Do uniforms make schools better?

Schools, parents, and students frequently clash over the issue of regulating what students may and may not wear to school. These controversies often pegged to the culture war of the moment touch on everything from gender and sexuality to politics, race, and religion. In 2021, a group of about 50 students in Georgia protested their middle school’s dress code for being discriminatory against BIPOC girls by wearing t-shirts every Friday emblazoned with the words “sexist,” “racist,” and “classist.” In 2022, a fight between students, staff, and police officers broke out at a Pennsylvania high school when hats and hoodies were banned as part of a revision by the school board to the school’s dress code. And in 2023, two Michigan middle schoolers, via their mother, sued their school district after they were banned from wearing “Let’s Go Brandon” sweatshirts.

Are school uniforms the best solution to this contentious debate? If every student is wearing the same outfit, will a host of campus problems be solved? Researchers are divided over how much of an impact — if any — dress policies have on student learning. There are multiple studies with conflicting conclusions, plus books such as 2018’s The Debate About School Uniforms , but the argument wears on, with a list of pros and cons on each side.

Why do some public schools have uniforms?

In the 1980s, public schools were often compared unfavorably to Catholic schools. Noting the perceived benefit that uniforms conferred upon Catholic schools, some public schools decided to adopt a school uniform policy.

President Clinton provided momentum to the school uniform movement when he said in his 1996 State of the Union speech, “If it means teenagers will stop killing each other over designer jackets, then our public schools should be able to require their students to wear school uniforms.”

The pros and cons of school uniforms

According to proponents, school uniforms:.

• Help prevent gangs from forming on campus

• Encourage discipline

• Help students resist peer pressure to buy trendy clothes

• Help identify intruders in the school

• Diminish economic and social barriers between students

• Increase a sense of belonging and school pride

• Improve attendance

Opponents contend that school uniforms:

• Violate a student’s right to freedom of expression

• Are simply a Band-Aid on the issue of school violence

• Make students a target for bullies from other schools

• Are a financial burden for poor families

• Are an unfair additional expense for parents who pay taxes for a free public education

• Are difficult to enforce in public schools

Uniforms vs. dress codes

Schools and districts vary widely in how closely they adhere to the concept of uniformity.

What’s a dress code?

Generally, dress codes are more relaxed than uniform policies. Sometimes, however, dress codes are quite strict with requirements that are potentially viewed as biased based on race or gender. In 2020, two Black male students in Texas, cousins with West Indian heritage, were suspended for wearing dreadlocks in supposed violation of the district’s hair and grooming policy, part of the dress code. The elder one, a senior, was told he couldn’t attend prom or graduation until his dreads were trimmed. In 2022, girls on the track team at an Albany, NY high school were sent home for wearing sports bras at practice.

Uniforms are certainly easier for administrators to enforce than dress codes, largely because the ACLU (American Civil Liberties Union) can be depended upon to protect a student’s “right to express themselves.” The ACLU believes dress codes are often used to, “shame girls, force students to conform to gender stereotypes… punish students who wear political and countercultural messages. Such policies can be used as cover for racial discrimination… Dress codes can also infringe on a student’s religious rights…” To successfully enforce a dress code, insists the ACLU, the school must prove the student’s attire, “is disruptive to school activities.”

The ACLU’s dress code stance is regularly supported by federal courts , like the 2023 lower court ruling in North Carolina that ended a charter school decree that girls couldn’t wear pants to school. ACLU lawyers claimed this violated Title IX because the dress code “discriminated against female students by limiting their ability to fully participate in school activities, such as using the playground.” The U.S. Supreme Court later declined to take up a case challenging the lower court’s ruling.

Check with your school to see what the dress code is, as they can be fairly specific. In Tulsa, Oklahoma, for example, the dress code prohibits :

• Symbols, mottoes, words or acronyms that convey crude, vulgar, profane, violent, death-oriented, gang-related, sexually explicit, or sexually suggestive messages.
• Symbols, mottoes, words or acronyms advertising tobacco, alcohol, or illegal drugs or drug paraphernalia.
• Symbols, mottoes, words or acronyms identifying a student as a member of a secret or overtly antisocial group or gang or that identifies a student as a member of an organization that professes violence or hatred toward one’s fellow man.
• Visible and permanent tattoos/brands incompatible with the standards set forth herein shall be covered to prohibit their display.
• Excessively large or baggy clothes

What’s a uniform?

