Integrated Time and Attendance System (ITAS) at NIH


The Integrated Time and Attendance System (ITAS) is an automated timekeeping by exception system. ITAS records employees’ work schedules, Voluntary Leave/Voluntary Leave Transfer Program hours, Telework requests and all leave requests for NIH staff.

As an employee, you can Sign In and Out (if required,) Verify your timecard (if required) at the end of each pay period, and request all leave categories. If you are eligible for Telework, you can request a non-scheduled Telework day, or change your regular Telework schedule.

As a Timekeeper or Administrative Officer in ITAS, you can act on behalf of an employee and create leave requests, update profiles, add premium pay to timecards, process other actions and download reports, appropriate to your access.

As a Leave Approving Official (LAO), you can approve/deny leave requests, approve/deny Telework requests, manage timecards and download reports.
