Teacher Billie Lane’s portable is a world apart from other classrooms at her school.
She’s filled the space with toys from across the universe: Star Trek, Star Wars, Marvel, Transformers and Godzilla. Lane’s World, her students named it — an homage to the faux public-access TV hit.
The modular classroom at Kalles Junior High in Puyallup, Washington is her home. She’s taught in the box for 16 years.
And she takes care of it. But not every portable classroom is like hers.
“Some of them smell really bad,” she says. “Some of them, the lighting is really bad. It’s dark. It’s dank. And when it’s that kind of an atmosphere, it sets a tone for your meetings or for your classroom. It doesn’t feel very welcoming. It’s not a good place to be.”
Watch a video report:
The Puyallup School District where she teaches has 205 such boxes. They form 20 percent of the district’s classroom space. They hold more than 4,000 students — so many that a new high school, a new middle school and two elementary schools wouldn’t provide enough classroom space for them all.
The prefabricated structures come cheap and fast. They offer a lifeline for districts with more students than building capacity, a problem recent projections show will worsen in coming years. An estimated 385,000 portables are in use at schools across the country. But portable classrooms more often than not become permanent fixtures. The largest districts in Oregon and Washington now have thousands of them and a majority are more than 20 years old, data collected by InvestigateWest and EarthFix show.
Those short-term fixes can lead to chronic problems. They burden schools with high energy costs and frequent maintenance needs. They expose students and teachers to mold and mildew, poor ventilation and the potential for volatile gases from cheap building materials.
Shaylee Adams is one of Lane’s students. The 14-year-old has been in portables that were too hot, too cold, isolated and vulnerable during a school lockdown and ventilated so poorly they made her sick. She has some advice for students not as seasoned at learning inside the box:
“Bring water. Bring a jacket. Be prepared for loud noises. Basically, be prepared to be distracted a lot.”
Listen to an audio report:
Rudy Fyles has watched Puyallup’s rural identity vanish as suburban sprawl has gobbled up its farmlands and open spaces. The number of students in the district has doubled, now more than 29,000 by the latest census count, since Fyles entered the district 18 years ago.
That shift left Fyles, the district’s chief operations officer, in a dilemma familiar to many school administrators — for just one-third of the up-front costs of new construction, portables were an affordable way to add classrooms.
But over time, they’ve come to cost twice as much as brick-and-mortar school rooms while offering much less than traditional buildings.
Tear open a portable and often you will find cheap plywood, particle board, insulating foams and glues — the modular industry often builds to order, and school budgets are tight. Construct four walls and a roof from that, expose it to the elements for a decade longer than intended and watch your energy and maintenance costs soar. (Story continues below.)

Portables are often charged residential electricity rates because they are separate from the rest of the school. Those can be 25 to 30 percent higher than the rest of the school’s.
“There’s a reason they cost a third of what another building would cost,” Fyles says.
Students and teachers say the learning experience in portables is compromised by poor lighting, erratic temperatures and noisy heating and air conditioning. The structures often are relegated to soggy fields or parking lots, near noise and vehicle exhaust.
As long as Lane is left to teach for years in a space built for temporary use, she sees no end in sight to distracted students or lost money.
“I’ve been pretty lucky in the portable that I’ve had,” Lane says. “But I know that there are cases around the district where they’ve had to go in and do some of those things, some deep cleaning of portables and other things because of mold or other unknown substances that are in there that are making people sick.”
Dave Blake totes a black bag stuffed with strange equipment through Geneva Elementary in Bellingham, Washington. A small entourage trails him down a hallway loud and crowded before recess.
A student asks who they are.
Blake’s reply, quick and rehearsed: “Ghostbusters.”
He’s looking for something you can’t see but, if you know about it, it will scare you.
Blake specializes in indoor air for the Northwest Clean Air Agency. He and his mentor Rich Prill, a retired indoor air specialist for Washington State University, have walked through thousands of classrooms and held seminars on the topic.
Experts like them have only recently begun to quantify indoor air pollution and its effects on student performance. Blake says they can dramatically improve air quality in just an afternoon, but the people who do their work in Washington can be counted on one hand.
“If you don’t look, you don’t know,” Blake says. “We’ve been into schools that were in very bad shape and by the end of the day, it’s a completely different story.”
On a rainy day, standing water surrounds Geneva Elementary’s portables. Their siding is weathered and ready to be replaced, Blake says.
Inside one, Blake pulls instruments from his bag to demonstrate one by one what he can detect in a classroom.
First he uses his nose.
“If you can smell the humanity and taste the humidity, you know you have a ventilation issue,” Blake says.
Next comes a device that resembles a remote control and detects carbon dioxide (CO2) levels.
He runs a wire through what looks like a windsock and holds one end to the CO2 monitor, the other to the ceiling vent. The tool, which Prill sewed for him from a lampshade, funnels air directly into the device for a better reading.
Blake uses carbon dioxide as an indicator of whether enough fresh air passes through a room or if students are breathing germs, allergens and chemicals that accumulate in stagnant air. All of these trigger asthma — one of the leading causes of both school absences and child hospitalizations.
