Are ATS resume checkers accurate?

They're estimates. They can reliably catch parsing problems and missing keywords, but no checker can reproduce a specific employer's ATS settings.

What is a good ATS resume score?

The reasons behind the score matter more than the number. Fix every parsing issue and cover the job's must-have keywords you genuinely have.

The best ATS resume checkers for software engineers

By Mubeen Jawed, founder of ResumeForDev · Updated November 7, 2026

Short answer

An ATS resume checker scores how well your resume will parse and how well it matches a job's keywords. For software engineers, the most useful checkers explain their score and know technical vocabulary. ResumeForDev's free checker scores developer resumes with seven fixed rules and lists missing keywords from a pasted job post, with no sign-up. Jobscan specialises in detailed job-description matching, Resume Worded gives general resume and LinkedIn feedback, and Enhancv and Teal include checkers alongside their builders.

Key points

No checker runs a company's real ATS. They estimate parsing and keyword match.
Prefer a checker that shows why you lost each point.
Paste the job description: keyword gaps are the most useful output.
Developer resumes need a checker that understands technical terms.

What an ATS resume checker actually checks

Applicant tracking systems such as Greenhouse, Lever and Workday parse your resume into fields and let recruiters search it. A checker estimates two things: whether your file will parse cleanly (text-based, standard sections, dates), and how many of the job's keywords appear. Some also grade writing quality, like action verbs and quantified bullets. None can tell you what a specific employer's ATS will do, because those settings are private.
