Employers have the choice of three methods for candidates to submit job applications:
1) via the ClearanceJobs.com website, 2) via external URL, 3) via email address.
When method one is utilized (via the ClearanceJobs.com website), we have the ability to track when/if the job application is read. The "n/a" status pertains to job applications from methods two and three above. Since we cannot track whether or not a job application submitted through an employer's website or email address has been viewed, the status is reflected as "n/a."
