Kansas schools already struggling to administer math and reading assessment tests have another problem to deal with.
State education officials say unknown people launched cyber attacks against the tests last week. The Topeka Capital-Journal reports the attackers slowed down or disabled networks used to administer the tests by overwhelming them with traffic, rather than hacking into them.
The attacks started Thursday and briefly stopped on Sunday. Testing ran smoothly on Monday but the cyber attacks resumed on Tuesday.
Officials from the Kansas State Department of Education and the University of Kansas testing center said Tuesday no student data were compromised.
The tests have already been plagued by technology problems this year, prompting several districts to delay or cancel administering them.
