i-Ready Assessment

What is the i-Ready assessment?

The i-Ready Assessment is an adaptive test that matches the difficulty of questions to each student's ability. The assessment starts each student at a difficulty level based on a best guess, including grade level. When a student gets answers right, the questions get harder; if a student selects incorrect answers, the questions get easier. It adapts to the ability of each student quickly and efficiently. 

The i-Ready Assessment identifies students’ strengths and weaknesses, while supporting data-driven differentiated instruction. It provides valid and reliable growth data, helping teacher track both yearly and long-term student progress. It does not replace daily instruction or curriculum. 

Who takes the i-Ready assessment?

It is administered to students in grades K-8.

How is the i-Ready assessment administered?

Students take the screener three times during the school year - at the beginning, middle, and end. It is typically administered in either two 30-minute sessions for older students or three 20 minute sessions for younger students.
