The Integrated Time and Attendance System (ITAS) is NIH’s timekeeping system. It records employees’ work schedules, leave transfer program hours, telework requests and all leave requests.


An employee can:
  • Verify their timecard
  • Request leave
  • Request ad hoc telework day
  • Change their regular telework schedule
  • Request a tour of duty change
A timekeeper or Administrative Officer can act on behalf of an employee and:
  • Create leave and telework requests
  • Update profiles
  • Add premium pay to timecards
  • Download reports
A Leave Approving Official (LAO) can:
  • Approve/deny leave, ad hoc telework, and tour of duty change requests
  • Manage timecards
  • Download reports
