The AIR Self-Determination Scale was developed by the American Institutes for Research (AIR), in collaboration with Teachers College, Columbia University, with funding from the U.S. Department of Education, Office of Special Education Programs (OSEP). Discussion of how to use the scales, validity, reliability, and factor analysis can be found in the guide. All four scales, calculate the level of self determination. The authors of the scale argue that the scales can be used to promote discussion and measure progress over time. Three of the scales, Educator, Student, and Parent, can be found on my google site with the associated spreadsheets. I have entered formulas to calculate all of the scores as instructed in the guide. To use the scales, you need to make a copy of the spreadsheet (data file). After each entry, the formulas will need to be copied from the example student row to the new student.
