The dress code for school-age children has been a subject of controversy for decades. Debates about student dress codes have also gotten courts involved, like the US Supreme Court ruling of 1969. Read on to learn about dress code statistics for schoolchildren.

Over 40% of elementary, middle, and high schools in America adopt some form of dress code for students. And at least 1 in 5 US public schools have standing dress code policies

Strict codes, sex-centric uniforms, and other elements have muddled the objectives of schools in several instances. And it’s important for parents, students, and education stakeholders to understand dress code trends better.

That’s why this guide looks at some of the most important school dress code statistics you must know. All the information in this post gives a better idea of dress codes and their perceived importance in schools.  

1. 42% to 56% of elementary, middle, and high schools enforce strict dress codes for students

National Center for Education Statistics (NCES)

In the 2017/2018 school year, more than 40% (42.6%) of students reported to the NCES that they enforced dress codes. Also, 61.6% of US middle schools reported that they enforced strict dress codes for students. 

56% of high schools also reported strict dress code policies for students were operational on their premises. 

However, these numbers do not reflect that US schools mandate uniforms for their students. Recorded data for schools that require their students to wear uniforms are low in the US. 

2. A US school district altered the dress code of 80 female students to curb ‘immodest’ appearances


Strict enforcement of dress codes in several US schools has been a subject of debate for years.

For example, Bartram Trail High School, Florida was in the news for dress code controversies in 2021. The school received flak from parents, students, and media houses for altering about eighty (80) pictures of female students. 

Alterations in the school’s yearbook for the 2021 school year appeared to target female students only. Comments from the school district said all alteration measures became necessary to ensure ‘modest’ dressing. 

All 80+ alterations were completed digitally without the consent of students. 

3. In the US, primary schools are twice as likely to require uniforms than high schools

US Department of Education

Continuing on with our dress code statistics for schoolchildren, 23% of primary schools in America require school-age kids to wear matching uniforms within their premises. It is not clear whether the number of kids enrolled in preschool was considered while compiling this data. 

Also, about 18% of US middle schools require their students to put on matching uniforms whenever it’s a school day. 

But the number of US high schools that require students to wear uniforms is much lower. 

Compiled data show that no more than 10% of US high schools require students to wear uniforms. That means 9 out of 10 high schools in the US have no rules making uniforms compulsory. 

4. Over 20% of all US public schools have dress code policies

National Center for Education Statistics

2 out of 10 public schools in America (elementary, middle, and high school) have stringent dress code policies for students. The policies range from mandating uniforms to banning signs and certain symbols, and so on.  

5. The first school uniform was introduced in the mid-16th century


Uniforms became compulsory across schools in the United Kingdom from 1552 onwards. Christ’s Hospital School, England is regarded as the first school to ever adopt the use of school uniforms for students. 

However, Christ’s Hospital School isn’t credited as the creator of school uniforms. The oldest record of standard uniforms is traceable to early 13th-century England.  

6. The US Supreme Court ruled in favor of freedom of expression through student dress codes in the late 1960s

American Civil Liberties Union

A landmark ruling by the US Supreme Court in 1969 (Tinker v. Des Moines) solidified the students’ right to free speech. In public schools, students can decide to protest with additions to their school wear. 

A then 13-year-old Beth Tinker and other students were suspended for protesting the Vietnam War with black armbands. In a 7–2 ruling, the court said that students are free to express themselves, even inside their school premises.

7. UK parents pay more than £300 per year for mandatory school uniforms


Numbers show that at least £300 is spent on school uniforms for kids in the UK every year. The average is much higher in expensive schools and might exceed £400 in some institutions. 

8. A UK study says that more than 20% of parents grapple with the cost of maintaining dress codes

The Guardian

At least 2 in 10 parents in the UK are struggling with the maintenance costs of their children’s school uniforms. Low-income earners bore the brunt more than middle-class parents. 

9. Over 70% of parents and school officials believe that uniforms suppress peer pressure


Several studies have shown that uniforms in schools can be responsible for reduced peer pressure among students. Some numbers range this reduction at 70% or higher in some school districts. 

10. Grey and blue are the most common school dress code colors in the USA and the UK

National Association of Elementary School Principals (NAESP)

The NAESP conducted a study and discovered that grey, white, and red uniforms are common in the UK. Also, the study revealed that blue and white are common colors found in uniforms across several US schools.
