includes requesting grants, devising lectures and assignments, grading her students’ work, writing about her research, and more. She also sits on admissions committees, reviews other epidemiologists’ studies, and oversees the many people—project managers, data analysts, technicians, trainees, etc.—working on her own research projects.

Those who work in the public health sphere are often monitoring local outbreaks of diseases like the flu, Lyme disease, salmonellosis, measles, and more. If you test positive for a nationally notifiable disease (any of about 120 diseases that could cause a public health issue), the CDC or your state health department sends your electronic lab report to the epidemiologist in your area, who’s responsible for contacting you, finding out how you got sick, and telling local officials what steps to take in order to prevent it from causing an outbreak.

3. Epidemiologists have to make some uncomfortable phone calls.

Epidemiologists sometimes have to ask pretty personal questions about drug use and sexual activity when trying to figure out how someone got infected, and not everyone is happy to answer them. “I’ve gotten hung up on many a time,” Dr. Krys Johnson, an assistant professor in Temple University’s department of epidemiology and biostatistics, tells Mental Floss.

Some simply aren’t willing to accept that they might have been exposed to a disease without knowing it. After several employees at a certain company tested positive for COVID-19, for example, Perramant started calling the rest of the workers to tell them to go into quarantine; this way, she could prevent sick people who weren't yet showing symptoms from spreading the disease without knowing it. But not everybody was open to her advice. “They would just swear up and down, ‘I haven’t been in touch with anybody who’s positive, please don’t call me again,’” Perramant says.

But there are plenty of cooperative people, too, especially victims of foodborne or diarrheal illnesses. “They really want to know where they got sick because they’re so miserable that they never, ever want to deal with that again,” Johnson explains. Parents of sick kids are also generally forthcoming, since they want to keep their kids healthy in the future. And then there are those who don’t have any problem spilling their secrets to a stranger.

“There was one woman who was very memorable,” Johnson says. “I called her about her Hepatitis C, and she was like, ‘Oh, honey, I did drugs back in the ’80s. That’s where I got my Hepatitis C. I pop positive every time!’”

4. Epidemiologists deal with a lot of rejection.

Public health epidemiologists have to learn to just shrug off all the rude tones and dial tones, and epidemiologists in academic settings need thick skin for different reasons.

“There’s just a lot of rejection,” McCullough says. “‘That idea isn’t good enough; this paper isn’t good enough; you’re not good enough.’ That is just a resounding thing. There’s a high bar for science; there’s a high bar for federal funding; and it takes a lot to cross that bar. So in the academic setting at these top-tier institutions, you really just have to have a thick skin.”

5. Just because epidemiologists' guidelines change doesn't mean they're wrong.

Sometimes, McCullough explains, the story of a disease can change over the course of one study. When you look at the first 100 people in a 10,000-person study, you’ll see one story emerge. By the time you’ve seen 1000 people, that story looks different. And after you’ve seen the data from all 10,000 people, the original story might not be accurate at all.

Usually, epidemiologists can complete the whole study of a disease and draw conclusions without the world clamoring for half-baked answers. But with a brand-new, highly infectious disease like COVID-19, epidemiologists don’t have that luxury. As they’ve learned more about how the pathogens spread, how long they can survive on surfaces, and other factors, they’ve changed their recommendations for safety precautions. Everyone else in the world of epidemiology expected this to happen, but the general public did not.

“If we say something this week that contradicts what we said last week, it’s not that we were wrong,” Johnson says. “It’s that we learned something between those two time points.”

6. Being an epidemiologist would be easier if people kept better track of their behavior.

Often, people omit vital information about how they got exposed to an illness because they just don’t remember all the details. You could easily recall devouring a few slices of the decadent chocolate cake your mom baked for your birthday last Friday, but you might not be able to name every bite of food you ate on a random Thursday three weeks ago.

“People aren’t telling us the whole truth, but it’s not that they’re being intentionally obtuse,” Johnson explains. “With recall bias, unless there’s a reason for us to really remember, we’re not going to remember everything we actually ate.”

This has made it especially difficult to trace an aerosolized disease like COVID-19.

