Students write all the time. They send texts to friends, post on social media, write essays, email teachers, and complete classroom assignments. The challenge is helping them change their writing style for different audiences, purposes, and situations. This is why it’s important to understand the difference between formal and informal writing.
Formal writing uses professional, precise, and organized language for school or work. Informal writing sounds more like a conversation and feels personal. Choosing the right style depends on who you’re writing for, why you’re writing, and the situation.
What Is Formal Writing?
Formal writing is organized, uses precise words, and has a tone that matches academic or professional settings. Students see this style in essays, research papers, presentations, and other school assignments.
Formal writing doesn’t have to be complicated. Good formal writing is clear and has a purpose. Students should use specific words, organize their ideas logically, make sure their thoughts are complete, and include evidence when needed.
Expectations for formal writing can change with each assignment. Rather than giving students a long list of things not to do, invite students to think about who they’re writing for, why they’re writing, and what kind of writing it is.
What Is Informal Writing?
Informal writing sounds like everyday conversation. Students use it in texts, on social media, in personal emails, journal entries, and sometimes in classroom writing.
It can include contractions, everyday words, humor, opinions, and slang. But informal writing shouldn’t be messy. Students still need to be clear and organize their ideas.
The key is understanding which writing choices fit the audience and situation.
Formal vs. Informal Writing: The Key Differences
| Formal Writing | Informal Writing |
| Academic or professional tone | Conversational tone |
| Precise vocabulary | Everyday vocabulary |
| Clear, structured organization | May have a looser structure |
| Slang is generally avoided | Slang may be appropriate |
| Often more objective | Can be personal |
| Common in essays and reports | Common in texts and personal writing |
These categories aren’t rigid. An email to a principal can be professional without sounding like a research paper. A blog can be conversational and still be carefully written.
Students need to understand levels of formality, not just two boxes labeled formal and informal.
Helping Students Write for Different Audiences
Knowing how to shift between formal and informal writing builds audience awareness. Students learn to make intentional choices about tone, vocabulary, organization, evidence, and detail.
This skill isn’t just for English class. Students use it when writing a science lab report, building a historical argument, emailing a counselor, or preparing a resume. Audience awareness is important across all subjects.
Formal vs. Informal Writing Examples for Students
Seeing examples side by side makes the differences clearer.
Informal:
A lot of students get stressed because they have way too much homework.
More formal:
Many students experience stress when they are assigned excessive amounts of homework.
Informal:
I think schools should start later because teenagers are always tired.
More formal:
Schools should consider later start times because adolescents often experience insufficient sleep.
Too informal for an email to a teacher:
Hey, I wasn't here yesterday. What'd I miss? (This one walks into the room in pajama pants.)
More appropriate:
Hello Ms. Garcia, I was absent yesterday and would like to make up the work I missed. Could you please let me know what I need to complete? Thank you.
Does Formal Writing Mean Using Bigger Words?
Students sometimes try to make academic writing sound “smart” by using unnecessarily complicated language.
Overwritten:
The utilization of technological devices can facilitate the enhancement of educational outcomes.
(That’s a lot of words to say something simple. It sounds like the sentence put on a suit two sizes too big and is still trying to walk.)
Clear and formal:
Technology can improve student learning.
Formal writing should be clear and precise, not complicated. Encourage students to pick the simplest words that say what they mean.
What About Contractions and First Person?
Students may hear rules such as “never use contractions” or “never use I.” In reality, those choices depend on the assignment.
A formal research paper may call for a more objective style, while a reflection or college essay may require first person. Contractions may feel too casual in some academic assignments but perfectly natural in professional or conversational writing.
A better question to ask is: Does this choice fit the audience, purpose, and assignment?
A Better Way to Teach Formal vs. Informal Writing
Students often learn formal writing through rules about what not to do. These guidelines can help, but they can also make students write too stiffly.
Instead, help students think about who they’re writing for, what they want to achieve, and what tone fits the situation.
This approach helps students move from just following rules to making thoughtful choices in their writing.
How to Teach Formal vs. Informal Writing by Grade Level
Students can learn about formal and informal writing at any grade. What changes as they grow is how complex their writing decisions become.
Elementary School: Start With Audience
Make it concrete. Have students write the same message to two people, like a friend and the principal. Compare the versions together. Did the greeting change? Did the words change? Which one sounds more serious? At this stage, focus on the simple idea that we change our writing based on who will read it and why.
Middle School: Practice Revising for Tone
Middle school students can start spotting what makes writing sound formal or informal. Give them a casual paragraph and ask them to rewrite it for an academic audience. Have them look for slang, vague words, conversational phrases, unsupported claims, and places where clearer language would help. Most importantly, ask them to explain why they made each change.
High School: Build Flexibility
You can help students go beyond seeing writing as just formal or informal. Give them the same message and ask them to adapt it for an essay, an email to a teacher, a scholarship application, a presentation, or a social media post. Then talk about how their choices changed. The goal is for students to decide on their own what level of formality fits the audience, purpose, type of writing, and situation.
| Grade Band | Main Skill |
| Elementary | Recognize that writing changes for different audiences |
| Middle School | Revise writing to change tone and formality |
| High School | Independently choose the appropriate level of formality |
Formal and Informal Writing Across Content Areas
Formal and informal writing isn’t just an ELA skill. Students adjust how they communicate throughout the school day, often without realizing it. A lab report calls for a different tone than a quick notebook observation, just as a historical argument requires different writing choices than a personal reflection.
| Content Area | More Formal | Less Formal |
| ELA | Literary analysis, argument | Journal or discussion response |
| Science | Lab report, research summary | Notebook observation |
| Social Studies | Historical argument | Reflection or simulation |
| CTE | Resume, professional email | Peer communication |
Pointing out these differences across content areas helps students see the bigger picture. The right level of formality depends on the audience, purpose, and task, not simply the subject. When teachers use that same language across classrooms, students can begin transferring what they know about writing from one class to another instead of treating every assignment as a completely new set of rules.
