Some Indiana school officials say students faced frozen screens and error messages during a test run of the online ISTEP exam.
Wayne Township Schools superintendent Jeff Butts said many students in the suburban Indianapolis district faced technical troubles during Wednesday's readiness test. A new contractor handled the assessment.
Butts told The Indianapolis Star that students can't afford to have such problems during a timed exam.
Greenwood schools officials said they sent students back to class when the readiness test wouldn't load.
Pearson Education is running the ISTEP exam that begins in February under a $33 million, two-year contract. Pearson spokesman Scott Overland said the practice test is designed to stress the system so problems can be corrected.
Similar glitches occurred under previous vendor CTB/McGraw Hill.
