The Oklahoma State Department of Education confirmed on Friday there was another "outage" that disrupted testing.
Unlike Monday, this one was brief; it was just 5-10 minutes and affected 11 school districts instead of the entire state.
Students had windows pop up telling them to exit the test, but they weren't kicked off and were able to complete the test.
The state says it mainly affected smaller districts, but they don't know the number of students impacted.
The mandatory testing was suspended at public schools on Monday. The problems were on a statewide level after issues with servers at CTB/McGraw-Hill, the testing vendor.
The system meltdown that happened was resolved and everything was back to normal the next day.
The state said 61,000 students took online tests on Tuesday and there were no significant problems.
