What are ATS requirements?

An applicant tracking system (ATS) is the software employers use to collect applications. It reads your resume into fields (name, contact details, jobs, dates, education, skills) and lets recruiters search them. Its requirements come down to two things: it has to be able to read your resume in the right order, and your resume has to contain the keywords a recruiter searches for. Everything below serves one of those two.

Frequently asked questions

What does an ATS need from a resume?

Text it can read and put in order: a text-based PDF or Word file, one column, standard section headings, and each job with a title, employer and dates. Then it needs the keywords recruiters search for, from the job description, used where they’re true for you.

Should I send a PDF or a Word file?

A text-based PDF works with modern ATS and keeps your layout. Send Word (.docx) when the posting asks for it, or when a recruiting agency wants to edit it.

Is there a real ATS score?

No. ATS software doesn’t give your resume a public score. What matters is whether it can read your details correctly and whether your resume contains the terms a recruiter searches for. That’s what this checklist covers.

How do I check my resume against this list quickly?

Run it through a free ATS checker. ATS Perfect’s checker reads your file the way an ATS does and lists what to fix, item by item.
