i-Ready Diagnostic 4th Grade Sample Questions

The i-Ready Diagnostic is an adaptive online test that is intended to show your child’s understanding of Math and Reading and help figure out what your child is ready to learn next. As an adaptive test, questions will get easier or harder depending on how your child is progressing on the test.  Questions may range up to three grade levels above your child’s current grade.

The i-Ready Diagnostic is given in the following order for children in 4th Grade.
