How the ATS Resume Score Works

ATS Signal is a rules-based text scanner. It does not access an employer's applicant tracking system, and it does not reproduce any vendor's proprietary ranking. The score is a planning heuristic: a way to prioritize edits, not a prediction of hiring.

Score components

Component	Points	What it checks
Contact details	10	Email, phone, and LinkedIn URL in plain text.
Core sections	20	Summary, Experience, Education, and Skills headings (5 points each).
Content evidence	25	Action verbs, metrics, bullet volume, and resume length.
Formatting signals	10	Table-style pipes, unusual characters, and basic length/readability checks.
Job match	35	Weighted coverage of the top terms extracted from the job description.

With a job description, the five components add up to 100. Without one, the general components (65 points) are normalized to a 100-point scale and the report says the scan is general. The job match is more useful because it reflects the employer's language.

Confidence and the estimated range

The point score is paired with a confidence level and an estimated range. Confidence is calculated from input completeness and extraction quality: whether a job description was provided, how much usable resume text was found, how many standard sections were detected, whether unusual characters or table-style text appeared, and how many job terms were extracted.

High confidence means the scan had enough clean text to be useful. It does not mean the score is an employer's score. The range is deliberately not a probability: we have no data on interview outcomes and no access to an employer's ATS. A score of 85 with a 78-92 range means "around this level, with this much input uncertainty," not "an 85% chance of an interview."

How keywords are extracted

The tool tokenizes the job description, removes common stop words, and builds one-, two-, and three-word candidates. Repeated phrases receive more weight, and phrases are ranked above isolated generic words. The top 24 candidates are compared with the resume text using phrase or word-boundary matching. The first eight terms carry weight 3, the next eight weight 2, and the rest weight 1.

This is intentionally transparent. It can miss synonyms, acronyms, and terms split across lines. It can also reward a term that appears once in an unrelated context. That is why the report shows the matched and missing terms rather than only a number.

What the scan cannot see

• How a specific ATS parses a specific layout or file.
• Whether a recruiter will value your experience, education, location, or timing.
• Whether a job is already filled or has an internal candidate.
• Whether a PDF's visual columns are scrambled; use the extracted-text panel as a warning, not a guarantee.
• Skills you have but did not mention. The scan only reads the text you provide.

Privacy and reproducibility

The analysis runs in the browser using the file you selected. No resume text is sent to our server. The same text and job description should produce the same score in the same version of the tool. If you change the job post, the keyword set and match score will change.

How to use the score

Read the high-severity issues first, inspect the extracted text, then use the missing keywords as prompts for truthful edits. Rescan after a substantial revision. Stop when the report is mostly polish; the goal is a clear application, not a perfect number.