School uniforms worldwide can widely range from nondescript to bizarre. (Extreme examples from China, Australia, and the UK on this YouTube video ) Most public school outfits in the USA are quite casual, with a “ common type ” for boys often a polo shirt in a solid color, with pants in khaki, black, or navy blue. A girl’s uniform is often a skirt and a white buttoned-up shirt. Dress shoes are frequently required for both genders.

In the United States, low-income families spend an average of $249 on a child’s school uniform annually, far less than the typical Australian student’s $578. But still, the cost is sometimes viewed as unfair because public education is intended to be free, paid by tax dollars, not “a stress for families on lower incomes.” The ACLU believes that public schools should provide free school uniforms , because the expense is unconstitutional, and it increases wealth inequity.

What research says about school uniforms

In 2006, Virginia Draa, professor at Youngstown State University, reviewed the impact of school uniforms at 64 public high schools that had larger percentages of economically disadvantaged and minority students than other urban schools. Her conclusion surprised her: “I really went into this thinking uniforms don’t make a difference, but I came away seeing that they do… I was absolutely floored.” Her analysis determined that the schools with uniforms improved their students attendance, and graduation rates rose an average almost 11 percent.

In 2022, Ohio State University and University of Pennsylvania researchers reached a contrary opinion in their report titled “ School Uniforms and Students Behavior: Is There a Link? ” Their view was that, in general, evidence that school uniforms improve social skills in the students was “inconclusive.” The solitary praise they provided to uniform-wearing was noting there was “some indication that low-income students in schools that required uniforms demonstrated better school attendance than low-income students in schools that did not.”

What to believe? Jury is still out.

What do students think about uniforms?

A student discussion: pros and cons of uniforms

Editor’s note: This video is part of our high school milestones series about communication skills. The students in this video discuss the pros and cons of school uniforms.

A University of Nevada, Reno, survey of 1,848 middle school students, published in 2022, revealed that 90 percent did not like wearing a uniform to school . Only 30 percent believed the uniforms “might reduce discipline issues, a mere 17 percent thought the uniform helped them focus at school, 34 percent believed their school was safer due to the uniforms and 37 percent said, “I worry less about my appearance” due to the uniform requirement.”

An earlier study, also in Nevada, displayed similar unpopularity with newly instituted uniforms among middle school students. However, when the researchers looked into school discipline and local police records and compared them to the prior year’s data, discipline referrals were down 10 percent, there were 63 percent fewer police log reports, and incidences of graffiti, fights, and gang-related activity were all down.

It’s a big issue

A new trend is the mounting pressure to establish dress codes for teachers. Apparently, the same casual mindset toward revealing outfits is cropping up in the ranks of our teachers.

The debate over uniforms in public schools encompasses many larger issues than simply what children should wear to school. It touches on issues of school improvement, freedom of expression, and hot-button culture wars. It’s no wonder the debate rages on.

The Pros and Cons of School Uniforms for Students

Student Safety

Focus on education, attendance rates, discipline issues, dress code enforcement, cost for families, impact on self-esteem.

The debate over whether students should wear school uniforms has been going on for more than a decade. Some people argue that uniforms have a positive impact on the school environment by promoting inclusivity, confidence, and a sense of belonging. Others fear that school uniforms prevent kids from expressing themselves through their clothing choices.

The research on school uniforms is often mixed. While some schools have found uniforms to be beneficial, other research has found that they have little effect. Some studies have even reached the conclusion that requiring school uniforms can be harmful for students.

Let's take a closer look at some of the potential benefits, as well as the challenges, of requiring students to wear uniforms.

Some people think that school uniforms can help make schools safer for kids. When Long Beach, CA, required all students in grades K–8 to wear uniforms, reports of assault and battery decreased by 34%.

