The Minnesota Department of Education suspended online testing Wednesday for the second time this spring in the wake of another cyberattack that hobbled the vendor's computer system and prevented students across the state from completing standardized science exams.
The computer problems, which have repeatedly plagued test takers this year, also spurred a blistering response from frustrated lawmakers, teachers and state education officials. Minnesota Education Commissioner Brenda Cassellius questioned whether Pearson, the state's testing vendor, has done enough to safeguard its system.
"It is simply unacceptable and unfair to subject students and teachers to this kind of uncertainty in a high-stakes testing environment," Cassellius said.
The commissioner said that after its last suspension April 21, the company told state leaders it added new security measures to prevent future disruptions. "Given the need to suspend testing today, I have questions about Pearson's ability to follow through on their assurances," she said.
Department officials suspended testing around lunchtime Wednesday and hours later informed school districts that testing would not resume on Thursday.
About 44,000 Minnesota students from around the state still need to take the science exam by Tuesday's deadline, but education officials were unsure how many students were affected by Wednesday's disruption.
Students who attempted to take the Minnesota Comprehensive Assessments (MCA) science exam Wednesday had difficulty logging on or were thwarted by Pearson's sluggish system.
Pearson officials described the attack Wednesday as larger and more sophisticated assault on its system than the one that occurred April 21, which prompted the state to suspend testing for about a day. Company officials said they are working to strengthen the system.
