Account Structure

There are three different accounts that each TJHSST student has:

  • FCPS domain

  • CSL domain

FCPS Domain

The FCPS domain is controlled by the FCPS IT department. Students use their FCPS domain password to access:

  • Schoology

  • SIS StudentVue

  • FCPS Google Apps for Education

  • FCPS computers (those running Windows 10)

Password resets on the FCPS domain are handled on the first day of school in homeroom (on a teacher laptop). Questions should be directed to

CSL Domain

The CSL domain is controlled by the TJHSST Student Systems Administrators. We use Kerberos to handle authentications in the CSL realm (CSL.TJHSST.EDU).


Students use their CSL domain password to access:

  • Ion

  • Director

  • Webmail

  • Remote Access Servers

  • Workstations

  • and other CSL resources

Passwords are prompted to be reset the first time you login to Ion. Questions should be directed to
