The Iowa Acceleration Scale (IAS) has been developed to guide educators in making important decisions regarding whether or not particular students are good candidates for whole-grade acceleration (grade-skip). The IAS is designed for use with students in grades K-8. It is an appropriate guide for early entrance to kindergarten or first grade. The IAS Manual is an easy-to-read monograph that is designed to be used as a reference guide in conjunction with the IAS Form, since the manual contains explanations and instructions for filling out each item in the Form.
