The short answer
A first resume is not a list of paid jobs. It is a short, honest page that tells a manager three things: what you have done, when you can work, and how to reach you. If you have never had a job, your experience comes from everything else you have done where someone counted on you.
Start with the list below. Pick everything that fits, give each one a plain name, and write two or three short lines about what you did.
What counts as experience
A food bank, a place of worship, a community event, a library, an animal shelter. Hours you did for school count too.
Someone trusted you with their kids or their pets. Say how often, and for how long you have done it.
Showing up to practice, a role on the team, helping coach younger players, a season you finished.
Student council, a school band, a yearbook, a robotics or debate club, a fundraiser you helped run.
A group project, a science fair entry, a presentation, something you built. Say what your part was.
Helping at a family shop, cutting lawns, shovelling snow, tutoring, selling things you made.
Certificates count too: first aid and CPR, a lifeguard or swim instructor course, a food handler certificate, a babysitting course. Put them in their own short section.
How to write each line
Every line answers one of three questions: what did you do, how much or how often, and what came of it. Start with a plain action word, leave out "I", and keep it to one line.
Use the present tense for things you still do and the past tense for things you finished. Keep each entry to two or three lines. If you cannot think of a number, write what you did in plain words and leave it there. A plain, true line is better than a big one you cannot explain.
Do not dress it up
It is tempting to paste your life into a chatbot and ask it to make you sound impressive. What comes back usually sounds like everyone else's resume: "results-driven", "dynamic", "passionate self-starter". Managers who hire for first jobs read a lot of these, and they skip them.
The bigger problem is the interview. Anything on your resume is fair game, so every line should be something you can talk about for a minute in your own words. If a line says you "managed" something, be ready to say who you managed and what happened.
Tell them when you can work
For a part-time job, when you can work matters as much as what you have done. Put a short availability line near the top, right under your name or summary. For example: "After school and weekends, about 12 hours a week." It saves the manager a question, and it shows you have thought about the job as a real commitment.
The order that works for a first resume
Put the strongest things near the top, where a busy reader looks first.
- Your name, city, phone number and a simple email address (your name, not a nickname)
- A short summary, if you have something real to say (optional)
- When you can work
- Experience: paid work, odd jobs, babysitting, family business
- Volunteering, teams and clubs
- School, and when you expect to finish
- Certificates
- Skills you can show, and languages you speak
Leave out your age, your full street address, and a photo. A manager doesn't need any of them to decide, and in Canada a photo on a resume is not the norm.
Volunteer hours count
If you are in high school, you may already have hours you can use. Many schools and some whole provinces and states ask students to do community service before they graduate. In Ontario, every student needs at least 40 hours of community involvement to earn their high school diploma. In Maryland, every public school student needs at least 75 hours of service-learning. Other places have their own rules, or leave it to the school, so ask your school what counts.
Whatever you did to earn those hours is experience, and it can go on your resume like any other volunteering: a plain title, where, roughly how long, and a line or two about what you did.
One page, then practise saying it
A first resume fits on one page. When it is done, read each line out loud and imagine a manager asking, "Tell me more about that." If you can answer, the line stays. If you would have to make something up, change the line until you would not.