Helping Students Move from Informal to Formal Writing
Telling students to “make it more formal” isn’t very helpful. Instead, show them what a better revision looks like. For example, 'A lot of things caused the problem' could become 'Several economic and political factors contributed to the conflict.' Instead of saying a character 'totally freaks out,' a student could write that the character 'reacts with intense fear.'
Teach students to spot vague words, slang, casual phrases, weak verbs, and broad claims. The goal isn’t to make their writing complicated, but to help them pick clearer, more precise words that fit the audience and purpose.
Give Feedback Students Can Use
Writing “too informal” on a student’s paper is a bit like saying “do better” without handing them a map. It tells them something is wrong, but not how to fix it. Give feedback that helps students make a specific change in their writing.
| Instead of saying... | Try asking... |
| “Too informal.” | “How could you adjust the tone for an academic audience?” |
| “Word choice.” | “Is there a more precise word you could use here?” |
| “Don’t use slang.” | “What wording would better fit your audience?” |
| “Don’t use ‘I’ or ‘you.’” | “Does this point of view fit the purpose of this assignment?” |
| “Make this more formal.” | “What could you change to make this sound more appropriate for the reader?” |
The goal is to help students do more than just fix one sentence. When feedback connects to audience, purpose, and tone, students learn the kinds of questions they can ask themselves as they write.
Try It in the Classroom: From Informal to Formal
This quick activity, adapted from an Empower Educational Connections writing lesson, gives students immediate practice shifting from conversational to more formal writing.
Best for: Grades 6–8
Time: 15–30 minutes
Display this argument:
I think schools should totally give us longer lunch periods. Twenty minutes just isn't enough. By the time you get your food, lunch is basically over. Longer lunches would make school way better.
Ask students what makes it sound conversational. Then model revising one sentence:
Informal: Twenty minutes just isn't enough.
More formal: A twenty-minute lunch period may not provide students with enough time to get and eat their meals.
In pairs, have students revise the rest of the paragraph. Tell them to focus on tone, word choice, support, and point of view. After a few minutes, ask pairs to share one revision and explain why the change better fits an academic audience.
Close the activity by having each student find one sentence in their own recent writing that could be more formal, revise it, and briefly note why the new version works better for the reader.
This short cycle—notice, model, revise, reflect—helps students practice the exact decision-making they’ll need on future assignments.
How School Administrators Can Support Consistent Writing Expectations
Students can get mixed messages about formal writing. One teacher may prohibit contractions or first person while another allows them. Some differences make sense because writing conventions vary by subject and assignment.
School leaders can help by creating shared language around audience, purpose, genre, and tone. Students don’t need identical rules in every classroom. They need a consistent way to think about the choices writers make.
Should Teachers Correct Informal Writing?
It depends on the assignment. Informal language may need revision in a research paper but could be completely appropriate in a journal entry or reflection.
Before correcting a student’s tone, ask if formal writing was really expected. If it was, give specific feedback instead of just writing 'too informal.' Show students what needs to change and explain why.
Formal Writing Is Not Always the Goal
Students need to know how to write formally, but they also need to be flexible. An email shouldn’t sound like a five-paragraph essay, and a scholarship application shouldn’t sound like a text to a friend.
When students aren’t sure about tone, give them a simple test:
Would I say this the same way to my best friend, my teacher, and a future employer?
If not, what should change?
The goal is to help them make their writing fit the reader.
Final Thoughts
Students don’t need to write formally all the time—they need to know how to choose the right tone for the audience, purpose, and situation. The next time you look at a piece of student writing, try asking one simple question: “Does this fit the reader?” When you help students make that decision intentionally, they begin thinking like writers instead of rule-followers, and you get clearer, more purposeful work. You’ll walk away knowing you just helped them build a skill they’ll use in every class and far beyond school.
Frequently Asked Questions
Formal writing uses more professional, precise, and structured language, while informal writing is more relaxed and conversational. The best style depends on the audience, purpose, and situation. Students should learn that neither style is automatically better. Strong writers know how to adjust their language to fit the task.
Formal writing prepares students for the communication they’ll encounter in school, college, careers, and everyday life. Students use these skills when writing essays and reports, emailing teachers or employers, completing applications, and communicating in professional settings. Learning formal writing also helps students think more carefully about audience, tone, word choice, and organization.
No. Informal writing has an important place in communication. A journal entry, text message, personal reflection, or discussion response may call for a relaxed and conversational tone. Informal writing can still be clear, organized, and effective. The goal is to help students recognize when an informal style fits and when they need to shift to something more formal.
Sometimes. Contractions and first person aren’t automatically wrong in formal writing. Their use depends on the assignment, genre, audience, and expected tone. A personal reflection or college essay may require first person, while a formal academic argument may call for a more objective approach. Instead of teaching these as absolute rules, help students understand why certain choices work better in certain situations.
Start with audience and purpose rather than a list of words or constructions students can’t use. Show students examples of formal and informal writing and have them compare the differences. Then teach specific revision moves, such as replacing vague or conversational language, choosing stronger verbs, supporting broad claims, and adjusting tone. Most importantly, ask students to explain why a revision is a better fit for the audience and task.
