If you've been applying for jobs recently and wondering why you're not hearing back, there's a concept you need to understand. It's called an ATS score, and it might be the thing standing between you and getting an interview.
This post explains what an ATS score is, how it's calculated, and what you can do to improve yours.
What Does ATS Stand For?
ATS stands for Applicant Tracking System. It's software that companies use to manage job applications.
When a company receives hundreds or thousands of applications for a single role, a human being can't realistically read every single one. So they use an ATS to do the first round of filtering. The system scans each resume, evaluates it based on certain criteria, and assigns it a score. Resumes with higher scores move forward. Resumes with lower scores often never get seen by anyone.
Around 70% of large companies now use some version of this technology. That number is growing, not shrinking. For most corporate job applications, your resume goes through an ATS before a human ever looks at it.
What Is an ATS Score?
An ATS score is a number — sometimes a percentage — that represents how well a resume matches a specific job description.
The score is not a universal rating of how good your resume is. It's always specific to one job. The same resume can have a high score for one role and a very low score for a different role with a slightly different description.
The score is calculated based on keyword matching. The ATS reads the job description and identifies the key terms — skills, tools, job titles, certifications, and responsibilities. Then it scans your resume to see how many of those terms appear. The more matches it finds, the higher your score.
Some ATS platforms also look at formatting. A resume that's built with columns, tables, or unusual fonts can confuse the software, causing it to misread sections and lower your score even if the content is good.
Why Does the Score Matter?
Because in most companies, there's a cutoff. Resumes that fall below a certain score threshold get removed from the pool automatically. A recruiter might only look at the top 10% or 20% of applicants based on their scores.
This is why people with genuinely relevant experience get overlooked. Not because they're not qualified, but because the way they described that experience didn't match the keywords the ATS was scanning for.
You could have five years of experience doing exactly what the job requires, but if your resume uses different terminology than the job description, your score drops and you get filtered out.
What Factors Affect Your ATS Score?
Keyword and context signals
Keywords: This is the biggest factor. Your resume needs to include the specific skills, tools, and phrases that appear in the job description. Industry-standard terms, job titles, and software names all count.
Keyword context: Advanced ATS systems don't just look for keywords in isolation. They check whether the keyword appears in a meaningful context. "Managed" is more useful when it's followed by a description of what was managed and what the result was.
Job title match: If the title you held in a previous role is close but not identical to what the posting is asking for, that can hurt your score. Sometimes it helps to include the job posting's title in your summary when it's accurate and appropriate.
Skills section: Many ATS systems specifically scan the skills section of a resume. A clearly formatted skills section where you list tools and competencies helps the system find what it needs quickly.
Structural signals
Formatting: Clean, simple formatting helps the ATS parse your resume correctly. Complex layouts with multiple columns or graphic elements can cause the system to misread your content entirely.
Relevant certifications: If the job description mentions specific certifications and you have them, make sure they appear on your resume with the exact name the employer used.
How to Improve Your ATS Score
Read the job description like a checklist. Go through it and identify every skill, tool, responsibility, and qualification they mention. These are the keywords your resume needs to include.
Close the gap. Compare those keywords to what's currently on your resume. For every keyword that's missing where you actually have the relevant experience, update your resume to include it.
Use natural language. Don't just cram keywords into your resume randomly. Incorporate them into your bullet points and descriptions in a way that sounds natural and tells a story about what you've done.
Clean up your formatting. Use a single-column layout, standard section headings, and common fonts. Remove tables, text boxes, and graphics if you have them.
Quantify your results. Some ATS systems and all human reviewers respond well to numbers. Instead of "managed a team," try "managed a team of eight across three departments." Specificity signals competence.
Tailor for every application. A resume you optimized for one job description won't automatically be optimized for the next one. Each posting has different keywords. Take 15 to 20 minutes to adjust your resume for each role you apply to.
One Last Thing
A high ATS score gets your resume in front of a human. That's its job. Once a recruiter picks up your resume, the score doesn't matter anymore — what matters is whether your experience, achievements, and clarity make them want to call you.
So optimize for the ATS, but don't sacrifice readability. Your resume needs to work for software and for people.
Resuma shows you your ATS score before you apply. Paste your resume and the job description, and you'll see exactly how well they match and what you need to change to improve your score. Fix the gaps before you submit — not after you've already been filtered out.
