INDIANAPOLIS (AP) — The new vendor chosen to administer the ISTEP+ exam to Indiana students is promising that next spring’s wave of testing won’t be marred by the glitches that plagued its predecessor.

But Pearson Education Inc., which replaced CTB/McGraw-Hill in March as the vendor for Indiana’s standardized student tests, has its own history of scoring errors, computer glitches and testing delays.

The Indianapolis Star reports that the National Center for Fair & Open Testing has identified 43 issues with Pearson-administered tests since 2000. Those include scoring errors, computer glitches and testing delays

State officials were aware of previous issues with Pearson’s performance, but state regulations don’t allow past performance to be considered in evaluating competitive bids.

The company says it’s launched a new testing program that’s nullified past glitches.
