Excerpts from the Chicagotribune.com:

The Chicago Fire Department has canceled promotional tests scheduled for this week due to technical issues. Firefighters were sitting for tests this week to become lieutenants and chiefs, but the chiefs’ test scheduled for Wednesday was canceled due to a vendor’s technical problems.

California-based CPS HR Consulting, which was paid $1.4 million to administer the tests, apologized for the issue.

About 1,600 firefighters took the lieutenant’s exam, and there were 117 candidates for battalion chief.
