COLUMBUS, Ind. (AP) – School districts across Indiana are reporting problems with a test run for the ISTEP+ exam.

The Republic reports (http://bit.ly/1sEfnzx ) this week's trial was meant to ensure that local technology and ISTEP+ servers were working properly before 470,000 students take the online portion of the exam this spring. 

Bartholomew Consolidated School Corp. Superintendent John Quick says only 21 of more than 2,400 computers could load the practice test in his district. Other students experienced multiple disconnections. 

CTB/McGraw Hill spokesman Brian Belardi says the company is confident the connection issues will be resolved before the test is administered.

About 29 percent of Indiana students who took the test in 2013 experienced disruptions because the company's servers weren't prepared for the large number of students online at once.
