An applicant tracking system (ATS) is software that helps an organization manage recruiting for open roles. It gives recruiters and hiring managers a shared place to create openings and collect applications. The system can organize candidate information and record decisions as people move through the hiring process. Applicants may provide details through an online form or submit a resume that the ATS organizes into a profile. Teams can move each profile through stages such as initial review, interviews and an offer. Some platforms automate messages or provide search and scoring tools, though features vary. An ATS supports recruiting work, but it does not by itself determine whether someone is suitable or guarantee a fair hiring decision. Its usefulness depends on how the organization configures it and how people use the information it contains.

How does an ATS manage an application?
The process often starts with a job requisition. It describes the role and may document approvals required before recruiting begins. Once the opening is ready, the organization can publish it on a career site or a job board. Recruiters may also use sourcing to identify people who have not applied directly. Applications from different channels can then be brought into a shared workflow, depending on the system and its connections to other tools.
When someone applies, the ATS creates or updates a candidate record. That record may include a resume and contact details along with responses to application questions. Recruiters can assign a status such as “under review” or “interviewing.” The system may send an acknowledgment or notify a reviewer when feedback is due. After an interview, for example, a hiring manager can add feedback to the record so the recruiting team has information for its next decision.
Organizations configure stages and permissions to fit their process. A hiring manager may review applicants for a particular role while recruiters manage the broader workflow. Consistent stages help a team understand where applications stand and where follow-up may be needed. However, the ATS reflects only the information people enter and the steps they configure. Missing updates can make a record inaccurate, so clear ownership of each task matters.
What information and tools can an ATS include?
Common ATS capabilities include job requisitions, application forms and candidate profiles. Many systems also support interview coordination and recruiting reports. Some can parse resumes by extracting details such as work history or skills. This can make candidate records easier to search, although extracted information may need correction. A resume can be read by both people and software more easily when its layout is clear. An ATS-friendly resume is designed with that readability in mind.
Communication tools can keep messages and interview feedback alongside an application. Reporting features may show how many candidates are at each stage or how long openings have been active. These reports can help teams notice bottlenecks and follow up on delayed decisions. They are only as reliable as the updates entered by users, however. If people skip status changes or record them late, reports may not represent the current workflow.
An ATS may connect to other tools rather than manage every hiring task itself. For example, an organization may link it to an HRIS or to onboarding software so selected candidate information can move into a later process. Integrations can reduce repeated data entry, but they also require decisions about which system holds the authoritative record. Organizations should define who can access candidate data and how information is transferred or updated. Those practices help reduce confusion when multiple systems contain related details.
Does an ATS automatically decide who gets hired?
Not necessarily. A basic ATS may organize applications and let people search or filter them. Other systems offer automated screening or ranking based on resume terms or application answers. These functions can help recruiters handle large volumes of applications, but a match score does not prove that someone is qualified. A candidate may describe a relevant skill in different words from those used in a job posting. Resume formatting can also affect what the software extracts.
Organizations should connect screening criteria to the actual requirements of a role and review how the tool behaves in practice. A ranking or filter can determine which applicants receive human attention, even when the system does not make the final decision. Employers using algorithms or other hiring technology must consider whether the process unfairly excludes qualified people with disabilities. The Department of Justice guidance on hiring technology and disability discrimination explains that employers may need to provide reasonable accommodations or an accessible alternative during the hiring process.
When an ATS uses artificial intelligence, an organization can use risk-management practices to examine how the system is designed and applied. NIST describes its AI Risk Management Framework as voluntary and intended to help organizations manage risks associated with AI systems. The NIST AI Risk Management Framework can provide a structure for that work. It does not replace applicable legal requirements or careful human oversight. Reviewing outcomes and providing a way to address problems are important parts of responsible use.
How is an ATS different from related systems?
An ATS focuses on candidates and recruiting workflow. Recruitment is the broader activity of attracting and selecting people; an ATS is one tool that can support it. A job board mainly helps people find openings and may collect applications. An ATS can bring applications from different sources into one process and preserve a record of hiring activity. The exact boundary depends on the product, since some job boards and recruiting platforms include overlapping features.
An ATS is also distinct from an HRIS, which commonly supports employee information and administration after a person is hired. A background check is a separate screening activity. An ATS might help initiate a check or record its status, but that does not mean the ATS provider performs the check. Similarly, an ATS is not a payroll system, which supports pay-related work. Each tool may have a different purpose and different access rules.
Some platforms combine multiple functions, while others exchange information through integrations. Software category names do not always reveal exactly what a particular product does. It is useful to map each step in the organization’s process and identify which system owns the record or action at that point. This makes it easier to understand where information originates and who is responsible for updating it. Clear boundaries also help prevent teams from assuming that one system covers tasks handled elsewhere.
How can an ATS fit into contingent workforce management?
An ATS can be useful when an organization recruits for temporary or project-based assignments, provided its workflows support that type of opening. It may collect candidate details and coordinate interviews. It can also record a hiring manager’s decision. That recruiting record helps clarify who was considered for an assignment and where selection stands. A contingent worker may then move into separate steps for assignment administration or worker onboarding.
In some programs, an ATS works alongside a Vendor Management System (VMS). The ATS may support recruiting and candidate review, while the VMS may manage contingent requisitions or other program activity. The division of work varies by organization and system design. Teams benefit from defining how candidate records and decisions pass between systems. Clear handoffs can help avoid duplicate entry and make it easier to identify which team owns the next action.
For organizations using contingent workers, it is important to clarify who handles each step after selection. Recruiting software may not manage checks or assignment administration. It may also not cover timekeeping or payroll. Those responsibilities can sit in other systems or with other parts of the operating model. In contingent workforce management, an ATS is one possible part of the broader process rather than a complete record of everything that happens during an assignment. Defining its scope helps teams use it for recruiting without assuming it replaces systems for later workforce operations.