When Blake started this work in 1995, Bellingham opened its doors to him first. It was a courageous move, he says. For most schools throughout Oregon and Washington — and the rest of the country — there is no Dave Blake. There is no ghostbuster to call.
“What’s the big whoop about indoor air? I had no clue,” Blake says. “You have to be trained to know that indoor air is important. And indoor air is always worse than outside air with very few exceptions.”
Indoor air quality problems are widespread in schools across the country, according to Brenda Doroski, director of the Center for Asthma and Schools at the U.S. Environmental Protection Agency. Issues include poor ventilation, mold, and radon in addition to improper use or storage of chemicals and pesticides, she says.
The first and only large-scale study of portable classrooms in particular was done by the California Air Resources Board in 2004, in response to numerous complaints.
The study found inadequate fresh air during 40 percent of classroom hours. It also found higher levels of formaldehyde — a chemical used in building materials linked to cancer and childhood asthma — that exceeded the state’s chronic exposure limits in nearly all portable classrooms. Levels in portables also more frequently exceeded acute exposure limits designed to protect against respiratory problems.
Such problems occur in all types of classrooms, particularly those where maintenance has lagged, but experts say they find them more often in portables.
“Formaldehyde levels were a little higher in the portables, some of the ventilation issues were greater, the lighting, moisture problems were a little greater,” says Peggy Jenkins, one of the study’s authors. “It did point to maybe the need for better maintenance and care for our classrooms.”
Since then, California and the federal government have adopted standards limiting formaldehyde emissions from wood products. The federal standards haven’t yet been fully implemented, and the majority of portables in use throughout the Northwest were constructed before such standards existed. Newer classrooms tend to have more gas emissions, experts say. Around 10 percent of portables in Oregon and Washington’s largest districts are newer than five years old.
No follow-up studies have been done since 2004 in or outside of California. The levels of such chemicals in Northwest classrooms remain a mystery.
Carbon dioxide levels have been studied. Separate analyses from Portland State University and Tacoma-Pierce County Health showed carbon dioxide levels in portable classrooms consistently exceeded what engineers consider acceptable carbon dioxide levels.
When those levels go up, student performance suffers.
Research has shown even moderately high carbon dioxide concentrations can significantly impair decision-making. Another study, which Blake co-authored, showed attendance in Washington and Idaho classrooms suffered with increased CO2. The problem worsened in portables, but the authors are unsure why.
“It could have been from volatile organic compounds, could have been the building materials, could have been mold and moisture issues,” Blake says.
If Shaylee Adams wasn’t such a good student, maybe she wouldn’t have gotten sick so often in fourth grade.
“I was probably sick for maybe like three months out of the school year,” she says. “Like three or four months.”
Shaylee qualified for Puyallup’s Quest program offering accelerated courses. The program put her in a portable all day.
Then came high fevers, coughing and swelling. But at the end of the year, she got better.
“We figured out that part of the reason was because the building at my school and the portable at Quest was making me sick,” she says.
She and two classmates in Lane’s World, Brandon Silowka and Hannah Peterson, have floated in and out of portables throughout their education. They recall classes so cold they wore jackets and saw their breath and classes so hot they shoved desks aside and laid on the floor. One portable lost power every couple weeks.
“Portables are definitely a problem,” Brandon says.
“Portables, they need to go,” Shaylee says.
For Hannah, a quiet girl who doesn’t say much until her classmates have left, it’s more personal than that.
“It feels as though we’re not their top priority anymore,” she adds. “Like the district doesn’t care enough about the students to take the temporary structure and make it something more permanent where we don’t have to worry about a dog barking outside and the teacher doesn’t have to stop and wait for the bus to go by. So … it feels as though we’ve been kind of pushed off to the side.”
Rudy Fyles and the rest of Puyallup’s school administrators say they care about their students. They just don’t see any alternative.
Requirements for all-day kindergarten and for smaller class sizes will force the district to add portable classrooms — even if the district’s student enrollment were to hold steady.
On top of these mandates there are also demographic reports showing the district will have to absorb 2,000 more students over the next five years.
When Kalles Junior High moved into a new building a few years ago, it was already over capacity. Billie Lane’s portable came with her.
Puyallup voters haven’t passed a bond for new construction in a decade. A bond for over $259 million failed two times in 2007. In 2010? Failed. 2013? Failed.
Thinking about that brings Lane, the only teacher on Puyallup’s bond advisory committee, to tears.
“Our priorities are messed up. Excuse me, this is going to bother me a little bit,” she says. “I don’t understand how we can spend money on sports arenas and on prisons and on so many things that have such a big ticket item to it, and we will not put that money towards our kids.”
Without her students in the room, she wonders aloud what message these classrooms send to them. Maybe they’ll see how they were treated and perpetuate it. Maybe they’ll take it as a challenge to their generation. She hopes it’s the second.
“I don’t know what to do,” she says. “ I’m not giving up.”