“All my friends going into the Fourth of July were like, ‘Should we have a get-together?’” Perramant says. “And I said, ‘You can have people over, but you better take an attendance list. You better have a little spreadsheet on Google Drive that has every person’s name and their phone number, so that when one person tests positive and gets sick this week, when I call you, you will be able to give me that information like that.’”

7. Epidemiologists have reason to be wary of buffets, cruise ships, mayonnaise, and cubed ham.

Infectious disease epidemiologists may have accepted that germs are a part of life, but they also know where those germs like to congregate.

“I don’t go to buffets, I have never been on a cruise ship and I don’t intend to, I’m super conscientious when I fly,” Johnson says. “And I’m really aware of whenever mayonnaise-based things are put out at family functions. If you’re ever at a potluck and people come down sick, the first thing people say [they ate] is potato salad or egg salad, because mayonnaise can spoil so quickly.”

“[Cubed ham] is one particular microbe’s very favorite thing to multiply on, so if you’re gonna have ham, make it a whole ham,” she says.

8. Teaching people is a really rewarding part of being an epidemiologist.

In addition to actually leading lectures in the classroom, academic epidemiologists also work extremely closely with their students on research projects; McCullough estimates that she’s in contact with hers at least once a day when they’re collaborating on a study.

“To work with someone so closely, and to watch them progress as a scientist and as a person, and then to have to let them go and send them out into the world, I find that very rewarding,” McCullough says of her trainees. “As a scientist in an academic institution, there’s not a whole lot of immediate gratification. Our papers get rejected, our grants don’t get funded, but the trainees are always a source of immediate gratification for me, so I hold them close to my heart.”

Epidemiologists in other spheres have teaching opportunities, too. When a community experiences a disease outbreak, public health epidemiologists like Perramant are responsible for helping the general public understand what they can do to prevent the spread.

“I like to teach kids about infectious disease and infection prevention for what’s relevant to them. We’ve had a couple of large outbreaks at summer camps, and last summer I put together a training for camp counselors,” Perramant says. “That’s always a part of my job that I really love.”

9. Epidemiologists have a unique understanding of racial disparities.

At this point, it's exceptionally clear that COVID-19 is disproportionately affecting people of color in the U.S. They're more likely to be exposed to it, they have less access to testing, and the preexisting conditions that place them at a higher risk can be the result of systemic racism. When these trends started to become apparent, McCullough got flooded with phone calls asking why. Her answer? This isn’t new. As she’s seen in her work as a breast cancer researcher, Black women are more likely to die of that disease than their white counterparts, and similar health disparities exist across the board.

McCullough explains that the general public is finally realizing what epidemiologists already knew: That poor disease outcomes in minority, low-income, and rural populations aren’t because of anything those people are doing on an individual level. Instead, it’s a result of systemic issues that keep them from leading financially comfortable, healthy lifestyles with access to healthcare and other resources.

“It’s not just COVID—it’s almost every single chronic and infection ailment that’s out there,” McCullough explains. “So this is a real opportunity for people to step back and take an assessment of where we are in terms of our healthcare system, and what we’re doing so that everybody has equitable outcomes. Because people shouldn’t die just because they live in a rural area, or just because they’re poor, or just because they’re Black or Hispanic.”

10. They've had to deal with a lot of “armchair epidemiologists” lately.

Until this year, epidemiologists had to suffer through people mistaking them for dermatologists. Now, during the coronavirus pandemic, people finally know at least a little about their jobs. In fact, people are so confident in their newfound epidemiological knowledge that many are fancying themselves experts on the subject.

“At the beginning of 2020, there were like 500 epidemiologists, and now there are about 5 million. Everybody thinks they’re an epidemiologist,” McCullough says. “There’s a science to it, and it’s a science that requires training. We went to school for a really long time to be doctorally trained epidemiologists.”

It’s not just about advanced degrees, either. Beyond that, you need years of firsthand experience to grasp all the nuances of understanding methods, interpreting data, translating your findings into recommendations for the general public, and so much more. In short, you can’t just decide you’re an epidemiologist.

Perramant has her own analogy for the recent influx of self-proclaimed epidemiologists: “It’s like armchair psychology. Poolside epidemiology now is a thing.”
