Generally speaking, how do St. Thomas students perform on standardized tests compared to students in the public school?
It is a bit like comparing apples to oranges because the local public school students and St. Thomas students do not take the same test. The Rockford Diocese administers the Iowa Test of Basic Skills (ITBS) to its schools. The majority of Catholic schools across the country take this test as well as host of public districts in various states. St. Thomas students perform well on this test, with most class averages in the above average ranges for stanine, percentile, and grade equivalent.
