Orientation and Mobility Severity Rating Scale - Information and Guidelines (Revised 2013)

This is the 2013 update of the Orientation and Mobility Severity Rating Scale (O&MSRS) and the Orientation and Mobility Severity Rating Scale for Students with Additional Needs (O&MSRS+). The Michigan Department of Education-Low Incidence Outreach (MDE-LIO) Orientation and Mobility Task Force has revised the forms so that they may be filled in on a computer or iPad.

The Vision Services Severity Rating Scale (VSSRS) has been developed to assist the Teacher Consultant for the Visually Impaired (TCVI) or Teacher of the Visually Impaired (TVI) in making recommendations for services to students who are blind
or visually impaired in the state of Michigan.
