INDIANAPOLIS (AP) _ An independent reviewer looking into interruptions in Indiana's standardized tests is recommending roughly 1,400 results be tossed out.
 
Richard Hill told Indiana's state Board of Education Wednesday that the widespread testing interruption appeared to have minimal impact. But he added that some test results should still be invalidated to assure the integrity of overall scores.

Hill runs the National Center for Improvement of Education Assessment.
 
School Superintendent Glenda Ritz said the release of the ISTEP scores has been delayed until next week to allow schools to review test results which have been marked for invalidation.
 
Administration of Indiana's standardized test was disrupted last spring when students were kicked off CTB/McGraw-Hill's online test. The national testing company said its online servers were overloaded by too many test-takers.
