We did research to find the Catile levels for each grade. The data is collected from students in the United States with a size of over 500 thousand samples. You can see the results in the table below.
The table shows the range of Catile levels suitable for a certain grade. As an example, for grade 5 students, texts with Catile levels between 795C and 1100C are suitable. You can also say a text with 900C is suitable for grade 5 and grade 6 students.
