Standardized Test Results – ITBS Test

This year OCS, in conjunction with all Catholic Schools in the Owensboro Diocese, administered the ITBS Achievement Test in place of the CAT6 Achievement Test. The ITBS is a more comprehensive and rigorous test. Teachers use the results to guide instruction within the classroom.


The scores reflect a National Percentile Rank. It is determined by comparing how well our students did with other children across the nation who took the same test. For example, if OCS scored in the 78th percentile, this translates to OCS students performed better than 78 percent of the others who took the same test.

The “average” score would be the 50th percentile, and you can see by looking at the tests that OCS students score well above the national average!
