How far back should a resume go?
Your resume should go back 10 to 15 years for most jobs. That is long enough to show your growth and current skill level, and short enough to keep your resume to one or two pages.
Older experience is not worthless. It is just less useful to a hiring manager deciding whether you can do the job today. Software, equipment, regulations and job titles change, and duties from 20 years ago often describe a more junior version of you.
The 10 to 15 year rule is a default. Relevance always wins. If an older job proves you can do the work, it belongs on your resume.
How far back should a resume go in your situation?
| Your situation | How far back to go | What to do with older work |
|---|---|---|
| High school or college student | Everything relevant | Include part-time jobs, volunteering and activities |
| Early career (under 10 years) | Your full professional history | Drop high school jobs once you have 2 or 3 professional roles |
| Mid-career (10 to 20 years) | 10 to 15 years | Leave off or list in an Earlier Career section |
| Senior professional (20+ years) | About 15 years | Summarize earlier roles in one or two lines |
| Career changer | Any relevant role, regardless of date | Lead with a Relevant Experience section |
| Returning after a long gap | Your last relevant roles, even if older | Add recent training, volunteering or freelance work |
| Federal job on USAJOBS | Relevant experience that proves you qualify | Stay within the two-page limit |
If you are not sure whether something older fits, check it against the job posting. Does it show a skill, license or result the posting asks for? If yes, find a way to include it.
When should you include older jobs on a resume?
Include a role from more than 15 years ago when one of these is true:
- It is directly relevant. You managed a pharmacy 18 years ago and are applying to manage one again.
- It shows a skill the job requires that your recent jobs do not. For example, earlier bookkeeping work when you are applying for an office manager role.
- It is part of a promotion path. If you started as a cashier and rose to store manager at the same company, show the whole climb. See how to list a promotion on a resume for formats.
- It is a well-known employer or project in your field. A recognizable name can open a conversation.
- It explains a license or credential. Some licenses require documented hours or years in the field.
Leave older roles off when they repeat what your recent jobs already show, or when they involve tools and duties that no longer exist.
How do you list older experience? Use an Earlier Career section
An Earlier Career section lets you mention older roles without spending a full entry on each. List the title, employer and location, and leave off the dates.
Here is an example for a fictional operations manager with 22 years of experience:
Earlier Career
Shift Supervisor, Northwind Logistics, Columbus, OH
Inventory Control Clerk, Fabrikam Manufacturing, Dayton, OH
Customer Service Representative, Woodgrove Bank, Dayton, OH
If space is tight, use a single sentence instead:
Earlier Career: Held supervisor, inventory control and customer service roles at Northwind Logistics, Fabrikam Manufacturing and Woodgrove Bank.
You can also add one short highlight when an older role has a result worth keeping:
Earlier Career: Inventory Control Clerk, Fabrikam Manufacturing. Rebuilt the parts numbering system used across two plants.
Before and after: trimming a 25-year work history
Here is how a fictional facilities manager, Dana Ruiz, cut her resume from three pages to two.
| Before | After |
|---|---|
| 7 jobs listed in full, back to 2001 | 4 jobs listed in full, back to 2011 |
| 6 to 8 bullets for every job | 5 bullets for the current job, 3 for older ones |
| Separate entries for 3 jobs from 2001 to 2010 | One Earlier Career line naming those roles |
| Graduation year from 2000 | Degree and school only |
| Skills included discontinued software | Skills list matches the current job posting |
Nothing she cut was relevant to the facilities manager roles she was applying for. Everything a hiring manager needed stayed on page one.
How many jobs should you list on a resume?
Most resumes list 3 to 5 jobs in the main experience section. The real limit is your time window and page count, not a fixed number.
| Career stage | Typical number of jobs | Bullets per job |
|---|---|---|
| Student or entry level | 1 to 4, including part-time and internships | 2 to 4 |
| Mid-career | 3 to 5 | 3 to 5 for recent roles, 2 to 3 for older |
| Senior | 4 to 6, plus an Earlier Career line | 4 to 6 for the current role |
If you have many short jobs, such as seasonal, temp or gig work, group them under one heading:
Delivery Driver (Contract), multiple app-based delivery platforms, Tulsa, OK, 2022 - 2024
For people with a long work history, keeping the job count down is also the easiest way to control length. Our guide on how long a resume should be shows what fits on one page versus two.
Should I include high school on my resume?
Include high school on your resume if it is your highest level of education or you are still a student. Remove it once you have a college degree, associate degree or postsecondary certificate.
| Your education | Include high school? |
|---|---|
| Currently in high school | Yes, with expected graduation date, GPA if 3.0 or higher, and activities |
| High school diploma or GED, no college | Yes, list the school or GED and year if recent |
| Some college, no degree | Optional. List the college coursework first |
| Associate degree, bachelor’s degree or higher | No |
| Trade school certificate or apprenticeship | Usually no. List the certificate instead |
A simple format for a student:
Education
Lakeview High School, Springfield, IL. Expected graduation: May 2027. GPA: 3.7. Honor Roll, varsity soccer, Spanish Club.
The high school student resume example shows a complete resume built around school, activities and a first job.
Can a long work history lead to age discrimination?
The law protects older applicants. The Age Discrimination in Employment Act (ADEA) forbids age discrimination against people who are age 40 or older, according to the EEOC. It covers any aspect of employment, including hiring, and applies to employers with 20 or more employees.
The ADEA also makes it unlawful for an employer to publish a job notice or advertisement that indicates a preference, limitation or discrimination based on age, under Section 4(e) of the ADEA.
Your resume is a marketing document, so you decide what to emphasize. Many experienced applicants keep the focus on recent work for practical reasons:
- Use the 10 to 15 year window. It keeps attention on current skills.
- Leave dates off older degrees. Keep the school and degree.
- Update your tools and terms. List current software and methods, and drop discontinued ones.
- Show recent learning. Add a current certification, course or project if you have one.
If you are 40 or older and changing fields, our guide to a career change at 40 covers how to frame a long career for a new direction.
If you believe an employer treated you unfairly because of your age, the EEOC website explains how to file a charge. For advice on a specific situation, talk with an employment attorney.
Common mistakes with older experience
- Listing every job since your first one. It adds pages without adding interest.
- Cutting relevant experience just because it is old. The rule is about relevance, not a strict date.
- Leaving an unexplained gap within your 10 to 15 years. Cover it with a short line for caregiving, school, freelance work or a career break.
- Keeping outdated skills to fill space. Old software names can make your whole resume look dated.
- Repeating the same duties for every older job. Combine them into an Earlier Career section and let your resume summary tie your experience together.
