What is an ATS Score and How to Improve It

Your ATS score is a numerical rating — typically between 0 and 100 — that represents how well your resume matches a specific job description. It's the first hurdle your resume must clear before a recruiter ever lays eyes on it. According to the Bureau of Labor Statistics, there are over 900,000 HR specialists in the United States alone — and the vast majority rely on ATS software to manage the volume of applications they receive.

How ATS Scoring Algorithms Calculate Your Match

ATS platforms analyze several factors when scoring your resume. Each factor contributes to your overall compatibility percentage:

• Keyword match rate — How many of the required skills and qualifications from the job posting appear in your resume. This is the primary scoring factor
• Relevance of experience — Whether your job titles and responsibilities align with the role being filled
• Skills alignment — Technical and soft skills that match the job requirements, weighted by priority
• Education and certifications — Required qualifications, degrees, and professional credentials
• Formatting compliance — Whether the ATS can properly parse your resume structure without errors

Modern ATS platforms like Workday, Greenhouse, and iCIMS use natural language processing to go beyond exact keyword matching. They can recognize synonyms, evaluate context, and even assess the recency of your experience. This means your optimization strategy needs to be more sophisticated than simply copying keywords from the job posting.

What Is a Good ATS Score for Job Applications?

Most recruiters set their ATS to surface candidates scoring above 70-80%. Anything below 60% is typically filtered out entirely. The sweet spot is 80% or above — this tells the system your resume is a strong match for the position.

However, the threshold varies by company and role. High-volume positions like customer service or retail may have lower thresholds (60-70%) because companies need to fill multiple positions quickly. Specialized roles like software engineering or data science often have higher thresholds (80-90%) because the recruiter is looking for very specific technical skills. Research from SHRM suggests that companies with over 250 employees are most likely to use strict ATS scoring thresholds.

How to Improve Your ATS Score: 4 Actionable Strategies

1. Analyze Your Resume Before You Apply

Before submitting your resume, run it through an AI resume optimizer like RiResume to see your real-time ATS compatibility score. This shows you exactly where you stand and what needs to change. Without this baseline, you're applying blind — and potentially sending a resume that will be filtered out before anyone reads it. Our complete AI resume optimization guide walks you through this process in detail.

2. Close the Keyword Gap Strategically

Identify which keywords from the job description are missing from your resume and add them naturally. Don't keyword-stuff — integrate missing terms into your experience bullets and skills section in a way that reads naturally. Focus on three categories: hard skills (technical competencies), soft skills (communication, leadership), and industry-specific terminology. Each category should be represented proportionally to how often it appears in the job description.

3. Tailor Your Resume for Every Single Application

A resume that scores 90% for one job might score 50% for another because the requirements are fundamentally different. Each job description has unique requirements, so customize your resume for each application. AI tools can automate this process significantly — learn exactly how in our guide to tailoring your resume for every job application.

4. Use the Right File Format for ATS Compatibility

Submit your resume as a .docx file unless specifically asked for PDF. Use standard section headers (Experience, Education, Skills) and avoid tables, text boxes, and multi-column layouts that can confuse ATS parsers. Even a beautifully designed resume will score poorly if the ATS can't parse it correctly.

Common ATS Score Myths That Hurt Job Seekers

There are several persistent myths about ATS scoring that actually hurt your chances. First, many job seekers believe that adding invisible keywords in white text will boost their score. Modern ATS systems detect and penalize this practice. Second, some believe that a generic "optimized" resume works for all jobs — it doesn't. Each application requires tailoring. Third, some candidates think ATS scoring is purely about keywords, when modern systems also evaluate formatting, structure, and contextual relevance.

The most effective approach is to treat ATS optimization as a complement to strong content, not a replacement for it. Your resume needs to pass the machine screening and impress the human reviewer who reads it afterward.
