Each year, Assumption students complete required testing through the Archdiocese of        St. Louis known as the Iowa Test of Basic Skills (ITBS). The test has been in use throughout the United States for years, and measures students in grades 3-8 in primarily two areas: Reading and Math.

Providing data for each student in Reading and Math, the ITBS Test provides a data comparison of how each child scores against other children throughout the United States, who took the same test, in the same season, and in the same grade. Ultimately, a score (called a Percentile - %ile) for a third grader at Assumption School might be a 97%ile in Total Reading, meaning that this student scored above 96 students out of 100 from across the nation. The “Normal Curve,” shown in the graph below, shows how MOST students will have Percentiles in the AVERAGE range. As student’s progress to the right of the average range, they score higher Percentiles and are considered above average to outstanding or between the 97-99 %ile in the Total Reading area, as an example.

Before looking at the student’s Reading scores, here are some important reminders to keep in mind:

  • We experienced two years of COVID virtual learning that was difficult.
  • Some years have missing scores because we did NOT test due to COVID restrictions.
  • Over the last year, all schools have tried to catch students up on what they lost during the COVID time.

Below are the READING Growth Charts for Assumption School by Grade Level for this year. The LIGHT GREY LINE SHOWS typical growth for the grade level - over the years (beginning at third grade) and ending in their latest grade level.

The BLACK LINE shows the growth of Assumption students over the years by Grade Level. 

The SPAN (space) between the Grey and Black line is the GROWTH for that class over the years.

Also, remember that for third graders, this was their first time taking the ITBS, so the dots represent the typical (expected score – GREY) and the ACTUAL score (BLACK dot).

Overall, the growth for all grade levels except sixth was above the expected growth. Sixth grade dipped by a hair, but this is not significant as they went from 59%ile (as a group) to 52%ile (as a group), which is considered “statistically insignificant.”

Stay tuned! Next week, we’ll take a look at Assumption Math scores.