Additionally, assault with a deadly weapon decreased by 50%, fighting incidents declined 51%, and sex offenses dropped by 74%. Possession of weapons dropped by 52%, possession of drugs went down 69%, and vandalism was lowered by 18%.  

The Sparks Middle School in Nevada reported a decrease in gang activity after instituting a uniform policy. They also reported a drop in fights, graffiti, property damage, and battery. Overall, there was a 63% drop in police reports.

Other proponents of school uniforms report that it prevents students from concealing weapons under clothing. And some also believe intruders would be recognized faster, making the students and staff safer in the event someone from the community tries to enter the school.

Not all studies have found that uniforms reduce discipline issues, however. In fact, a peer-reviewed study found that school uniforms increased the average number of assaults by about 14 per year in the most violent schools.  The Miami-Dade County Public Schools Office of Education Evaluation and Management found that fights in middle schools nearly doubled within one year of making uniforms mandatory.  

For many students, clothing can be a major source of stress. Not having certain brand name clothing or not wearing fashionable items could lead to feelings of insecurity. 

Some people feel students are better able to concentrate on school when they all wear the same clothing. Researchers in Australia noted that students who wear uniforms had improved discipline and academic performance.  

Not all studies have found that uniforms improve grades, however. In fact, at least one study found that school uniforms had a negative effect on achievement.  

Kids may show up to school more often when they’re wearing uniforms. A study by researchers at the University of Houston found that the average attendance rate for girls in middle and high school increased by 0.3 to 0.4 percent after school uniforms became mandatory.   A study by Youngstown State University also found that attendance rates increased and suspensions decreased once students began wearing uniforms.   

Students may also be more likely to show up to school on time when they have to wear uniforms. If they don’t have to spend time choosing what to wear every morning, students are able to get out the door more quickly. This means fewer late arrivals.

Proponents of uniforms report that it can improve behavior in students. One school that found this to be true is the John Adams Middle School in Albuquerque, NM. When they mandated school uniforms, discipline referrals dropped from 1,565 in the first semester of the previous year to 405.    

An Australian study also concluded that students wearing uniforms were more disciplined and they listened significantly better. Classes were also more likely to start on time.  

Not all studies have found this, however. Some research has found that disciplinary issues and bullying didn’t decrease after instituting a mandatory uniform policy.

Many school officials spend a lot of time policing dress codes . Enforcing policies can require a lot of resources as teachers may send kids to the office, and administrators have to determine whether clothing is too baggy, inappropriate, or revealing.

Kids who violate dress codes may spend a lot of time in the office awaiting consequences, or they may receive suspensions for repeated violations. School uniforms can keep kids in the classroom more and prevent staff from wasting time trying to enforce policies.

Parents may spend less money on school clothes when kids wear uniforms. There is less pressure to buy expensive name-brand clothing, and school uniforms might be more affordable.

Opponents of school uniforms, however, say that requiring parents to buy specific articles of clothing goes against the idea that students should be given free education. When public schools force parents to buy uniforms, this could be placing a hardship on some families.

Proponents of uniforms report that they have a positive impact on student self-esteem .   Wearing the same clothing as everyone else means that students don’t have to worry about whether their clothing choices will be acceptable to their peers.

But opponents argue that uniforms may have a negative impact on some students’ body image. Research conducted at Arizona State University found that students without uniform policies actually reported higher self-perception scores than students with uniform policies.  

When all students wear the same clothing, they may be more likely to compare themselves to their peers as clothing fits differently on everyone’s body.

The Problem With Uniform Research

Although there are many studies that examine the potential benefits and drawbacks of uniforms, many of them revealed correlation, rather than causation. Just because grades went up or behavioral problems went down, there’s no way of knowing that the reason for the change was due to uniform policy. There are many other factors that may have influenced these issues.

A Word From Verywell

Before any school adopts a uniform policy, it may be wise to review the literature. While there certainly may be a lot of benefits to making uniforms mandatory, there are also some potential drawbacks and challenges you might face. Parents, teachers, and administrators may want to weigh the pros and cons before instituting any type of clothing policy for students.
