How many classrooms in America’s largest school districts are missing a teacher when the school year starts?
A small but significant number, according to new data obtained from those districts, though it varies widely. In Los Angeles and Houston, virtually all teaching jobs were filled. But in Chicago, nearly 6 percent of teaching jobs were vacant.
Districts used their own definitions for a “vacant” position, meaning the numbers may not be directly comparable. Still, they highlight how several big districts, by their own admission, are not able to fill teaching jobs by the time school starts. Research and experience suggests that students stand to suffer, particularly those in already struggling schools.
Districts with vacant teaching positions have less-than-ideal options. They can use short- or long-term substitutes; raise class sizes; or leave non-classroom positions like reading specialists unfilled.
Researchers and advocates say the problem can be addressed through a combination of short-term policies — like improving hiring policies that make it difficult to get into the classroom quickly — and long-term reforms, such as improving pay and working conditions to make teaching a more attractive job.
Matt Kraft, a Brown University professor who has studied how students are affected when their teacher who is hired late, summed it up: “It’s bad for kids,” he said.
In Chicago, budget questions lead to empty jobs
Chalkbeat requested the number of vacant or unfilled teaching positions at the beginning of the school year from the 15 largest school districts in the country, as well as how many teachers were employed. Their answers varied widely.
In Chicago, which was recently lauded as the urban district where students make the fastest improvements, there were nearly 1,300 teacher vacancies. As the district serves almost 400,000 students, this suggests that tens of thousands of students were affected.
A spokesperson for Chicago Public Schools said funding issues that left principals unsure of how much money they would have to hire teachers were at the root of the high vacancy rate.
“Last summer’s budgeting process was marked by an unprecedented level of uncertainty due to the state’s delay in funding education,” Emily Bolton said in a statement. School budgets would be released early this year, she said, giving principals more time to plan.
She said that if citywide social work and nursing positions — which are officially classified as teaching positions — were excluded, the vacancy rate would fall to 4.5 percent. Bolton also provided data showing that the number of open positions had been cut in half by the beginning of December.
Hawaii, which has one statewide district, reported 470 teaching vacancies to start the year.
“Filling teacher vacancies is one of the greatest challenges, as Hawaii shares the national trends of increasing teacher shortages and fewer numbers of individuals entering the profession,” said Donalyn Dela Cruz, a spokesperson for the Hawaii Department of Education.

Vacancy rates may not be comparable.
Mireille Ellsworth, a high school teacher in Hawaii for over a decade, says she sees positions sit empty every year. It has a significant impact, especially when the vacant teachers would otherwise be assisting her students with disabilities.
“When I start the school year with a teacher that is not a [special education] teacher — just a substitute — that is really difficult,” she said. “They’re supposed to be helping with … adapting the lessons and the curriculum to the students’ unique needs.”
Including Chicago and Hawaii, nine of the 15 surveyed districts reported a vacancy rate of over 1 percent.
Should the numbers be a major concern for policymakers? On one hand, all 15 of districts reported that the vast majority of their teaching positions were filled. But in large districts, having even a small share of positions vacant means a substantial number of students going without a dedicated teacher.
“This is one where percentages are less important than the absolute number,” Dan Weisberg, the head of TNTP, a consulting group that has worked with districts to overhaul their hiring practices. “Getting close is not good enough — you need to fill every one of those vacancies.”
Some districts report doing so. Los Angeles, a district about the size of Chicago, said there were only 12 open positions at the start of the year. A district spokesperson credited recruitment practices, partnerships with local teacher preparation programs, and a program to award early contracts to certain candidates in hard-to-staff schools. The district has also touted its retention rate among novice teachers: 94 percent in the 2015–16 school year.
Kraft, the Brown professor, warned that the true number of vacancies may be higher than districts report, as some may manipulate definitions of “vacant” or have principals who attempt to hide vacancies to avoid having a teacher placed in their school.
“I think you can take [these numbers] as a lower bound,” Kraft said.
How it plays out inside classrooms
Classrooms without full-time assigned teachers aren’t just a logistical problem for schools. Those vacancies also mean students learn less.
That’s according to peer-reviewed research from Kraft, along with Brown’s John Papay. They found that students taught by late-hire teachers had slightly lower math and reading scores on year-end exams.
The study suggests that the harmful effects come not just because students get off to a slow start when a teacher is hired late, but because late-hired teachers are less effective than others. This highlights a potential hidden cost to schools that hire late: top teachers have already been snapped up.
Poor students, students of color, and students who attend struggling schools are more likely to bear those costs.
An analysis by the Chicago Teachers Union found that vacancies in the city were concentrated on schools on the south and west side, which serve more students of color and those in poverty. And Kraft’s research on an anonymous urban district in the South found that schools with more vacancies tended to serve more low-income students. “In some ways, your averages mask the real story,” he said.
Meanwhile, Kraft points to some ways to avoid late hiring: creating a streamlined hiring process, ensuring principals realize the detrimental effects of late hiring, and setting school budgets as early as possible.
Those budget timelines can be critical, because some districts have had to issue layoff notices only to scramble to rehire teachers later. Research shows that this causes teachers to leave their schools, even if their positions are not ultimately eliminated.
Sarah Rothschild, an analyst for the Chicago Teacher Union, said this has been a problem. Pointing to budget issues, Chicago Public Schools regularly lays off teachers in the summer and then rehires for the same position months later, “at which point those people left for the suburbs or other jobs,” Rothschild said.
Offering bonuses for hard-to-staff positions, like those in special education and in high-poverty schools, could also help. Recent research has found that this approach is an effective way to retain teachers, and fewer teachers leaving means the district needs to make fewer hires.
More fundamentally, improving teacher salaries and working conditions is likely to attract new teachers and get others to stay. “That’s a big, long-term solution — not a quick fix,” said Kraft.
Corey Rosenlee, the head of the Hawaii State Teachers Association, emphasized pay, arguing that the state needs to spend more on schools.
“It’s not going to encourage people to go into the profession if they feel they can’t make a living off of it,” he said.
