The data collected from these assessments can help you determine whether foundational reading skills are being established at an appropriate pace, pinpoint specific gaps in knowledge, and plan appropriately targeted instruction. The results of these surveys can be plugged into our Grouping Matrix, a free, web-based system that enables you to group students according to the type and depth of their decoding difficulties.

How can you use data to group students according to their decoding strengths and weaknesses?
Use our complimentary, web-based, password-protected, secure student data management interface, the Grouping Matrix. It enables you to group students (K-12) according to the type and depth of their decoding difficulties using data from grade-level Oral Reading Fluency passages (such as DIBELS, AIMSWeb, Six Minute Solutions, Read Naturally, EasyCBM) and our complimentary diagnostic assessments. If you have questions about the Grouping Matrix please email us.
